Harborwright sells the part only — we don't install it. These are general steps; your boat and the maker's manual come first. If you're not sure, have a marine shop fit it.
Safety: Tighten every U-bolt nut and recheck them after the first few launches.
Steps
- Load the boat once and note where the hull sits. The guide-ons go at the back of the trailer, one each side.
- Fit the brackets to the frame with the U-bolts, on top of or below the frame, and snug the nuts.
- Fit the PVC posts and set the width so the posts sit just off the hull sides when the boat is centered.
- Tighten all nuts and check the posts clear the fenders and lights.
- Recheck the position after your next launch and retrieve.
