Sea-Dog Adjustable Wiper Arm, 13–18 in. – Hook Style, Black
A straightforward, dependable wiper arm for mid-size boat windshields. The Sea-Dog 354-413168B1 is constructed from powder-coated 304 stainless steel and adjusts from 13 to 18 inches, giving you the flexibility to dial in the right sweep length for your windshield. The J-hook (automotive-style) blade attachment makes blade replacement quick and easy — no special tools, no proprietary clips.
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. A clean, practical choice for single-motor wiper setups where a standard sweep pattern is all that’s needed.

Parts Desk Insights
Best suited for mid-size boat windshields in the 13–18 in. sweep range where a clean, no-frills single-pivot arm is the right choice. This is the standard version of the Sea-Dog J-hook arm in this size — if you need the ability to adjust the blade angle or control the park position, step up to the Sea-Dog Adjustable Wiper Arm with Pivoting Tip, 13–18 in., which adds an adjustable tip for that purpose.
