Hey guys... I'm looking at a 1995 Sport Nautique with a Pro boss / Pro tec setup on it. The boat has SUPER low hours (200ish) and I only put on around 40 hours per year. Do we have any data on how long these Pro tec systems work before they need to be retrofitted to carb/dizzy? If they aren't typically causing issues until 500+ hours then it's a no brainer to buy the boat in question. Thanks for any help in advance ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Buy It. At 200 hours it is like new in most areas. It will need some normal maintenance as all old boats do but should last you a long time. The Pro Tec may out last you or fail this year but how often do you find a boat with 200 hours that is 24 years old. I bought mine with 99 hours in 2014, had to go through the whole boat to get it ship shape. A couple sensors were not working right, the hydraulic rams that hold up the passenger seat, engine cover and the dash glovebox lid were all not working but easy to repace with new ones.. The rubber flapper on the exhaust was rotted out not from use but just from age and this boat sat in a garage for 20 years.. Changed all oils, Engine and Tranny. New rope seals in the rudder and prop shaft and a few trips to the lake to sort out other stuff and the boat treats me like a brand new boat. Mine also needed a new prop shaft and strut was bent from the previous owner hitting something. About $1,500 later it was in great shape again. Even if the Pro Tech fails it is not that expensive to switch back to a Distributor and Carburetor. I would buy it if it fits your needs. Engine work is easy, fixing seats and a lousy exterior is hard to me. Good Luck Mark ------------- |

Thanks for the advice. I put a deposit on it yesterday. :) I can't wait to get out and enjoy it.... next year hahaha. I had someone view it for me and says its the best condition boat of that vintage I'm going to find. I get to pick it up next weekend. ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

I always thought the ProTec setup disappeared after 94 and the GT40 came along in 95. If that's the case you either would have a 94 model year boat with ProTec or a 95 with a GT40 Maybe I'm confused

My 95 Pro Boss is the Port Fuel Injected version, first released in 1995. Our boat is a May of 1995 build. No idea when it was first used. ------------- |

Don’t want to put words in Tims mouth but what he is saying is that the GT40 was an engine upgrade. It seems most boats had them but other engines could be had. Maybe someone thought I don’t want one of those fancy multi port engines I would rather have a tried and true Pro Tec’s and maybe save a few bucks too. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

The Serial number on the back of the boat will tell the build date and we will at least know that for sure. It may be a 94 sold in 95 or as you suggest a carry over engine purchase. ------------- |

The Engine looks pretty clean so it really makes the rust stains stand out near the spark plugs And the cover over the battery cable connection on the starter is pretty discolored like there's been rusty water dripping on it. It looks like you have GT40 heads and they've been known to crack externally and leak like that. It's probably worth a close look If you're looking for all that other GT40 stuff, add a distributor to your list too I won't comment on how Sport is spelled |

Hmmm... I was under the impression that the stains would have come from the exhaust risers. I know for sure the other side has a leaking riser. Seeing that the rust is uniform across the center of the head... I'm hoping that's the case. I think I know where there's a dizzy/coil/harness setup I can have at a fairly reasonable price to team up with the GT-40 intake setup eventually. Those decals are coming off hahahaha. ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Figured I'd mention the stains, probably worth a good look. I figure you'll be finding fuel pumps and fuel lines etc to go with everything else. So many things to find and change, I'm sure there's more. Good lookin' boat by the way. |

That's a nice looking boat looks to be well cared for. As to GT parts they are out there and do come up from time to time. There was recently a set up on Seattle craigslist for pocket change - in under a day it was gone. Another place to keep an eye out is fishtheclassic a Shamrock web forum. This summer someone had the parts for one as well and that's where I found a complete engine. Put something up on the wanted section of these sites who knows? One thing for sure they turn up when your not needing them..... ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

I picked up the Sport Nautique today! We had a couple small hiccups... the hitch was frozen in the back of the truck after driving through a huge snow storm. The wiring for the lights was incorrect and the LED lights were shot. That took a few hours and a couple trips to automotive stores to rectify. There's a fun story with all of this... but I'll save that until the end.

