Hey everyone, newbie here. Just picked up an awesome 1965 with a 289 that the previous owner says was bored out to a 302. I am NOT a mechanic by any stretch. I can change plaugs/wires/cap/coil etc, and do an oil change. But when it comes to diagnostics I am lost. It starts great runs great at lower speeds, say in the 20s. After about 2500 rpms if I hit try to punch it wide open, it starts to fight me, bogging down and if I let up on the throttle a bit, she will run fine. The carb seems super clean. Question, is there a fuel filter on here? If there is, it must be back by the gas tank because I see none following the fuel line to the motor. Would suck top have to remove the rear seat to get to the tank. Really sounds like a fuel issue. Maybe the 1/2 tank of gas that was in there when I bought it has been sitting for a long time. The old man had only been taking it out now and then to run on his driveway. Also has a slow tranny leak, but I do not think that is causing me the bogging down as I checked the fluid when warm, and it still had enough in there to run properly. What would you guys recommend that I add to the fuel to see if it can work itself out? I did fill it up the rest of the way with fresh 93 octane gas. Please help. Was thinking plugs and wires too maybe, but if they were bad, it wouldn't start so easily and run so well at lower rpms. I don't think! I appreciate any advice before I have to bring it somewhere and get raped! Glad to be part of this group. Love the boat, he did a nice job restoring it. Jeff |

 Is this the fuel filter on this motor? I see the fuel line coming into it, and then another leaving it going to the carb. |

Congrats on the boat! The picture above would be your fuel pump. Not sure if those boats had a fuel filter. Hopefully someone with more experience will chime in. ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

| Thanks, just realized that it the pump after looking at other sites. I did find the filter as it hooks directly into the carb. Pulled it out and it looks recent and seems ok, but for the few bucks, will change it since I already have it out. Does my bogging down issue sound fuel related? Can it be the pump or would it give me problems at lower rpmd as well if it was bad? Can you recommend a fuel additive to try and put through? Thanks for your help. Sucks being new to this and feeling stupid! |

Never feel stupid, that's what this site is about. I am too an inexperience boat owner. Seems like you are getting fuel, if you know, was the carb ever rebuilt? I had similar issues when I engaged into gear but it killed the engine. Had carb rebuilt and runs great. Good luck ------------- Kostas http://www.correctcraftfan.com/diaries/details.asp?ID=6700&sort=&pagenum=1" rel="nofollow - 1984 Ski Nautique 2001 |

| The carb was rebuilt, he put a 2 barrel on it to save on fuel. Still has plenty of power. Looks clean as heck. Not sure why she is fighting me at full throttle but not at half or even 3/4. That was why I thought maybe adding something to the fuel would help, but I am not sure what to add. Like I said, the old gas may have been in there for a while. But why probs only when I want to go faster? |

First of all we need pictures  If you have a timing light you could see if the distributor advance is working. For a fuel treatment you could try Seafoam,it has worked for me with yard equiptment. As to a 2bbl saving fuel I have heard that,not sure it's true. If your not into the secondaries I think a the primaries on a 4bbl would be smaller than a 2bbl thus saving fuel over a 2bbl ------------- 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 |

That looks like an automotive fuel pump and rubber hose going from the fuel pump to the carb. The pump needs to be replaced with a marine and that rubber hose needs to be replaced with hard line. None of the above are causing your issue, as pointed out by Gary make sure it is timed properly and that the advance is working and then move on to the carb. ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

Pleas post a picture of the carb. If the fuel pump isn't up to code, possibly the carb isn't either. If you have to replace it, go with a 450cfm 4 bbl marine Holley. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

| I will get a few pics in a few min, if I can get the baby down for a nap! UGH! It was just suggested to me by a guy at Autozone to replace the mechanical fuel pump with an inline electrical one. They have one for a 289 for only 42 bucks. Is this advisable? |

