Sierra 18-6759 Tilt/Trim Motor, Replaces 394176/391264/393988/985237, Johnson/Evinrude 3-4-6-8 Cyl 1982 to Present

The Sierra 18-6759 Tilt/Trim Motor is a direct-fit replacement trim motor built for Johnson/Evinrude (OMC/BRP) outboard ignition/electrical systems. It uses the newer 2-wire design found on most 3, 4, 6, and 8 cylinder outboard applications from 1982 to present, and mounts with a 3-bolt pattern. This is the motor only, and it includes the O-ring needed for installation, so there is no separate O-ring to source before the job.

Use it to restore power tilt/trim function on an outboard whose original motor has failed or is drawing excessive current, stalling, or no longer responding. Because it is a like-for-like replacement for several OEM Johnson/Evinrude part numbers, it drops into the existing trim/tilt assembly without modification. Sierra parts are built to meet or exceed the specifications of the original equipment they replace, and this motor is backed by Sierra's standard customer satisfaction warranty.
