Flush Master

Stop babysitting the hose, let Flushmaster do the work.

Flushmaster is the world’s first portable automated flushing system designed specifically for single, dual, triple, and quad outboard engines. No more standing around for 45–60 minutes manually switching hoses between engines. Just connect your freshwater supply and flush ports, press start, and walk away. The system sequentially flushes each engine with the proper timed flow of fresh water, then shuts off automatically.

Perfect for saltwater boaters who want to protect their investment and follow manufacturer recommendations without wasting time at the dock or boat lift.
