As always, thanks for the input. I may step up to a 750. Tunnel ram is out, if you knew the type of skiff you would see why. Besides it wouldn't fit under the hood!!

You can up grade your 650 holley to a 750HP using the Holley or Proform
HP 750 carb body kit. It works very well and is well worth it.
Fraction of the cost of a new carb. All the gain.

You need significant engine horsepower increases to see a gain in boat speed , on the water.
The tunnel ram works very well on boats and will make the most power on your motor.
But do not make the mistake of choking it with tiny carbs. Use two 650's or two 750's
on it. Two 750 edelbrocks would be cool.

A cross ram would fit under the hood!

That old wives tale comes from people who can't build and tune carbs.

thats just silly.. if that had any truth to it, all the carb based engines at engine masters would have the biggest honk'n dominator on top..
they don't

Thats not silly its true you might not gain any horsepower from the bigger carb unless you needed more carb in the first place but tuned and built right you will not lose any either one reasons why they dont all have bigger carbs is cost have you prices one them big honkin dominator lately and whos going pay all that money if you not gaining a lot of hp not me

sorry signal strenth goes out the window.. if you want only peak hp..
then I'd guess it might be right..
some like having a powerplant that doesn't cough and fart untill 2500rpm+
and those pro's at engine masters the cost of a dominator is peanuts..

The signal strength is more than adequate if you know what you're doing- again most people just don't know what they're doing.

As for Engine Masters- the carbs are restricted by the rules.

man you could save hollley a ton of money.. look at all the parts they'd not have to stock or make.. warehouse if they could just cast a dominator and make it work for everything..
guess holley doesn't know either.. you should go pitch your thoughts to them.. at it save them a ton of dough..

That would actually lose holley a ton of money... And that's where professional carb shops come into play, fixing holley's short comings.
