Outboard Flush Quick Connect

The Aftermarket Quick Flushing Solution for Mercury, Yamaha and Suzuki Outboard Engines

Stop wrestling with stubborn flush plugs after every trip. The Flush-M Quick Connect permanently replaces the OEM flush plug on your outboard engine, giving you a fast, tool-free way to flush saltwater, sand, and debris from your engine's cooling system in minutes, every single time.

Protect Your Outboard Engine from Saltwater Damage

Flushing your outboard motor after saltwater use is one of the most important steps in marine engine maintenance. Salt buildup inside the cooling system causes corrosion, blocks water passages, and shortens engine life. With Flush-M™ installed, there's no excuse to skip a flush — just snap on your garden hose, turn on the water, and you're done in 5–10 minutes. No tools. No hassle. No missed flushes.

Built for Mercury, Yamaha and Suzuki Outboards

The Flush-M is a precision-fit aftermarket flushing solution engineered for today's most popular outboard brands:

• Mercury outboard flush — Compatible with Verado, Pro XS, FourStroke, and SeaPro series engines, all HP ratings from 75HP to 500HP, including V10 models
• Yamaha outboard flush — Fits 4-stroke models from 25HP to 300HP
• Suzuki outboard flush — Precision-fit for DF and DT series outboards

A Must-Have for Single and Multi-Engine Boats

Whether you run one engine or two, flushing tight twin-engine setups has never been easier. The low-profile Flush-M™ quick-connect fitting sits flush against the cowling, leaving enough clearance to attach your hose even between closely mounted engines.
