Post by: jet boat performance on July 15, 2009, 09:21:48 PM

These folks drove 1000 miles from NM last nite to hang out on the Central Coast while we swapped some HP into this Beautifull open bow cruiser , seems this boat was produced with a late model SBC factory roller motor , Installing about 450 HP BBC, mor pics top come Tom

RE "set back" Yes John however its  a "marginal job" IMO  don't care for the rigging stlye ,poor fit , attack angles wrong (jets set incorrectly) We'll have Josh work some magic on the setup once the Big motor is ready next week More pics to follow ..

Tom, does that setup pull from a second inlet at the bottom of the boat to feed water to the motor, or is it jet pump fed?

im guessing, by the water pump, it has a second inlet..

Nathan on the sbc the "raw water " is supplied by the jet , the excess is "bypassed" and thethe waterpump which is designed for fresh and salt water use is a circulating pump Tom
