Default Question on what speed to expect from 375 hp 496 mag in 262 Montereycruiser

LakePowell wrote:
I'm thinking of buying a 2001 Monterey 262 cruiser. It has the 375 hp
496 mag in it. Dry weight is listed at 5,500 lbs. Specs say it should
go about 50 mph top speed, but I'm assuming that's under ideal
circumstances and at sea level. Test drove the boat at 4500 feet of
elevation and top speed was 38 and it held 30 mph at 3700 rpm. Does
that sound about right or might something be wrong? Would greatly
appreciate if anyone with relevant experience could help.

Thanks!


The rev limiter cuts in at ~4800 on that motor. It appears that you are
way over pitch on the props as set up now... 4600 would be a good WOT
max, and at about 44-45 mph for 4000 feet. Other factors to consider
too before jumping to a new prop set - did you use the trim for optimum
performance, does the boat have trim tabs, and were they used properly?
