12V Tilt Trim Motor for Mercury, Volvo 1975-1984

This one is 12V. Voltage has to match your machine exactly. A 12V unit on a 24V system will be damaged, and a 24V unit on a 12V system will crank slowly or not at all. If you are unsure, check the battery setup: two 12V batteries wired in series usually means a 24V system.

This unit turns bi-directional. Rotation is read looking at the drive end, the end the pulley or gear sits on. Most alternators driven by a serpentine belt turn clockwise, but always match what came off.

We list 2 vehicle and equipment applications for this tilt and trim motor. Use the "Does it fit?" checker further up this page to pick your make, model and year, or open the full applications list.

The surest check is the number stamped on the unit you are replacing. Match it against the cross reference numbers on this page. Fitment lists are a guide, and the same machine can leave the factory with more than one setup, so the number on your old part beats a model year every time.

Probably yes. One unit is sold under many numbers by the vehicle maker, the original manufacturer and the aftermarket. The cross reference list on this page shows the numbers we know map to this tilt and trim motor. If yours appears there, this is the right part.

If your number is not listed, try our cross reference lookup. It searches every number we hold, not just the ones shown here.

10814 is the Lester number. Lester is the long standing industry catalogue for rotating electrical, and its numbers are how the trade identifies a unit regardless of who sold it. We use it as our part number because it is the one identifier that stays stable across every brand that has ever boxed this tilt and trim motor.

Not necessarily. Up and down usually run through two separate relays, so one direction failing often means one relay, not the motor. Check the relays and the connections first, and check the fluid level in the reservoir while you are there. Low fluid gives you a motor that runs and a ram that does not move.

If the motor is silent in one direction and you have confirmed the relay and the ground, the motor or its brushes are the next suspects.

This is the motor. Tilt and trim assemblies are sold as motors, pumps and complete units, and the parts are not interchangeable between those forms. Match the number on what you are replacing against the cross reference list on this page before ordering.

Tilt and trim motors are built for the marine environment, but no motor survives standing water in the well or a corroded harness. When you fit a new one, clean the connections back to bright metal and protect them, since the usual cause of a second failure is the wiring that killed the first one.

New. Every tilt and trim motor we list is a new unit, not a rebuilt core, and it carries a one year warranty. There is no core to return and no deposit to chase.

Orders leave within three business days. Ships from USA. You can read the full terms in our shipping policy, and returns are covered in the return and refund policy.

Returns are accepted within the window set out in our return and refund policy,and a restocking fee applies unless the part is defective or we made the error. A unit that has been installed or used cannot be returned, so it is worth confirming fitment by part number before you fit it.
