Trim down very slow Mercruiser MC-1 sterndrive. The up is normal, and trailer is normal. I can go directly from the battery to the green line on the pump and it will go down real fast using a 6 guage wire. I can't figure out why it's so slow using the trim down on the throttle. It has a new solenoid, and new breaker. Any ideas would be appreciated.
