    275 Volvo Weak Trim / Lift-gctid816494

    1986 Contessa 2850 w/Volvo 270 - 290? outdrives. Owners Manual suggests 225E / 275. Motors labeled 225E, no id on outdrives. Port outdrive lowers and only raises with manual assist. Starboard side works fine. Can hear port electric trim motor operating when holding drive up manually. Could this be a weak battery or electric motor. Any suggestions on where to start?

    Thanks.

      If it's the worm gear style there is a good chance the shaft is bent or gaulled causing excess friction. Or if the seals have failed tgere could be corrosion in the shaft bore. It's a shitty system to disassemble, it usually grows together.

        Mark, the AQ225E w/ the 275 drive did not have power trim. These drives were equipped with an electrical/mechanical Lift Out device only.

        With the Lift Out device...... an electric motor operates a worm-drive reduction gear system.

        This "driven" gear (via a clutching system) in turn operates a cast iron double Allen thread component (female threads).

        This part raises and lowers a shaft (refered to as a "vice rod") with male double Allen threads...... (similar to an old car/truck "screw jack")

        As the vice rod is threaded downward, it depresses an arm that is integral with the main suspension fork. This is what lifts the stern drive out of the water. As it's direction is reversed, it retracts and lowers the stern drive down.

        If the control unit's (the black box) relays and micro switch have been circumvented while operating the electric motor, the vice rod's micro switch will not interrupt the Negative current. This typically results in a sheared or broken cast iron clutch componpent.

        Things to look for;

        ..... a broken cast iron clutch component

        ..... a bent vice rod

        ..... a weak electric motor

        If you are going to remove the Lift Out unit..... DO NOT attempt to wedge anything between the mounting flange and the transom shield!