NO! You need a http://www.skidim.com/prodinfo.asp?number=RA080002A" rel="nofollow - marine fuel pump , this may work but you need to make sure. Also you need http://www.skidim.com/prodinfo.asp?number=RA085002B" rel="nofollow - hard fuel line such as this. You do not want fuel being pumped into the bilge, it is very dangerous! As Chris suggested we need to see a pic of the carb to make sure it is marine specific also. http://www.n3boatworks.com/" rel="nofollow - N3 Boatworks is another good source for parts, CCF members get a discount! ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

I have to run out,I'll look later and see what the settings are supposed to be. Anyway that is the original type Ford carburator for that motor. Actually a pretty simple one that never gave me problems other than not starting as easy as a Holley. Not technically a marine carb,it was way before they were required. I think Vondy and I,who both have Holman Moody's are the only regulars who have had these carbs. I think he changed his too,I have a 450cfm Holley and a 600 to try sometime. That part on the carb where the hose clamps to is a fuel filter but I think that was added later. ------------- 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 |

Hey Gary who manufactures those carbs? He says the PO put a 2 brrl on it, so is that the original for that engine or should it have a 4 brrl? ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

Jeff thats a Autolite/Motorcraft depending on the year. Ford had gotten into trouble with the govt and had to sell the parts division,then turned around and started Motorcraft. I don't think it will be a carb problem they are really simple, no power valves etc. I would never have added to the old gas,but that is done. Change the filter if you'd like put some Seafoam in and check the timing and advance first. Should not have a check valve on the tank outlet but you never know if someone added it. If this fails you might have to check fuel pressure and volume. ------------- 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 |

| It seems that based on what some of you have mentioned, I should change the fuel pump and lines regardless of whether that is causing me my problems or not. I do not want to put myself or my family or anyone else at risk of explosion. From what you guys have said, the automotive fuel pump and rubber gas lines are very bad. Would be great if the fuel pump ended up being my issue since I will likely have to change it anyway. Thanks for the help everyone by the way, really nice group. |

Thanks for the info Gary! Yes Jeff you need to put a marine fuel pump on , it has a dual diaphragm so if one ruptures it will pour the gas back into the carb via a clear tube. If you see fuel in the clear tube it is time to change the fuel pump. Also you need a hard line on the pressure side of the fuel pump to the carb, you do not want that rubber line to rupture and punp fuel into the bilge! ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

Yes, on the supply side to the fuel pump rubber hose is fine. ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

| Also, after I purchase a new fuel pump, how do I know which hardline is the right one that will fit perfectly for that specific fuel pump to my existing carb. Obviously the line is preformed and cannot be bent to fit. Will the 2 items that cphase linked me to work for that pump and my carb? Thanks again! If so, I will order them. |

Jeff..cant say for sure on the pump, that is for 302/351, you need to check. I would say no for sure on the hard line, I am not that familiar with the engine you have. Gary said he would be back soon, he is more familiar as I believe he has the same setup so he can answer your questions. Sorry I cant be of more help right now! Good luck, keep us posted and let us know what you find. ------------- Thanks, Jeff http://www.correctcraftfan.com/diaries/details.asp?ID=6549" rel="nofollow - 82 SN http://www.archlinux.org" rel="nofollow - Arch Linux |

First off you won't find a prebent fuel pipe for that antique,most would make up one from a brake line and bend it and maybe cut and reflare to fit.I don't use that carb anymore but mine had rubber hose too. I have switched mine and used a AN stainless braded hose which I understand is not Coast Guard approved either which is ironic because a AN hose is a hose approved for aircraft and stands for Army/Navy. As to the fuel pump just get a marine one. A commom misunderstanding is that all marine pumps have a double diaphram,some do some don't it's just a design difference,but all do have a fitting for the clear sight hose that goes to the arrester. What you do need is a pump that the fitting exits to the front,a rear exit will hit the oil pressure extension. Since my engine didn't have a sight tube there was nowhere on the arrester to connect one so I made one. I used some brass sheet bent it to fit and soldered a tube on to connect the hose to. Here are some pic's     And the last tease picture,you can see how I routed the various hoses and you can see why finding a prebent pump to carb hose would be impossible to find since a Holley is more common than that Ford carb. A 2 bbl Holley would have the inlet in the same position as a 4bbl. If and when you decide to change the carb I personally would not bother with a 2bbl but would go with a 4bbl manifold and carb. Remember that just because you use marine grade items don't close the cover and ignore it,open it before the first start of the day and after refueling and use your eyes,nose and blower. 12 degrees at idle and .020 points will get you started.  ------------- 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 |

That is a manual choke Tim,just like mine in this pic when I first got it,mine was rusted and didn't work.

