Im almost all the way through the tear down proccess right now. Tomorrow I will be washing out the hull and prepping everything for the "beast" to go back in. Heres some of what Ive captured so far. I have no one to be snapping pics while Im working so forgive me if there are gaps in the progression of pictures.
There a little charred but its all at the machine shop now. 
These are all my goodies so far....More to come!!! ------------- "Some people go an entire lifetime wondering if they made a difference. Marines don't have that problem" -Pres. Ronald Reagan-  |

I read all the threads on heads before I made my purchase and it seems to me that I will be ok with raw water on aluminum heads. Especially if I flush the system periodically.

Now your question kind of confuses me. A Standard Rotation Boat - Spins left (counterclockwise) when looking at the the prop from the back of the boat. - Spins right (clockwise) when looking at the flywheel from the front of the boat.

Not my intent! 
I understand RH and LH...you guys cleared the terminology up for me a while back However it's put, both my boats were RH...opposite a car...clockwise facing the stern Backfoot asked if he was converting to standard rotation. I took that to mean going from RH to LH. I asked because I thought all of the older CC's were RH. ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

Get the camera out again, give us a good shot of the dist. drive gear or a shot of the prop.Either one will tell the direction ,LH or conventional/ RH reverse rotation.
Some the parts you have bought will work.The rear seal is specific to rotation,as is piston rotation.The cam is a LH, or convetional,and will not work with a RH or reverse rotation dist. The oil pump is the same for either rotation. Hope you did some research on direction before you jumped into this rebuild...boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

The block is at the machine shope right now, and taking into account the shape of the cylinders and the pistons I will not have to do any boring at all. But if that situation presents itself I will keep you in mind. Guess I started quite a thread with the rotation comment. I know my boat is a standard rotation motor for sure.

No the pay still sucks. My mother passed away a little over a year ago and left me some money, so I am going to name my SN after her. I purhcased the boat on exactly the day she passed away. See she taught me how to ski when I was little and she was an amazing skier herself. I figured its the only way for me to spend time with her now that she's gone. ------------- "Some people go an entire lifetime wondering if they made a difference.

Sorry about your Mom, and congrats on doing something to remember her.
I'm not sure how you are positive that it is standard rotation, double check and triple check that this is the case. Are you just going to put rings in it if the cylinders check out? What is the chamber size on the RPM heads? 750 is too much carb for the 351 in a ski boat. 351 ci. at 5500 rpms, with 100% VE (volumetric efficiency) is only 560 cfm. I'm suprised doc didn't jump on that. What kind of lift, duration and overlap are you running? Solid lifters, I guess you like adjusting valves. ------------- Every day above ground is a Good day.

Intake duration of 291 and an exhaust duration of 311, intake lift of .541 and exhaust at .526 and a lobe seperation of 107 deg. which means I am safely clear of the 115 deg no no zone. I do however understand that my (VE) is at about 134% at 5500 rpms with the 750 carb...BUT I will be spinning faster than that. More to the tune of 6000. The (VE) of 134 is with the carb spraying static. So with the carb bridled a bit I will have no problem getting pretty close to 100% (VE). No I dont mind adjusting valves and with the limited time the boat will be in the water the adjustments will be minimal. Besides it will grab RPMs alot faster than a Hyd-Lifter motor. ------------- "Some people go an entire lifetime wondering if they made a difference. Marines don't have that problem" -Pres.

racintj, did not chine in on this issue as i was not going to be the one to piss on his parade.
The cam and induction system will work great for a 1/4 mile car running 4.56 gears, for a short time .But soon MR. Squeeky will come to call,bottom end failure. I see lots of issues,rotation I am not sure of,cam too muh bump,carb too large, incorrect rotating assy.for said RPM's,and largly understanding how a boat engine works VS car motor immense. But the proof will be in the pudding. If he can prop it afterward that alone will be a story for this site. If my prop math is correct; If the motor will pull a 13x14 /6000rpm's =68mph that will be a fast C/C....good luck..boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Doc He will never get 68mph out of a nautique. He will have to prop it down if he wants 6000 rpm . He may need a 13 x 13 or maybe even a 13x 12 1/2 . Is that the acme 541?

