C.E. Smith Bow Y-Stops: 29551 vs 29552 Size & Fit Guide

The Y-shaped rubber stop on a boat trailer helps cushion the bow where it meets the winch stand during loading. C.E. Smith offers two black natural-rubber replacements in these listings: a larger 29551 and a more compact 29552. They differ in the mounting block, overall span and bolt opening, so measure the original rather than ordering by appearance alone.

Which size fits your winch stand?

29551 — 3 × 3-inch mounting sectionA 6⅝-inch-wide Y shape, with a nominal ½-inch mounting-bolt opening. Choose it when those measurements match the original bracket and stop.
29552 — 2 × 2-inch mounting sectionA 4-inch arm span with a nominal ⅜-inch mounting-bolt opening. This is the smaller stop for the matching winch-stand arrangement.

C.E. Smith bow Y-stop specifications

MPN Mounting section Arm span Shaft opening Material

29552 2 × 2 in 4 in ⅜ in Black natural rubber
Measure three things: the stop's square mounting section, the full span across its Y-shaped arms, and the hole for the mounting bolt. The 3 × 3-inch and 2 × 2-inch sizes describe the mounting section—not the overall arm-to-arm width. Changing the stop size or bolt diameter can change its position on the winch post.

Check the original stop before buying

  1. Measure the mounting block. Compare its depth and width with the space between the winch-stand flanges. A stop that is too wide or too narrow may not sit correctly.
  2. Measure across the arms. The 29551 has a 6⅝-inch span, whereas 29552 measures 4 inches. Check the bow shape and position where the boat meets the stop.
  3. Confirm the bolt opening. The nominal openings differ: ½ inch for 29551 and ⅜ inch for 29552. Match the actual shaft and bracket holes.
  4. Inspect the bracket and rubber. Cracks, compression damage, shifted winch-post hardware or corrosion can affect the replacement installation.
  5. Check what is supplied. Each listed product is one rubber Y-stop. Confirm the required bolt and retaining hardware separately rather than assuming they are included.
