My Father in law being the generous guy he is has permanently lent me his 4.2 seahawk stacer(about 25 years old, in perfect nick, very low hours, prob less than 200), while getting the info on it, i noticed that the plate says max hp 35, but it's got a 40hp on it. I'm not going without insurance, too big a risk for me. Talked to Telwater(Stacer manufacturer ) and they can't/won't do anything. What are my options ???
