MPH out of a 22'?

[trc2]

when I had my 1997 22 scarab it had a 310 7.4 454 efi in it and it ran on gps 68 to 70 then I had a 454 mag 385 put in it and it ran 73 gps hope this helps this was with a 25 pitch 3 blade prop

[jbraun2828]

will run close to 70 with a mag, water has to be pretty flat

I have a 1990 21 excel stock 7.4 3 blade quicksilver 61-62mph. boat weighs 3800lbs. i believe a 22' is 3200lbs. If that helps.

My 22 stock went 62 mph on a hand held GPS
Then I did:
H/C/I 454 with a 175 shot of Nitrous ran in the mid 80's with a labbed 30 bravo1

Hi,
I exactly need the kind of tweeks you above suggested? what is the easiest way to tweak it to 500 hp?

The HP 500 fastscarab22 is referring to is a Merc 502ci 500 Horsepower engine. The tweaks you need to make your stock 330 500 horsepower is about $4000-$5000.

Do a search in the Performance Technical section. "330 on Roids"

I heard 65 -70 mph is running well with a stock unit ...I have a stock 350 and can get 63 with with two people and a full tank ....

Do you know the capicity of the fuel tank ??
