The Marinco Deluxe 20" stainless wiper blade is a premium-grade blade built for mid-size to larger powerboat windshields where a longer sweep is needed for full visibility coverage. Part of Marinco’s 34000 Deluxe series, it combines a polished stainless steel frame with high-quality wiper rubber for reliable, streak-free performance in rain, spray, and saltwater environments.
The standard hook-type connector fits the most common marine wiper arm fittings, making this a direct drop-in replacement for worn blades on existing systems or a premium upgrade from a painted or plastic blade.
Key Features
- 20" sweep length — suited for mid-size to larger powerboat windshield panels
- Polished stainless steel frame for corrosion resistance and a premium helm appearance
- Marinco Deluxe 34000 series construction
- Standard hook-type arm connector — fits most marine wiper arms
- Marine-grade wiper rubber for streak-free performance in all conditions
- Direct companion to the Marinco 18" Deluxe SS blade
Best Use Cases
This blade is the right choice for mid-size powerboats, express cruisers, and sportfishers where the windshield panel requires a 20" sweep for full coverage. It’s also a popular upgrade choice when replacing a shorter or lower-quality blade on an existing stainless arm. For a 20" blade in a black finish, see the Ongaro 20" Silver Stainless below — both are hook-type and interchangeable on compatible arms. For smaller windshields, the 18" Deluxe SS is the direct shorter sibling.

Parts Desk Insights
The 20" length is one of the most common sizes for single-motor wiper setups on express cruisers and mid-size sportfishers — if you’re replacing an OEM blade and the original measured 20", this is a reliable like-for-like swap. The polished stainless frame is a cosmetic step up from the black finish options and suits vessels with chrome or polished hardware at the helm. Blade rubber should be inspected annually — UV exposure degrades the rubber even when the wiper isn’t in regular use, and a hardened blade will streak or skip before it visibly cracks. Confirm your arm’s hook pin diameter before ordering if mixing brands. SKU: MAR-34020S.
