How to Install Boat Trailer Fenders
- 1). Park the trailer on a flat, paved surface. Detach it from the tow vehicle and place wheel chocks behind each trailer wheel.
- 2). Align the right side trailer fender -- check if the fenders have proprietary right and left designations -- with the wheel well mounting holes on the trailer. Insert the lock bolt into each hole on the fender so they go through the trailer's mounting holes.
- 3). Install the nuts onto the bolt threads under the fender and wheel well, and holding them in place with an adjustable wrench while you use a ratchet to tighten each bolt to the trailer. Install the bolts for the other fender in the same manner.