Well I finally got to take the Sport Nautique out for a test run today. I had the lake virtually all to myself... it was calm... there was snow on the hills around the lake... it was magic. The Sport ran overall pretty good. At first it felt like it was hitting a wall at 4000 rpm then quickly ripped up to WOT 44 mph gps @ 4800 rpm. After a little cruising around it had no issues accelerating to WOT. Here's a few pics :) https://flic.kr/p/2hxuYNc" rel="nofollow">  https://flic.kr/p/2hxuYNc" rel="nofollow - 3F307695-BCEA-414F-A0E4-D3D0D39E5E97-1 by https://www.flickr.com/photos/184883997@N04/" rel="nofollow - Dwight Kinley , on Flickrhttps://flic.kr/p/2hxrfPE" rel="nofollow">  https://flic.kr/p/2hxrfPE" rel="nofollow - IMG_1514 by https://www.flickr.com/photos/184883997@N04/" rel="nofollow - Dwight Kinley , on Flickrhttps://flic.kr/p/2hxtZbc" rel="nofollow">  https://flic.kr/p/2hxtZbc" rel="nofollow - IMG_1516 by https://www.flickr.com/photos/184883997@N04/" rel="nofollow - Dwight Kinley , on Flickr------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Some of the Nautiques sold by Century Marine were used in Firebird Lake. There is a ski club that has rights to the lake and maintain ski courses and jumps. Also, the ASU ski team uses it. The lake is salt water and if your boat was used there it could explain the rust on your engine. A friend of mine bought his '94 from Century and he found out later it was a ASU team boat used at Firebird. His risers/manifolds failed prematurely. Since the lake is in the desert the boats don't show any sign of being in salt water/air except for the exhaust. Also, your boat has the exact same trailer as his '94 made from C channel so no rusted tubes. I believe they where made by Pacific Trailer. |

No tower, no reverse, destroyed upholstery, no stringer guarantees... $1500. Gotta deliver it next month. The best part of the day is putting a cold beer in the cupholder awaiting your return from skiing.

With this boat... both times I've gone out on the water... it doesn't want to go past 4000 rpm until it warms up. You can mash the throttle and it simply will not go past. Once it warms up a little... the full rpm range is there. And when it kicks in and goes beyond 4K rpm... it kicks in HARD. I popped off the air cleaner while it was idling so I could inspect the Pro boss injector pods and they seem to be spraying just fine at idle up to 1500 rpm. I didn't feel comfortable with the crew I had today to run it at speed in the 4K rpm range and watch the injectors. Do you guys have any thoughts on what the issue might be? ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

I do not know the Pro Tec programming at all but it sounds like it has a cold run program. Once warm it gives you full power. Nothing wrong with that if that is all it is. An engine should run till at full temp before anyone hits full throttle. It is hard on the engine if you do not warm it up first and you risk engine damage. Pistons under full throttle grow faster than the cylinders they run in. Many a driver have stuck a piston in a cold engine, you don't want to do that. But more important, your son looks very happy in his new boat and you are looking good cutting up the water. ------------- |

Well.... realized some bad news today.... I knew there was fuel coming from all 4 injectors.... but I didn't realize that at idle they're supposed to be "spraying" as opposed to "dribbling." I was under the assumption at first that my rich idle was the FI trying to get the engine warmed up .... but nope it's the injectors. All of them are dribbling. Unless they can be cleaned I think I'm hooped. So I think I'm going to have to do the carb retrofit. I'm disappointed... but at the same time it will be nice to get this sorted over the winter. It appears as though everyone out there who has done the skidim carb retrofit has been very happy with it. While doing the carb retrofit.... I'll probably do the DUI as well. So here's the thing... the Protec ignition system seems to be working flawlessly on the boat currently. It ran beautifully up to 44 mph @ 4800 rpm. Is the used protec setup worth anything? Anyone out there want a low hour spare protec system when I pull it off? Ive read through a few threads already on the carb / dui conversion and it seems pretty straightforward. I've done a distributor swap on the 86 Nautique. Does anyone have any recommendations/thoughts? ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

