Sierra 18-6811 Power Trim Motor, Replaces Yamaha 62Y-43880-00-00, Fits 115-225HP Outboards 1997-2002

The Sierra 18-6811 Power Trim Motor is a replacement power trim motor built for Yamaha outboards rated 115-225HP (1997-2002). It handles the job of raising and lowering the outboard's trim and tilt angle, driving the hydraulic pump that powers the trim/tilt system. When a trim motor wears out or fails electrically, the outboard can lose the ability to trim in or out, so replacing it with a correctly specified unit like the 18-6811 restores normal trim and tilt operation.

This trim motor connects using a 2-wire ring terminal connection and mounts with a 4-bolt pattern, matching the factory setup on covered Yamaha outboards so it installs in place of the original motor without modification. An O-ring is included with the unit, which seals the motor housing against water intrusion at the mounting point, an important detail for a component that lives in the outboard's lower housing area exposed to moisture and spray.

The Sierra 18-6811 is cross-referenced to the original Yamaha trim motor part numbers it replaces, so buyers can confirm fitment against their outboard's existing part number before ordering. It is intended as a like-for-like replacement for the factory trim motor on qualifying 115-225HP Yamaha outboards from the 1997-2002 range.
