A boat trailer hitch extension will help you launch and retrieve your boat from the water while keeping your vehicle on dry land. Follow these steps to attach and use a hitch extension on your boat trailer.

 

 

Step 1: Measure the Extension Length You Need

Measure the trailer hitch extension length you need. Purchase an extension 2 feet longer than this length to allow for the mounting bracket. If you use a driveable motor home or cabover truck to tow your boat, buy the 12-foot hitch extension.

 

Step 2: Install the Extension

Assemble the hitch extension according to directions, and jack it up under your trailer hitch. Align the extension assembly under your trailer hitch and trailer, and mark the drill holes. Drill 1/2-inch holes in the trailer hitch shaft and attach the hitch extension with the long bolts and lock nuts included.

 

Step 3: Use the Extension

When you reach the launch point, switch over to the extension hitch coupler. The trailer hitch extension moves out to its full length. Put the locking pin in place. After launch, remove the locking pin. The extension will slide under the boat trailer again.