I gave my old ProTec stuff away. I should have kept the injectors. Reminds me of the EFI/ProTec swap I did a couple of years ago. My 1994 runs as strong as and maybe better than new (but that’s gut feeling). I was on Lake Powell last week with my 1994 SNOB and a 2006 Ski Nautique (206) with the GM 343 HP engine. My 1994 was waaaay stronger with better hole-shot. We were all surprised by that. The 206 did have better cold starting characteristics...

A simple trick to clean injectors is to put a quart of ATF fluid in the gas tank and go out and run it. I have seen it work many times to free up sticky injectors. It will not hurt anything and for about $4 it is worth a try. Gives you another reason to take the boat out for a long spin. My 95 starts each season with a quart in the tank. ------------- |

I've got a call into an injector place who will bench test for 20 bucks an injector. can't beat that. it's 45 total each if they clean them. I'll spend the $20 to test. Although if JQ's experience is typical... he's just gonna tell me they're pooched. Also everyone.... I just got off the phone with the boat dr aka billy sutton from Louisiana. The famous doctor himself. He's got a full take off pro boss tbi setup with pro tec ignition that was in running order. He wants low 4 figures for it... so I'm probably going to go with quick fuel m600 and DUI for about the same $$$$ if my injectors are pooched. This is great news for someone who wants to keep the injectors/pro tec. ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Just to keep things rolling...Synthetic ATF? Dino? Dexron III? Mercon? JQ Johnny, standard ATF not synthetic. I use the Dextron 3 because it is also used in my cars but I have read that the Ford ATF has more lubrication quality than Dextron. It has been used for many years to clean injectors, started with truckers using it to clean Diesel Injectors many years ago. It actually works very well to clean and lubricate. ------------- |

I am pretty sure the EPA would not endorse it but it has proven to work so we use it. Kind of like the 50/50 ATF and Acetone mix that works so well to loosen rusted nuts but is never sold over the counter at any store. ------------- |

| Probably 2-3 years back now I bought a rebuild kit for my throttle body. It had new blades, gaskets, o-rings, and regulator. I'll see if I can find the paper with the kit # tomorrow as I can't find the email where I ordered it. I believe it ended up being for a carb but worked perfect, I think I ordered direct from Holley. |

Yes...the uber-scarce Holley 250R-123AA injectors. I had a shop clean and test mine. One came back “dead”. I looked for weeks in vain. I called Holley and they tried not to laugh when I asked them for replacement injectors... Best of luck to you.

that's a good thought.. although where I'm from here in canada e85 is virtually unheard of. we do have ethanol blend but not full e85 readily available ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Hey guys, I had a really cool day hanging out with the injector guy. He tested the injectors and here's what we found. 1. We did a leak test. Applied around 60 psi of pressure without any power and we found that they were sealed up perfectly. That was a win to start with. 2. We did an inductance test. All of them came out fine as in "not dead." That's also a relief. The one issue we have is there's an injector that's stuck closed. Which is weird that it ran to 44 mph at 4800 rpm. Anyway... the test shows that one injector is indeed stuck. Which means it may be no good.... OR.... best case scenario.... it becomes unstuck in the ultrasonic cleaner. Thats yet tbd. If the ultrasonic cleaning fixes the stuck injector that's a huge win. If not... I'm going to have three benched tested, ultrasonically cleaned injectors for sale for $100 USD each ;) ... hopefully pay for a good portion of a quick fuel m600 swap. You guys should find out shortly. ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Thanks 2001sunsport for the heads up! Well we've got terrible news. My one injector is dead. Anyone have a 250R-123AA kicking around??? lol. If we can't source one on the forum.... I guess I'll do the retrofit to a quick fuel. Off I go to the parts wanted section! ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Quick question guys.... Do I need to run a mechanical fuel pump with a quick fuel carb setup?... or can I just use the low pressure pump that came with the pro boss Tbi injection. It's only 55 USD (almost 100 CAD after shipping and import fees). Small price to pay.... but you would think the low pressure pump would flow without issues. Thoughts? ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