Choke cable, well that was missing on my Mustang when I bought it. I don't think it had an electric one on it either. That Motorcraft carb has been on the shelf for a long time, now has the 3rd Holley on it. Don't get sticker shock when you buy a new cap, it you have the flat top Mallory, those things are expensive now. ------------- Tim D |

Jeff, I've been gone for a week so forgive my late comments. I understand you are not a mechanic but also understand the the PO you bought the boat from wasn't ether. He was truly a "back yard hacker"! Stick with all the comments others have made and understand there are some big differences between running to the auto supply for parts and truly getting marine equipment. The hard pipe from the pump (marine pump of course  )is going to require some bending as mentioned but worth it so you are not boating in a BOMB!!------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| So I changed the plugs and wires yesterday. Put in Motorcraft Copper gapped at 35 and she is purring. Still want to change the cap, rotor and points. Finding these products has been VERY hard. I think I found the right cap here.. http://www.amazon.com/Prestolite-9-29416-Flat-Marine-Distributor/dp/B0060LJPJU/ref=wl_it_dp_o_pC_S_nC?ie=UTF8&colid=2U8859YJRTBCB&coliid=I2FIB6N04TP0A6 but I can't find the right rotor anywhere. I have looked through more images than I can count. Havent even started to look for the points. Anyone now where I can find the rotor and points for this thing? |

Jeff it's more important to show and tell us what distributor you have than showing us parts the the PO might have gotten wrong. Get us a picture of the tag on it's front. Does it look like mine? It is a Mallory YL. I also would advise you not to buy on Amazon,I don't know how the return policy would be. Summit Racing is where I get my ignition parts,they are fast shippers,have the items in stock for a decent price and take returns with no problems. ------------- 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 |

Just ordered this from Amazon. Before I read that last post! But is was the only place I could find a kit. Plus we have a Prime account and they are very good with returns. Here is what I just purchased: http://www.amazon.com/gp/product/B00027GM0I/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 The Mallory Distributor says type Y on the front plate. I hope this kit is what I need. |

| Will post pics of our pink boat shortly...lol..previous PO painted it pink after he lost his wife and daughter to breast cancer. At first I was like, a pink boat? But then it did hit home, as I lost my Mom to breast cancer as well. So I am leaving it pink and making it a tribute to my Mom with some pink breast cancer ribbons, a loving memory of my mom decal on each side of the boat, and the name LIVE FOR TODAY on the back. It has attracted so much positive attention already and I dont even have the vinyl decals on yet. Would lke to make it a vintage 1965 Breast Cancer Awareness boat and maybe take to some shows. Needs a better pink paint job though. Wonder if a local shop would sponsor it and paint it for free and allow them to paint their name/logo on each side of the front of the boat. |

That is a very nice pump,one I have by the way for a spare. The problem is that the sight tube connection that tells you that the pump has an internal leak faces to the rear of the engine and hits the oil pressure extension. ------------- 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 |

| Been learning more, my Interceptor motor has the following number - GT21R525971, which if the info I have been finding is correct, means that I have a 260, not a 289. Does that mean I need a different fuel pump? The PO said it was a 289 bored out to 302. What the heck do I have and how do I find out?!?!?! UGH! |

Cannot tell by the picture if the cap is good or not,many now days have aluminium terminals the good ones have brass. Does your distributor tag just have a Y on it or is it YL? Your boat I believe has been on here before,but I can't find it as of now. ------------- 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 |

Same fuel pump for 260, 289 and 302. Intake and heads swap with all three too. Check the casting numbers. C6 is '66, C5 is '65 etc. Mine had a 65 block and 64 heads originally. You can get the cap at NAPA, tell them you want to see the marine catalog behind the counter. The box mine came in has MA1 on it. ------------- Tim D |
