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!
