What adjustable length ranges are available?

This wiper arm comes in two adjustable ranges: 10 to 14 inches, and 14 to 20 inches, so you can match the arm to the reach your windshield requires.

How do I pick the right length for my boat?

Measure from the wiper motor shaft to the far edge of the area the blade needs to clear. If that distance falls between 10 and 14 inches choose the shorter arm; if it falls between 14 and 20 inches choose the longer one.

What material is this wiper arm made from?

It is made from stainless steel, chosen for corrosion resistance in a marine environment.

Does this wiper arm come with a wiper blade?

No. This is the wiper arm only; a wiper blade is a separate part.

Is it sold as a single arm or a pair?

Each SKU is sold as a single arm, not a pair. Order two if your boat uses dual wipers.

What thread size does this arm use for mounting?

The arm has a 3/4 inch NPT thread with an elbow connector for attaching to the wiper motor shaft.

What connector type does this arm have?

It uses an elbow connector for mounting to the wiper motor.

Will this arm fit my existing wiper motor?

It is designed to fit standard 3/4 inch NPT wiper motor shafts common on Marinco and compatible marine wiper systems; confirm your motor's shaft and thread size before ordering.

The Marinco Deluxe Stainless Steel Wiper Arm is a marine-grade replacement arm built to keep your windshield wiper system running reliably in wet, salt-laden conditions. Machined from stainless steel and finished for corrosion resistance, this arm connects your wiper motor shaft to the blade with a secure elbow connector and 3/4 inch NPT thread, and telescopes to fit a range of windshield heights so you get a precise fit without cutting or modifying the arm. Sold as a single arm (no blade included), it is the direct-fit upgrade for boaters replacing a worn, corroded, or broken factory arm on center-console, cruiser, and pilothouse windshields.

Sizes & Options

This wiper arm line is available in two adjustable length ranges to match the reach your windshield needs: 10 to 14 inches for shorter wiper sweeps, and 14 to 20 inches for taller windshields or longer blades. Measure the distance from the wiper motor shaft to the outer edge of the area you need cleared, then choose the arm whose adjustable range comfortably covers that measurement. Both options share the same stainless steel construction, elbow connector, and 3/4 inch NPT thread, so fit and finish are identical aside from length.