Ive heard that for some reason on the RH rotation that the pistons need to be installed backwards with the notch that is in the piston pointing towards the back . Look at thepistons again and check it out .
I dont know why . Its just what Ive heard . I just noticed in your 5th pic that the notches are going to the front . ------------- Pat http://i175.photobucket.com/albums/w146/72ccfan/100_5977-1.jpg - My 72 Skier Rock River Dixon,ILL. |

Marine, don't take this the wrong way, keep your head high and take the punishment. I think the majority of us have had to suffer thru it. I know I did. Really, you need to take into consideration the info given. I have built many motors that go in fast cars and race cars, but I still didn't understand many characteristics of these boats and motors. It will be pretty hard to turn that motor to 6000, especially with the stock bottom end. And if you do turn it, it will be about 1000 wasted rpms. As doc stated, the efficiency of these boats and props drastically reduce past the 5000 rpm range. I also doubt very seriously that you will have a VE of 100%. You may prove us all wrong and make a 70 mph ski boat, then we will all eat crow. We all know that torque and HP always equal at 5250 rpm, so build a motor that has 300 ft/lbs of torque buy 2000 and keeps increasings to 5000, have HP and torque meet at 5250 with 400/400 tq/HP...that my friend would be a happy boat. ------------- Every day above ground is a Good day.

MarineSRT8 / Nate,
Before you get too carried away with the motor work, please go inspect the prop on your boat. You have a reverse rotation, RH motor in the boat. This was STANDARD in the 80 SN. By reverse rotation, we mean OPPOSITE of a car. Not wanting to add to the argument, but go look at your prop, it will tell the tale! I should know, I used to own the boat you are working on, I sold it to the man you bought it from.....and I have plenty of photos of it, one showing the prop and the fact that it spins RIGHT to propel the boat forward. As stated earlier, this will make a difference in the parts you have purchased. pc ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=3448" rel="nofollow - 1973 Ski Nautique http://correctcraftfan.com/diaries/details.asp?ID=830" rel="nofollow - 1979 Barefoot Nautique |

First of all doc you are hilarious. And all of you guys are awsome!! You have all given me info that I would have not recieved anywhere else. Yes I do know the boat was a RH at birth but I am going with the 1.23:1 tranny and spinning her the other way. I figured that tranny would give me a little more room to stretch her legs. My last post of yesterday was not to downplay anyones konwlegde. I do understand an engine spinning a prop and and engine spinning a rear end and tires react very differently in many situations. Keep coming with the info and posts though its all keeping me motivated to stay on top of the project.....and by the ay Doc, I laughed out loud by myself at your post.....pretty funny ------------- "Some people go an entire lifetime wondering if they made a difference.

Glad to know you are on top of it. I will tell you though, it seems you are going a long way and spending plenty to NOT rebuild the bottom end. A fresh set of slugs (hypers that MM has for sale), ARP rod bolts, polish crank, and hone the block wouldn't be more than a few hundy.

And with that heres a few for to keep everyone updated on her progress. Hey look factory interior hiding under there!!

Marine, I just thought of something that hasn't been mentioned in this post, and I don't know if you are familiar with. Make sure you tell the machine shop that you need piston to cylinder wall clearance to be double of a street motor. There are threads on here that talk about this, and many bad experiences of motors that were built by reputable street builders. Motor always under load (pistons heat and expand), block constantly cooled by lake water (stays cool, less expansion) = more clearance needed. Good luck, just thought I would try to help. ------------- Every day above ground is a Good day. Lakeland, FL |

Hey, Scott, Good to hear from you. I was just thinking of you the other day. Maybe you've been posting and I've missed them. But I was thinking just because you had to ease up on the fiberglass and paint work, that I hoped you werent going away. I still think that torino you did is one of the finest boats on the site, although I am partial to torinos. Do you keep in touch with the new owner.

The 123 will allow her to squat, grunt and sprint a short distance quickly with lots of authority, while a 1:1 with a smaller dia/higher pitch prop will typically make the most of a higher rpm engine, i.e., most speed in a lighter boat. If your cam is the only direction-specific part you've bought, then RR is still your best direction in this hull. At least CC thought so, and I know you've probably heard or been told that it will list to starboard with a LH engine. It will. As for RPM, it'll turn what it can with a 13x13 or 13x14 depending on prop design/brand. By that I mean you won't prop it with the intentions of making it get to 6K, but more so prop it as you would with a typical 350-351 ci engine. Then let the cam, heads, and other mods take it from there, and see just what it will turn, 6K or whatever with a max of around a 13x14 prop. THEN step up the prop (more pitch) and see if you can lower r's and gain speed, and thus find out what your combo's sweet spot is for making the most speed. Even though this pkg would want to turn 6500-7000 thru the gears in a car to get the max in terms of 1/4 mile acceleration, in a boat for max top speed the ideal rpm is typically somewhat reduced down towards that HP/torque intersection racintj mentioned. In the meantime thanks for volunteering your efforts and funds as our newest guinee pig. It'll be fun for all of us...............until next year's reunion. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |

none of those lakes are in North Webster, and I have never heard of a Marine lake anywhere in IN. so the right answers would be webster or backwater lakes as they are the only ones in town, the barbie chain is south, tippy is south east, dewart is further east than tippy, and wawasee and syracuse are in another town. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

