Marinco 33007A Deluxe Stainless Steel 10″-14″ Wiper Arm

The Marinco 33007A uses stainless steel construction for marine environments and adjusts from 10″ to 14″. It features an articulating or bend-back ability to facilitate blade replacement and cleaning. Best for boats that require a compact yet durable arm on mid-size windshields. Best for boaters who need a reliable, corrosion-resistant arm with straightforward installation. Limitation: may require compatible blades and mounting hardware not included in every setup.
Marinco 33032A Deluxe Black Stainless Pantographic Arm

The 33032A offers a pantographic design that maintains consistent blade pressure across the windshield. It extends from 12″ to 17″, making it suitable for a wide range of boat widths. Best for boats where even wiping pressure is critical for visibility in spray and rain. Choose this if you want smooth, uniform blade contact; avoid if your windshield is outside the 12″–17″ range or if mounting hardware differs.
Marinco 33014A Deluxe Black Stainless Arm, 14″-20″ Adjustable

This 14″–20″ adjustable arm balances broad windshields with an articulating feature that locks into position for maintenance. The black epoxy-coated stainless steel resists corrosion, making it a solid option for boats that face heavy spray. Best for larger windshields; better for boats needing easier blade access during cleaning, with the caveat that longer arms may require extra clearance in some cockpit layouts.
Marinco 33012A Deluxe Black Stainless Arm, 10″-14″ Adjustable

The 33012A provides a 10″–14″ range with a bend-back articulating feature and additional set screw clamping at the motor shaft. This makes it suitable for boats with standard or heavy-duty motors that require a compact arm with secure mounting. Best for smaller or mid-size windshields; consider a longer arm if your windshield exceeds 14 inches.
Marinco 33037A Deluxe Pantographic Arm, 17″-22″

The 33037A is a pantographic arm designed for larger windshields, extending 17″ to 22″. It supports consistent blade pressure and includes an articulating bend-back function with an extra set screw clamp at the motor shaft. Best for boats with wide glass or multiple mounting options; use this if you need premium pressure control on big windshields, and watch for potential clearance constraints in tight helm areas.
