Ongaro Adjustable Wiper Arm – 10–14" – Black Stainless – SED-413114B-1

The Ongaro SED-413114B-1 is an adjustable-reach wiper arm built for smaller helm panels on tenders, runabouts, and compact powerboats. With a reach range of 10 to 14 inches, it accommodates a variety of pivot-to-blade-tip distances without requiring a custom-length arm, making it a practical choice for both new installations and blade replacements on smaller vessels.

Constructed from black stainless steel, this arm holds up in saltwater environments and keeps a clean, non-reflective profile at the helm. The standard hook-type connector is compatible with the majority of marine wiper blades in the 11–14" range, including all hook-style blades in our catalog.

Key Features

• Adjustable reach from 10" to 14" — fits a range of compact 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, professional helm appearance
• 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 small powerboats, RIBs, tenders, and any single-wiper helm setup where the windshield sweep is 14" or less. It’s also commonly used as the shorter arm in an asymmetric dual-wiper system where the co-pilot side has a smaller sweep than the driver’s side. For longer windshield configurations requiring a 13–18" reach, see the companion arm below.

Parts Desk Insights

The 10–14" range covers the most common wiper arm length for small powerboats and tenders — if you’re unsure of your exact pivot-to-tip measurement, this arm’s adjustability gives you room to dial it in on the vessel rather than guessing at the time of order. Set the arm length before attaching the blade, and check that the spring tension holds the blade firmly against the glass — arms set near their minimum reach tend to have the strongest contact pressure. The hook connector is standard across most marine blades, but confirm the pin diameter matches your chosen blade if mixing brands. Note: this arm is priced for the Ongaro premium build quality; budget alternatives are available in the Seachoice wiper kit. SKU: SED-413114B-1.
