Edelbrock Marine , I'm and Old School Holley guy , But the Edelbrocks are by far the best for a bone stock pleasure boat app. We've installed probably 40ish
on everything from Ski Nautiques to 30' Scarabs , and haven't had one complaint or issue in 5 years.

Thanks so do you think if I went with a 750 do you think it will help me or hurt me?

the gain from 715 to 750 cfm carb would depend on the carb itself,not all 750s are created equally.imo the gain from a good 750 will probibally not be worth the cost for a stock 350.

Best bang for buck is rebuild the holley you already have.

I don't think you will notice much difference on a stock 350.

Not to open a can of worms, but mathematically, on it's best day, a stock 350 only moves 506 cfm of air at 5000 rpm, assuming 100% volumetric efficiency - which will really never happen.

If it was me, I would keep what you have, rebuild it and be happy; unless there is some major performance issue with it..
