<h3>About SeaMule</h3><p>Based in Madeira Beach, Florida — the heart of Florida's Gulf Coast boating community — SeaMule is a marine solutions brand built around one guiding philosophy: life on the water should be effortless. From weekend anglers to seasoned offshore captains, SeaMule designs products that eliminate the tedious side of boat ownership so you can spend more time doing what you love.</p><h3>The Flushmaster: Redefining Outboard Engine Care</h3><p>SeaMule's flagship innovation is the <a href="/18624-seamule-engine-flushes-201925">Flushmaster Outboard Engine Flush System</a> — widely recognized as the world's first portable, automated outboard flushing device for single and multi-engine boats. Flushing outboard motors after saltwater use is one of the most critical maintenance habits a boat owner can develop, yet it has traditionally been a time-consuming, hands-on chore. The Flushmaster changes that equation entirely.</p><p>The device handles up to four outboard motors sequentially, flushing each one for a pre-programmed duration before automatically shutting off and blocking the water flow — no babysitting required. Powered by just three AA batteries, it connects easily to any standard freshwater source and cycles through every motor in order, ensuring thorough cleaning without the owner having to stay present.</p><ul><li><strong>IP67 waterproof certified</strong> — built to withstand harsh marine environments, including rain, spray, and accidental submersion</li><li><strong>Compatible with four-stroke outboards</strong> across major brands including Mercury, Yamaha, Suzuki, and Honda</li><li><strong>Available in 2-outlet and 4-outlet configurations</strong> with multiple hose length options to fit a wide range of boat setups</li><li><strong>Auto shut-off</strong> once all motors are flushed, conserving water and freeing up your time</li><li><strong>Included 1-year warranty</strong> for peace of mind</li></ul><h3>The Complete Flush System</h3><p>SeaMule doesn't stop at the Flushmaster controller. The brand also offers Flush Port Quick Connects — purpose-built connectors that permanently replace OEM flush ports on Mercury, Yamaha, Suzuki, and Honda engines. Together, the Flushmaster and Quick Connects form a comprehensive <a href="/18624-seamule-engine-flushes-200369">outboard engine flush solution</a> that makes connecting hoses a one-handed, tool-free process. Additional Flush Hose Kits, a Housing Cradle, Portable Storage Bag, and a PVC Piling Plumbing Kit round out the ecosystem for boaters who want a fully integrated setup.</p><h3>Built for the Water, Designed for Convenience</h3><p>Every SeaMule product is engineered to hold up in the demanding marine environment — UV-resistant, weatherproof, and constructed from materials chosen for long-term durability on the water. The brand's commitment to sustainable, eco-conscious materials reflects an understanding that the boating community depends on healthy waterways. Whether you're docked at a marina, tied up at a piling, or back in the driveway after a long day offshore, SeaMule's solutions are designed to fit naturally into your post-trip routine.</p>

Product Details

The SeaMule SM-FM2009 FlushMaster is a portable, marine-grade outboard flushing system designed to automate the maintenance process for up to four outboard motors simultaneously. This dual-outlet model comes complete with two 9-foot hose kits, making it ideal for boats with twin outboard configurations.

Key Features:

  • Automated flushing system eliminates manual monitoring during maintenance
  • 2-outlet configuration with two 9-foot hose kits included
  • Battery-powered operation using (3) AA batteries for portability
  • Marine-grade construction designed to withstand harsh saltwater environments
  • Expandable to service up to four outboard motors
  • Hands-free operation saves time and ensures thorough flushing

Regular flushing of outboard motors is essential for removing salt, sand, and debris that can cause corrosion and damage to internal cooling systems. The FlushMaster automates this critical maintenance task, ensuring consistent water flow through your outboard's cooling system without the need for constant supervision. The included hose kits provide everything needed to connect directly to your outboard motor's flushing port or muff-style adapter.

Right part. Fast delivery. No issues at all.
