The Smarter Way to Flush an Outboard Motor
Flush-M™ is the creator of the original, US-patented quick connect outboard flush kit, engineered to make outboard engine maintenance fast, reliable, and frustration-free.
We design engine-specific flushing solutions for Mercury®, Yamaha®, Suzuki®, and Honda® 4-stroke outboard motors, helping boat owners properly flush their engines after saltwater and freshwater use — and prevent outboard corrosion before it starts.
Our purpose is simple:make it easier for boaters to protect their engines and extend their lifespan.
Why Flush-M™ Was Created
Flushing an outboard motor is one of the most important steps in routine engine maintenance — yet it is often skipped.
Many boat owners struggle with:
- Hard-to-remove OEM flush plugs
- Awkward or unreliable hose connections
- Inconsistent water flow during flushing
When flushing is inconvenient, it doesn’t get done consistently. Over time, this leads to salt buildup, internal corrosion, restricted cooling passages, and premature engine wear.
Flush-M™ was developed to eliminate these pain points by turning flushing into a simple, repeatable habit.
What Makes Flush-M™ Different
Flush-M™ is not a generic garden fitting or aftermarket adapter. It is a marine-engineered outboard flush kit, designed specifically for modern outboard engines and harsh marine environments.
Each Flush-M™ Quick connect:
- Enhances the factory sealed flush plug
- Provides a secure, watertight hose connection
- Delivers consistent freshwater flow
- Is UV-protected and corrosion-resistant
- Requires no special tools to connect or disconnect
With Flush-M™, flushing your outboard motor takes seconds to set up and minutes to complete.
