Description

Tie Down Engineering 86490 is a 3-inch rubber V-bow stop for a 1/2-inch shaft. Current listings identify it as a trailer bow-stop component designed to catch and cushion the front of the boat during loading, launching, and trailering.

This is the brown rubber style commonly used on smaller trailer bow-stop setups where the roller needs to center the bow and provide a soft contact point at the winch stand. Tie Down lists the part as a 3 in. Rubber V-Bow Stop 1/2 in. Shaft.

Compatibility / Application
Commonly used on boat trailers that accept a 3-inch V-bow stop with a 1/2-inch shaft. Fitment is determined by the trailer’s bow-stop bracket, shaft diameter, and the existing roller size already on the trailer rather than by boat engine model.

Fitment Notice
Please confirm the trailer uses a 3-inch V-bow stop and 1/2-inch shaft before ordering. Matching the shaft diameter and bow-stop width is the key fitment check on this part.

When This Part Needs Replacement
Replace this bow stop when:

• the rubber has hardened, cracked, or split
• the V-shape is deformed or flattened
• the bow no longer centers cleanly against the stop
• the old stop has worn enough to reduce cushioning or alignment

Installation Notes

• Confirm the shaft size is 1/2 inch.
• Match the replacement width to the existing bow-stop setup.
• Inspect the shaft, brackets, and end hardware during replacement.
• A fresh V-bow stop helps protect the bow and improves centering during loading.

Parts Desk Insight
On trailer bow stops, the two details that matter most are the shape and the shaft size. A V-bow stop is meant to catch and center the bow differently than a straight roller, so swapping between the two only works when the trailer setup and hull shape call for it. For this one, the important checks are simple: 3-inch V style and 1/2-inch shaft.
