It's getting warmer and time to do some work on the old boat. I have a 1987 Ski Nautique with 351w (of course.) I have a lot of trouble getting it started It runs well but I have to crank and crank to get it to start, especially after its warmed up. I'm assuming I have an automatic choke in the carburetor? Can that be adjusted? Other than that the only thing that it does is hesitate to come off idle. If I give it too much gas too quickly it will die. Runs great under load. Idles great. Thoughts? ------------- Never miss a good chance to shut up ~ Will Rogers |

I'd suggest rebuilding the carb. ------------- /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 < |

My carb is an Edelbrock 8867. Is that the correct carb? ------------- Never miss a good chance to shut up ~ Will Rogers |

Cy, The original carb would have been a marine rated Holley. Sounds like a PO has been messing around or really didn't like Holley's!! I googled the Edelbrock 8867 and it's not even marine rated. That is a potential hazard. Many here have been installing Quick Fuel carbs with fantastic results. I'll do some searching later for some links to threads. ------------- /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 < |

Don't believe everything Pete just said  The 8867 is a casting number found on a whole bunch of different Edelbrock carburetors. The model number is found on the front of the right front mounting ear. Here's a picture of an Edelbrock with the location shown. The one in the picture is not a marine carburetor but shows where to look for the number. You should find a number there that has 1409 or 1410 or 9910 as the first 4 digits.if it's marine. If you find other numbers like 1405, 1406 etc then it's not marine.

Cy, I'm glad Ken stepped in with better knowledge than I. Thanks Ken!  ------------- /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 < |

Here's a link to some info. Not huge differences, but enough to minimize your chances of having a fuel fire/explosion because of external carb leakage. The 1405 also was quite a bit cheaper because it had a manual choke, although an automatic one could be added to it http://www.cpperformance.com/c-1099-edelbrock-carburetors.aspx" rel="nofollow - link |

Functionally the same and use the same base cast pieces but there are definite marine specifics. Generally they have a marine external coating that protects better in a marine (wet) environment and have a threaded fuel inlet, not a nipple for a hose w/ clamp connection. Also, you'll find the jets and metering rods are different from the automotive to marine versions and if memory serves, a different bowl venting system. All together a marine rated carb will considerably lower chances of fire/ explosion due to leaks or gas venting and is set up (metering, etc.) for the different loads and stresses that are specific to boats and different than that of a car. ------------- JCCI 1995 Ski Nautique GT40 |

Sounds like you read the link in the post before yours Joe and then spit back some of the Edelbrock marine info If you didn't, then you should, since that tells a little more |

Off the top of my head Ken ... First boat was a carb'd Mercruiser that ended up with some carb issues after a tank full of terrible fuel. It was rebuild it or replace it so I did a bunch of research and ended up with the 1409, which ended up needing a few tweaks to work correctly with my engine, hence the extended research. Mercury used their 'own' carb which was basically an off-the-shelf Webber with some of their own tweaks. Funny thing was Edelbrock did the exact same thing ... utilizing the exact same model of Webber for its platform. Go figure ....  ------------- JCCI 1995 Ski Nautique GT40 |

OK I may have an electric choke problem. When I turn the key on have have 10.8 V on the electric choke, but nothing moves. Also nothing moves when I turn off the key, and I don't hear anything trying to move either. How is it supposed to work? ------------- Never miss a good chance to shut up ~ Will Rogers |

Cy, The choke should be almost closed when the engine is cold. Then, when you apply power to the choke, the bimetallic spring that's under the round cover starts to heat up. As it heats, the choke should start to open. This may take several minutes to fully open. ------------- /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 < |

you can adjust choke for warmer weather, open it some more or colder weather, close it some. If it was me I would run NO ethanol gas and dump in the right amount of seafoam into the tank and run it. Also time to go through the whole thing, Cap Rotor, plugs, if you have points then replace etc. Make sure distributor is working properly etc, when you are working on anything never stop at one problem because there will typically be multiple. |

Your symptoms are classic of a carb that drips gas while off due to improperly adjusted or gummed up floats or float needle/seat. the question is whether you want to bother cleaning up and dialing in a carb that is less than ideal and may blow you up or if you would rather invest in something marine rated that will likely not need so much messing with. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |
