I have a 1998 Mariner 135 Optimax, that runs great. My power trim was working both up and down, just the other day. Now my unit (& I'm talking outboard here) is now stuck in the up position. I believe I have an electrical problem, since the trim motor will raise the unit, but I not lower it. I can't hear anything either. <br /><br />How stupid is it to manually lower the unit? Will it drop like 500# motor, or will the pressure be released gradually letting the motor down?<br /><br />My thinking is that if I could lower in some, I might be able to get the trim motor to work going down as well.<br /><br />Any comments & remarks are encouraged. Thanks, Bum
