About SeaMule
Based in Madeira Beach, Florida, SeaMule is a marine accessories brand built around a single, powerful idea: life on the water should be simple. Whether you're docking after a saltwater run, prepping for a fishing trip, or just getting back from a day at the sandbar, SeaMule designs products that eliminate the tedious parts of boating so you can focus on what matters most — enjoying the water.
The Flushmaster: Redefining Outboard Engine Maintenance
At the heart of SeaMule's lineup is the Flushmaster, a marine-grade automated outboard flushing system that has changed the way boaters think about engine care. Flushing outboard motors after saltwater use is one of the most critical — and most commonly skipped — maintenance tasks. Traditional methods are time-consuming and cumbersome, especially for twin- or quad-engine setups. The Flushmaster solves this problem elegantly.
The device connects to a standard water spigot or garden hose and automatically sequences water through each engine in turn, flushing for a preset amount of time before shutting off completely on its own. No standing by, no remembering to turn the water off, no wrestling with hoses between engines. SeaMule's Engine Flushes category covers the full range of Flushmaster units, available in 2-outlet and 4-outlet configurations with hose kits ranging from 3 to 12 feet to suit any dock or marina setup.
Built for the demands of the marine environment, the Flushmaster features a waterproof, saltwater-resistant ABS housing, 316 marine-grade stainless steel internal components, and airtight rubber gaskets — materials chosen specifically to endure the harsh conditions that boats are routinely exposed to. A 1-year warranty backs every unit, reflecting SeaMule's confidence in its engineering.
Motor Flushers & Flushing Accessories
Beyond the core Flushmaster device, SeaMule has built a comprehensive ecosystem of Motor Flushers and flushing tools. Flush Port Quick Connects for Mercury and Suzuki outboards replace factory flush ports with marine-grade fittings that pair directly with the Flushmaster for a seamless, leak-free connection. The result is a true plug-and-play flushing experience that removes the hassle of attaching and detaching hoses after every outing.
Engine Parts & Accessories
SeaMule rounds out its product range with a selection of Engine Parts & Accessories designed to complement the Flushmaster system. From the marine-grade starboard Housing Cradle for secure device storage dockside, to portable storage bags and PVC piling plumbing kits for permanent installations, every accessory in the SeaMule lineup is engineered with the same attention to durability and convenience that defines the brand.
