85' yamaha f9.9sk..can i change the jet pilot of a 9.9 to the jet that fits the 15sk to upgrade motor to a 15sk.? or do i have to change the whole carb....? is this possible...?
alot of parts are the same for these motors.....but, i dont want to damage the 9.9 i have....very nice and lightly used for its age....thanks for any answers given from an experienced person..heard about doing it to some motors..??????? thanks again
