Sea-Dog Adjustable Wiper Arm with Pivoting Tip, 13–18 in. – Hook Style, Black
A versatile wiper arm with a standout feature: an adjustable pivoting tip that lets you set the blade at different angles to maximize windshield coverage and ensure the blade parks parallel to the window frame. This is a practical advantage on boats where the wiper motor shaft angle doesn’t align perfectly with the windshield, or where the blade tends to park at an awkward angle that looks unfinished or blocks the view.
Constructed from powder-coated 304 stainless steel, the arm adjusts from 13 to 18 inches and uses a J-hook (automotive-style) blade attachment for easy blade replacement without special tools. 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 in the 13–18 in. sweep range where blade angle or park position is a concern. The adjustable pivoting tip is the key differentiator here — it solves the common problem of a blade that parks at an angle rather than sitting flat along the bottom of the windshield, which is both a visibility issue and an aesthetic one. This is a single-pivot arm, not a pantographic design, so it’s best suited for windshields where a standard sweep pattern is sufficient. For a pantographic arm in the same 13–18 in. range, see the Sea-Dog Pantographic Wiper Arm, 13–18 in. – Hook Style. For a longer sweep range, see the Sea-Dog Pantographic Wiper Arm, 19–24 in. – Hook Style.
