Flushmaster Automated Outboard Flushing Systems at CritPro
Flushmaster is a brand of portable, automated outboard engine flushing systems developed by Seamule, LLC. It was designed to take the hassle out of one of the most important chores in saltwater boating, which is rinsing salt, sand, and debris out of the cooling passages after every trip. The system arrived on the market in the early 2020s and quickly gave boaters a simpler alternative to standing at the dock with a hose and a set of flush muffs. CritPro carries a growing selection of genuine Flushmaster systems, hose kits, and accessories for outboard owners.
Flushmaster is especially well known for its battery-powered controller, which connects to your engine's flush ports through quick-connect fittings and flushes each outboard in sequence with fresh water. You press one button, and the unit runs a timed flush on each motor, then shuts off and blocks water flow, so there is no need to stand by the boat. The lineup includes 2-outlet systems for single and dual engines and 4-outlet systems for up to quad engines, offered with hose kits in several lengths. Engine-specific flush port quick connects are available for Yamaha, Mercury, Honda, and Suzuki outboards, along with accessories such as a storage bag, cradle, and suncover.
Whether you keep your boat on a trailer, a lift, or a dock, Flushmaster is portable and needs no hardwiring, so you can connect it to a water spigot or hose and set it up in minutes. Regular freshwater flushing helps prevent salt buildup and corrosion inside the engine, which protects your investment and keeps your outboards running reliably season after season. From a single-engine center console to a quad-engine offshore boat, the brand offers an easy, repeatable way to keep every motor clean after every trip.
