<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-FM2020 FlushMaster is a portable, marine-grade outboard flushing system designed to automate and simplify the critical maintenance task of flushing your outboard motors with fresh water. This dual-outlet system comes complete with two 20-foot hose kits, allowing you to flush up to four outboard motors simultaneously.

Key Features:

  • Dual outlet configuration supports flushing up to four outboard motors at once
  • Includes two 20-foot hose kits for extended reach and flexibility
  • Battery-powered operation using (3) AA batteries for portable, cordless convenience
  • Marine-grade construction built to withstand harsh saltwater environments
  • Automated flushing process saves time and ensures thorough engine maintenance
  • Portable design allows for easy storage and use anywhere

Regular flushing of outboard motors is essential for removing salt, sand, and debris that can cause corrosion and reduce engine life. The FlushMaster automates this process, ensuring consistent water flow through your engine's cooling system without the need to manually hold flushing muffs or monitor water pressure. Simply connect the hoses to your outboards, attach to a fresh water source, and let the FlushMaster do the work while you prep your boat or perform other maintenance tasks.
