Yamaha Outboard Trim Tilt Motor Replacement

Dedicated to my father who taught me early on that if I set my mind to a task, I could accomplish whatever I chose.
June 25, 2016 - Rest in peace, Dad. You are very much missed.

Replacement of the trim/tilt motor on a 2002 Yamaha 90 2 stroke. This recaps a leisurely paced 2 1/2 hour remove/replace job that was completed without removing the outboard from the boat.

The aftermarket motor that I installed January, 2015 was already showing corrosion. I decided to replace it so I could treat the corrosion before it was too severe and salvage the motor as a backup.

The replacement motor was purchased from DB Electrical and came with what appears to be a good paint job. For added protection (after taping the protruding motor section below the mounting flange - don't want paint contaminating the fluid), the motor was given 3 coats of Rustoleum primer and 2 top coats of Rustoleum paint before being installed. Hopefully this will retard corrosion.

Tools required: 1/4" drive ratchet, 10mm deep socket, 4" flex extension, 3/8" drive ratchet, 14mm socket, 17mm socket, 14mm box end wrench, #2 Phillips Screwdriver. For cleaning threads on the removed bolts, a wire brush and anti-sieze compound. Lastly, twine or mono for use as a pull string as mentioned in the video.

Yamaha recommends using Yamaha Outboard Power Trim and Tilt Fluid Oil. I have been using Dexron III/Mercon ATF and have not experienced any problems doing so.
