300/440/550 440/550 to 650 conversion...top speed

[koxx.dta]

what would be the best setup (440 or 550 pump) to use on 650 conversion to get most top speed? only weigh 120 so take off is not a problem looking to get 50mph out of 650 or 750 if i have to in a 440/550 hull...i know ? has been asked to death but most people looking for take off i want top end

You are going to want to run a 440 pump with a really tall pitch prop somewhere in the 18-20 pitch range. Should run upper 40's to 50mph range.

Get a couch. They can go up to 80 mph (speed limit set by USCG).

Pay careful attention to which ride plate and intake you use as both can reduce top speed.
