Ah thank you! No telling what the previous owners and their mechanics did to modify (more like jerry-rig) it. I'll keep an eye on it once I get it running. If it doesn't leak, I'll worry about it later.
Now my crisis is the thermostat housing. Rusted really badly and they're next to impossible to find.

There's normally a 90 degree fitting there.
3/4 inch pipe threads on one end and 1 inch hose barb on the other. Some were plastic and some were brass A picture of each

Keno, Thanks for pointing that out. I was totally unaware that wasn't an original part. The other side is the exact same. I don't believe there's any epoxy there, although it looks like it in the picture. Anybody have any pictures of what it's supposed to look like? Thanks! |

Hi Rob
I had a 76 that I put a filter/separator on and I put it in the front left corner on a bracket that mounted to the stringer up high enough so access was relatively easy and it didn't interfere with the engine box... Can't help but notice that funny looking plumbing tee screwed into the front of the exhaust manifold. Looks like there's some epoxy around the threaded area too. I figure if it doesn't leak you might as well leave it alone since you might find hard to fix issues if you take it off. |

Annnnd another question: I know some of you have added a screw on type fuel/water separator. I'd like to do this but I'm not sure where to put it. Suggestions? I believe this would also work as a fuel filter, correct? When I got the boat there was an in-line fuel filter.
Here are some pics of my fuel pump area. The fuel line is currently not in place, as I'm in the middle of replacing it.

Can anyone confirm for me the plug gap needed for my engine with electronic ignition? I know the EFI engines require different plug gaps, but does the electronic ignition require different gaps?
Thanks! |

Quick update: My buddy is a shop foreman at a big local dealership's service department and he took my carb into the shop, took it apart and cleaned it in their hot tank and had one of his guys rebuild it (with the kit I supplied). Haven't gotten it back yet but hopefully good as new.
And a question: I'm probably going to replace my spark plug wires. The current ones don't look unusable but a few of the boots are cracked so I may as well go ahead and order some. Considering I have the Prestolite electronic ignition conversion, can you recommend a set of wires? The choices on skidim.com are not obvious (to a noob such as myself) which are the correct kit for my setup. I think it's the first one listed but want to make sure. Thanks! |

No reason [at this point] to suspect anything's wrong with it. Just trying to get a grasp on what I've got on my hands already. Received my new fuel feed hose and some other miscellaneous parts but haven't had a chance to put anything on yet. Got the carburetor off and it was full of crud so I'm going to have it cleaned and rebuilt by somebody who knows what they're doing. If I tried to, it'd take me a month... |

Rob,
Do you feel there's a problem with the EI? Ken is correct that the Prestolite EI is reliable. I have one in my 77. Yes Ken I ended up with an engine without points!!

That's the Prestolite conversion for their own Prestolite distributors.
It's no longer being made but they were a dependable setup |

My grandfather had this boat converted to electronic ignition several years ago. Is anyone able to identify the brand used?
   EDIT: Sorry for the sideways pics.... |

Luv the Rubber/Rope !!! I don't freak when I get close to the dock anymore.
But yeah, other models received the rope before the Nautique did. |

If you use barbed fittings and not hacked off metal fuel line you can safely use the rubber A1 hose from the pump to the carb.
That fuel filter isn't hurting anything. I have a 76 Southwind with a rubber/rope rub rail. |

If you wanted to keep the same fuel filter arrangement, you could put one of these in its place as you do the new fuel line. It's fine as long it's on the suction side of the fuel pump. It would be dangerous on the pressure side of the fuel pump.

It was added probably due to junk in the tank. |

Thanks! I'm hoping to have some time to work on it this weekend.
Can anybody offer any expertise on my fuel filter question? |

Sorry for 1000 questions, but currently there's an inline fuel filter between the tank and the fuel pump. It's located just below the midpoint of the engine so it rests on the bottom of the bilge. Was this added by somebody after the fact or is it standard issue? Is there a better type or place to locate the filter?

They probably have A1-15. It's a later version of the A1 that not only keeps the USCG happy but also the EPA. It's less permeable to gas vapor.
The A1 is being replaced with the A1-15. |

Thanks KENO! The hose one skidim is listed as A1, no mention of the 15. Should be the right stuff I'm guessing?

3/8 is the right size. 12 ft should be good.
USCG A1-15 0r B1-15 rated hose is what you want. The A1 is not much more expensive than the B1. They're both more fire resistant than regular automotive hose and is what you need to be USCG legal and keep yourself safer. You can't go wrong with the A1-15 link to fuel system requirements see page 72 |

Can anyone give me confirmation that the fuel feed hose I need is 3/8" I.D.? (Fuel tank to the engine) 12 feet should be more than plenty, right?

I didn't have to make any extra holes in the fiberglass, but poked a lot of holes in the rubber to match the existing holes in the fiberglass. According to the brochures in the reference section the first year was 1979. I remember it like it only happened about 38 years ago |

lots of you tube videos on rebuilding Holleys. I think if you have a pulse and a desire to rebuild one, you can probably do most of it without help. There are a few things that will get you, but if you lay everything out in an organized way, and go through the process meticulously, there aren't many places that will hang you up. There is a special clutch bit screw driver blade that you will need to remove the secondary metering block, and Holley recommends a jet screw driver instead of a flat blade for removing/installing jets. the rest is just labor, lots of scrubbing and blowing out of orifices with compressed air. you need to soak carbs in a carb cleaning solution to get them clean, so invest in one of the bucket set ups from your local auto parts store.

Interesting, my 76 Martinique has the rope rub rail. From the inside I cannot honestly see any extra holes through the fiberglass. Art may know if it was available at that time.

Anything else you guys think I should check/replace right away? How hard is it to remove the fuel tank? There's some debris (and very old gas) in it so I'd like to clean it out.