SRT8...I like the boat, and what your getting into, its going to be fun and very rewarding. That Intake looks like a proformer, max RPM is around 5500, and I dont think that gear drive is the right set up for a marine motor, not only is it going to be very noisy but it will also create harmonics which is not a good thing for a boat! but with all that being said if you can get the HP up to about 400hp you should have a 60mph boat.. and then you will able keep up with me...keep the pics coming! ------------- |

Mark, just as Lisa thought she originally saw a Performer in you and in reality was looking at an air gap, so have you. Based off Marine's part no, he's got an AirGap Performer RPM which works right on up to 6500, so I'd say he's good.
Marine, I hope my comments don't come across as overly blunt. Sarcastic sometimes, but hopefully never demeaning. As for speed in that vintage hull, on average 300hp is typically good for a little better than 50, 350hp will probably net you 55-57, and I'd bet 400 will get you that 60 and maybe a few more, but that's just my good educated guess, as I'm accustomed to running a smaller hull where 300-325'll get you 53-56. Still working on the 60 mph goal. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |

And don't for get about upgrading the dash as the stock tach only goes to 6k, but the exhaust sounds pretty cool spinning the motor that fast.

That many rpms on that length of hull should make it porpoise. ------------- Tim D |
Posted By: reidp
Date Posted: September-04-2007 at 11:59pm
Tim, I wasn't sure if you were saying that's good or bad, but for the sake of speed with this boat, hopefully it does porpoise, or at least have the tendancy to bounce and keep the bow high. A boat that keeps the nose high and tends to porpoise is a fast hull and can be corrected to minimize bounce, but a hull that buries the nose is limited and a handful. Depending on the amount of hook in the hull, esp in boats like TimD's and my first gen Mustang hulls, the faster they go the more they plant the bow and can get uncomfortable/unpredictable at high speeds for which they weren't designed to go. I've addressed the hook slightly on my 69 Mustang which is the only reason it would run slightly faster than BoatDr's boat which has more HP. Oh, and he had those trim tabs turned down, I guess 'cause Karen was in the boat. I'd bounce Laurie onto the bank for a half mph. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |

Reid, tho i have not had the time to devote to the all out speed, I to am slowly tweeking.
The 27A rudder was a major plus ,no more pull or drift at the 50 mark. Cutting the prop shaft was a plus also. The rudder port mod. was a little less drag too.Have not GPS'd her since the latest mods but she seems stronger and much more controlable. SRT8 don't wont nuttin' to do with a 60mph CC,mine is a handful at 53+ add 7 to that ,not...........boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Billy, Srt8 's boat is a good bit longer and quite a bit heavier. 60 in your little rig would be hairy ride but if you could get the bigger nautique to run 60 it might be a thrill but I would think managable. I think 60 is a little bit of a stretch but it'll be fun for everyone to see the progression from what he's got now. Plenty of pics please. ------------- You can’t change the wind but you can adjust your sails |

I believe it's referred to as S.I.P., aka Shi* in Pants. No wait, that's when you hook the chine at high speed or upon quick decelleration and it either turns without you asking, OR refuses to turn when you crank the wheel. Both are scarey and traced also to rudder conditions. As far as the planting the nose of the hull firmly, I don't know of a term as many normal people might look at this as a virtue. Only when stretching it out beside his buddy's oscillating hull and getting outrun does it become an issue. A quick (as I can make it) related story, my orange and white '73 Mustang has always run pretty strong (50-51)for a stock boat. Years ago I noticed that often it would get up to top speed for just a second, and then all of a sudden fall off about 1 mph and drop 100rpm. I chased what I thought was an engine problem for 2-3 yrs before I realized that it only did this once the slight bounce stopped, and that it never happened with several persons in the back seat. It's like you can actually feel the point or moment when the water sucks the hull back tightly to the water, significantly increasing the drag. Later hulls which hardly raise the bow while planning don't experience this. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |

The SS is attractive but looks a little on the cheap side for a "Super Sport"....I agree with phat the Jeep is a way better spend of your money. Im not exactly sure what the SS goes for but when I bought my 300C SRT the Jeep was going for about 4 G's less and I spent a hair less than 50,000 ------------- "Some people go an entire lifetime wondering if they made a difference.

YES it is! Its a iron block GM 6.0L truck motor with PCM fuel injection. I take it the ZR6 motor is standard rotation correct?
GM has two versions of the 6.0 in a iron block LQ4 low compression and the LQ9 High compression. The LQ4 is cheaper and easyer to come by. ------------- So what winks and f**k's like a tiger? www.facebook.com/sabre002 |
