First off, thanks for letting me post this,went fishing the other day and everything was going just fine until we got ready to head home,I started the motor, which is a 1989 50 hp Force, put it in gear and it just set there and the motor would only Rev up, would not go forward.I put it in reverse and it worked just fine,I,m sure the prop or nothing else hit anything,it,s like it just happened while we was there fishing,sure hope someone out there can help.
