a guy i know stated that he has a 23 foot daycruizer,(197?) with a custom built jet, with a big block olds, thru-transom, that flies by a 55mph skiboat. oh and this olds can twist the pump to 8500 rpms and can hold 6500 for miles no-sweat. does these statementd hold water? he also brags about not slowing for the no-wake zones on the sac river.
