How to Paint an Outboard Motor

Outboard engines face adverse conditions out on the water, and if you’re rebuilding yours, a fresh coat of paint is a fantastic finishing touch. 

Painting an outboard is a simple job, but it does require a bit of patience. Watch the video above and follow the steps below to learn how to paint an outboard engine.

Supplies Needed - Painting an Outboard Engine

NOTE: We repainted a Mercury Tracker 40 outboard, so naturally we went with Mercury paints. Before you paint an outboard (or anything for that matter), make sure you keep the paint away from the areas you don’t want affected.

Repainting an Outboard Motor Steps

Step 1. Use masking tape on all the openings inside the motor, and trim the edges down precisely with a sharp hobby knife. Cover in bolt holes, moving parts and electrical connections.

Step 3. Wait 24 hours for the primer to dry thoroughly before adding the paint. 

Step 4. Apply the paint the same way as the primer, keeping the can moving while spraying a light coat. Wait at least three hours for the paint to dry, then check to see if you need a second coat.
