I am working on an older polarkraft 14' flat bottom. The question I have is where should the cav. plate be? Even with the bottom of the boat or above due to the tunnel? When I purchased the boat it had a redneck engineered lift for the motor(40hp nissan)that puts the cav plate about 2-3 inches above bottom of boat. the only reason asking I cannot seem to get the motor to get to full power. It does super on muffs but when getting on the water it seems to bog out about 3/4 throttle. Wondering if cavitation is causing this. Thanks for any input.. Mike from Gtown
