Ongaro Adjustable Wiper Arm – 13–18" – Black Stainless – Hook Style – SED-413168B-1

The Ongaro SED-413168B-1 is an adjustable-reach wiper arm designed for mid-size to larger powerboat windshields where a fixed-length arm won’t accommodate the pivot-to-blade-tip distance. With an adjustable reach of 13 to 18 inches, it covers a wide range of windshield configurations without requiring a custom fit.

Built from black stainless steel, this arm resists corrosion in saltwater environments and delivers a clean, low-glare appearance at the helm. The standard hook-type connector is compatible with the majority of marine wiper blades, including all Ongaro, Wexco, and Roca hook-style blades in our catalog.

Key Features

• Adjustable reach from 13" to 18" — fits a wide range of windshield pivot configurations
• Black stainless steel construction for saltwater corrosion resistance
• Hook-type blade connector — compatible with most marine wiper blades
• Low-glare black finish for a clean helm aesthetic
• Single arm — order quantity to match your wiper system
• Designed for use with standard marine wiper motors

Best Use Cases

This arm is the right choice for mid-size powerboats, flybridge cruisers, and sportfishers where the wiper pivot is set further from the windshield edge and a 10–14" arm falls short. It’s also commonly used in dual-wiper setups where the driver’s side requires a longer sweep than the co-pilot side. Pair with any hook-style blade in the 13–18" length range for a complete assembly. For shorter windshield configurations, see the 10–14" arm below.

Parts Desk Insights

The 13–18" adjustable range makes this one of the most versatile arms in the lineup — it’s the go-to choice when you’re unsure of the exact pivot-to-tip distance on a refit or when replacing an arm on a vessel where the original spec is unknown. Set the arm length before installing the blade, and confirm the spring tension is sufficient to keep the blade pressed against the glass at speed — arms that are extended to their maximum reach can sometimes lose contact pressure at higher RPM. The hook connector is standard, but verify the pin diameter matches your blade before final assembly. SKU: SED-413168B-1.
