Sea-Dog Standard 12V Wiper Motor, 2-1/2 in. Shaft – Black | SKU 354-412321B3
A versatile 12V wiper motor designed for interior or protected mounting locations. The Sea-Dog 354-412321B3 features a highly adjustable sweep angle — factory preset at 80° or 110°, but field-adjustable to seven positions from 40° to 110° — giving you precise control over the wipe pattern to match your windshield geometry. The 2-1/2 in. shaft is a common size for standard marine wiper arm mounting.
The housing is constructed from powder-coated aluminum with a stainless steel base plate, shaft, and knurled drive nut for corrosion resistance. Adjustable right or left-hand park (factory preset for left-hand park) means the blade can be set to rest at either side of the windshield. Powers up to a 14 in. arm and blade combination (21 in. total length) using standard wiper arms. CE approved and backed by a 3-year warranty.

Parts Desk Insights
Best suited for interior or protected mounting locations where the motor is shielded from direct spray and weather — not designed for exposed deck or exterior mounting. The seven-position sweep angle adjustment is a standout feature, making this motor adaptable to a wide range of windshield geometries without needing to source a different motor. The same-footprint compatibility with competitive standard motors makes it a practical direct replacement for existing installations.
