I have a 1974 20 ft Reinell with a 305 OMC 225hp drivetrain!! It currently has a Rochester Quadrajet on it. I dont think it has ever been rebuilt since 1974. It has been sitting for about 3 years now. I just went and took it out on the lake. It doesnt seem to stumble or anything, but I am just wondering if I could get a little more performance out of something else. My buddy has a Holley Carb on his 85 Suburban (350 motor) that he says I can have. Which carb would be better suited for my boat!! I need a little more power!! Any help is greatly appreciated!!!

Re: Carbs- Rochester or Holley

since the Rochester has worked all these years<br />without ever being rebuilt, why change?<br />give specific info about rpms, prop, hull etc.<br />and maybe the guys here can tweak the set-up 4 u.<br />if it ain't broke, don't fix it!<br />my .02,<br />M.Y.

elknuts- :( if your motor is in a closed motor well DO NOT USE a standard automotive carb, marine carbs have a closed vent system, automotive carbs dont fumes can build up in your motor well and can& will explode :eek: there of plenty of marine carbs ava, for your motor though aftermarket supplers etc. holleys and others Be safe not sorry ;)
