Can't trim at speed (20-25 Knots) have to drop speed to trim and then power up again. Powered by a Volvo AQ151A power unit on an American Falcon 18.5 ft boat. Can anyone help??????????????
Is the trim pump motor running when you are at speed? Could be dirty/loose connections causing low amperage to the motor. Could also be a bad motor. Does it sound normal when engine is not running?
