I purchased a new electric tilt and trim from ebay still in box. It works good the only problem is it wont trim once im on plane. It is the panther model 55 up to 55HP will hold up to 250 lbs. My motor is a 1992 Yamaha 40HP. I called the panther company and they could not give me a answer. I was wondering if any one had any ideas. Is it possibly that the battery is to small I have a stowaway dual purpase battery group 27.