Fuel pump for carbureted systems. I like fuel pressure between 5 and 7 psi. Per my fuel pressure/vacuum gauge, my Carter mechanical fuel pump produces 6 psi. I would counsel you to not use the low pressure fuel pump from the TBI set up. Go with a USCG approved mechanical or electric fuel pump designed to work with a carbureted system. Your old TBI system is also likely to have a return-to-tank fuel line. That return line needs to be securely capped off. Spark arrestor. My OEM spark arrestor that came with the ProTech TBI system did not fit on the QuickFuel carburetor. The reason for this is that the float adjustment hardware on the QF carbs does not allow the spark arrestor to sit flush on the carburetor mounting flange. I ended up going with a K&N spark arrestor/filter that has a raised flange so as to avoid the float adjustment hardware. Along with the K&N filter I purchased the K&N marine vent hose adapters for the breather hose and the mechanical fuel pump safety hose. If you need part numbers, send me a PM.

It is a marine rated low pressure pump and in its current use is only used as a transfer pump- I’d try it. Thought there were some PCM engines that used it from the factory with carbs but don’t have the parts book handy ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

| Any carb’d BBC from ‘91 forward and any SBC from 96 on has a good chance of needing an electric pump. Fords (carb’d) all had mechanical AFAIK. |

While Tim is technically correct I doubt there is really much difference between a GM using a Holley and an electric pump and a Ford using a Holley and a mechanical pump. Isnt a GM mechanical in the block as opposed to a Ford in the timing cover? I'm thinking GM changed the casting and or machining and the mechanical pump boss is gone requiring a different pump Here is a snip of the PCM GM page-  ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

yeah the black is a vinyl roll that was put on there. I haven't decided whether I remove it or not. The ski nautique is the ultimate facepalm. I have no idea where it came from... but I'd like to remove it completely. makes no sense. I mean...

Well crew here's the status of the Sport Nautique...... IT RUNS AMAZING. First and foremost.

We had virtually the same problems arise from our separate installs so he easily walked me through a stuck secondary float issue hahaha.

Hey guys here's a question for you. I only got to run the boat last year with a NFG injector and couldn't hit over 4400 (unless that was standard rev limiter for 1995 Pro Boss TBI. After the carb conversion... I tested to see how high the rpm would go. I hit 5100 rpm and it was still climbing. Did the rpm limit come from the EFI system before? I always thought that rev limit came from ignition. Thanks for the help ------------- 1996,1997 Sport Nautique 1986,1992 Ski Nautique - Sold 1995 Sport Nautique - Current |

What makes you so sure there’s a rev limiter at all? I wouldn’t expect one on the Protec stuff. I don’t believe the GT40 had one either. Let it spin. |

Thanks for the quick answers guys! It was just my assumption that there was a rev limiter. Every EFI vehicle I've driven had one. I gotta check the prop...

Prop looks like to be stock 3 blade OJ 14 x 16 cupped. Also have a spare Acme 1579 that came with the boat. (4 blade 13.5 x 14.25) Any recommendations as to which one would be better in the slalom course? I actually don't mind the idea of running out of RPM in the low/mid 40mph range.

Hey guys... I'm finally getting to where I need to look into Perfect Pass for this boat. In one of the photos above, you'll see the fuel inlet on the m600 gets in the way of where the servo cable would be on a typical Holley Carb Perfect Pass install. Would anyone have some wisdom on how they would attach the connector for the throttle cable/perfect pass adapter in order to provide clearance? It quite simply has to go downward. Would there be a problem attaching the "pull point" for the throttle cable/servo on one of the lower holes on the carburetor plate?
