Galvanized Pontoon Boat Trailer Winch Seat Fits 3" Wide Winch Posts

The Galvanized Seal has a Base that has 4 mounting holes designed for 1/2" diameter, 3" wide U Bolts.  The Length of the U Bolts depends on your Boat Trailer's Winch Post Size.  For this reason, the mounting hardware is not included.  Most of the time the Winch Post size will be 3 x 3 or 3 x 4.  If you have a 3x3 winch post, the recommended U Bolts size is the 1/2" x 3" x 4 5/16" U Bolts.  If your Winch post is 3 x 4, the recommended size is  1/2" x 3" x 5 5/16" U Bolts.

This Galvanized Pontoon Winch Seat has the standard-sized mounting holes which fit nearly any Boat Trailer Winch on the Market.  Here is a link to our Winch Category, if you are needing to replace your Boat Trailer Winch as well.  This winch mounting hardware is not included with this Seat, but can often be re-used.  We do sell it separately in our Trailer Mounting Hardware Category though if needed.
