Sea-Dog 413118S1 Adjustable Wiper Arm – Stainless Steel
A mid-size adjustable wiper arm built for long-term reliability in the marine environment. The Sea-Dog 413118S1 is formed from 304 stainless steel with a natural stainless finish, giving it a clean, polished look that holds up against salt air, UV exposure, and constant moisture without the risk of a powder-coat finish chipping or fading over time.
Lighter than the larger 413120 arm in the same family, the 413118S1 is a practical choice for mid-size windshield applications where a full-size arm would be more than needed. Compatible with most standard MRV and heavy-duty waterproof wiper motors with a 5/8 in. shaft diameter, as well as 1.5 in. and 2.5 in. shaft motors.

Parts Desk Insights
Best suited for mid-size boat windshields where a natural stainless finish is preferred and the larger 413120 arm would be more than needed. The stainless finish is a particularly good choice on vessels with polished stainless hardware throughout, where a black arm would stand out. For a larger arm in the same stainless family, step up to the Sea-Dog 413120S1 Adjustable Wiper Arm – Stainless Steel or the Sea-Dog 413120B1 Adjustable Wiper Arm – Black Finish. For a J-hook style arm with a specified sweep range, see the Sea-Dog Adjustable Wiper Arm, 13–18 in. – Hook Style.
