I usually hang out on the Johnson forums but I have a friend with a Godfry 24' pontoon that has a 96 115HP inboard v4, at WOT his tach only goes up to about 4500 RPM, does anyone know if that is the recommended RPM at WOT on this engine? I know on my Johnson Outboard you size the prop so the motor runs at about 55RPM at WOT.
