Much to my suprise, I don't have a Holley Carb on my '84 SN/Commander Engine. It's Either Weber or Edelbrock (same thing?). There's an Edelbrock sticker on the carb but "Weber" is cast into the carb. It looks like the carbs on the Edelbrock website rather than the pictures of the Webers I've seen.
Did Commander use Edelbrock or Weber carbs? The guy I bought the boat from was into "high performance" mods for his truck so he could have very well slapped it on. Who's our resident expert on Edelbrock Carbs? |

Does the carb have a bunch of extra vacuum ports like an automotive carb? Maybe it had a Holley and the guy threw a carb on from his truck? ------------- 1975 Ski Nautique "Small Letter Boat" |

Edelbrock Marine carbs are much cheaper than Holley's and that's probably the reason the PO put it on the boat rather than the original Holley. Edelbrock's a simple carb and generally give good fuel consumption. ------------- 64 Skier 66" HO VTX and 67" HO Triumph http://www.correctcraftfan.com/diaries/details.asp?ID=1071&sort=&pagenum=3&yrstart=1971&yrend=1975 - 71CC |

It is in fact an automotive carb. It's got several plugged vaccuum ports . Also, I found a number on it. It's an Edelbrock Performer 1406.
What are the differences in a Marine vs Auto carb? Should I replace it right away or wait until it craps out? Then, with what? Edelbrock Marine? Holly 4160? Something else? Given my limited knowledge of carbs, simple is better. And because I'm a tight ass, cheaper is better 
64--by good fuel consumption, do you mean poorer fuel economy? |

I have an edelbrock/weber carb, I believe edelbrock bought the design/tooling of the weber carbs (they all still stay weber in the castings). I am very happy with mine runs like a top. Differences between marine and automotive are mainly safety related, (besides some changes in jetting and pump springs which can be duplicated with a strip kit if you feel like it isn't smooth enough or your too lean/rich. Marine carbs are required to have provision to dump excess fuel into the engine in case of flooding. Auto carbs dump it over the side, a problem for boats where gas fumes in the bilge can lead to a boom. The 1406 is the automotive electric choke version (600cfm) that is jetted out of the box for fuel economy. The marine equilivent is a 1409. Unless your real strapped for cash I would be thinkin about replacing it soon, and until then I would keep my eye on on it for leaks, make sure the floats are adjusted well, and make good use of the blower before starting the engine and while idleing about ..

I would just find a Holley 4160 somewhere. Maybe Ebay if you can't find the above mentioned free carb. They are more simple than the edelbrock. J Vents and special shaft seals make a marine carb out of an automotive one. ------------- 1975 Ski Nautique "Small Letter Boat" |

Thanks for the info.
79-- there are 2 people ahead of me for the free one. Are Holleys easier to work on (rebuild, adjust, keep adjusted) than others like Edelbrock and Carter? |

Don't ever say carter again bad bad....not very familar with them, dad's comments back in the day was, they where pretty inovative but never could get to work quite right.
IMHO the holley's are easier to re-build, they have fewer parts and aren't as complicated, unless you have a high end model that is very costumizable. but you have to adjust it more often to keep it running right. The q-jet, (edelbrock or rochester) are harder to re-build, more part's, small parts that are easy to bend while putting it together, you have to bend linkages to get it adjusted correctly, the float isn't as accessable to adjust but you don't have to realy change it once it set at the right hieght. Once the q-jet is set up on the engine and adjusted correctly you realy don't have to touch it again maybe a little idle adjustment and the idle mixture screws once a year and your good to go. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Edelbrock/Carter AFB's are a bolt on and go product, require much less adjustment than a holley to get running and stay running right. I also found them to be much easier to rebuild than holleys, but to each his own there. The main difference with the edelbrock is that if you want to get into custom tuning (typically not required but some of us can' t keep our hands off things) it is done with fixed rods and jets that you must go out and buy (you can get a kit for about 25 dollars). I liked this method of tuning as it gave me discrete steps, so if it was too rich I could go one step leaner, personally I was never all that discrete with the Holleys, (was that half a turn left or a quarter turn right, I dunno start over). I however have no doubt that someone who knows what they are doing can probably get a little more out of a holley on the track than an edelbrock. Its personal preference but I don't buy the arguement that the edelbrocks are more difficult to work with in the automotive world they are considered the easy alternative... ------------- 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 |
