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.

Product Details

The SeaMule SM-FM4007 Flushmaster is a revolutionary marine-grade automated outboard flushing system designed to simplify engine maintenance for quad outboard motor setups. This portable, weatherproof device eliminates the hassle of manual flushing by automatically cycling through up to four engines sequentially, ensuring thorough cleaning and optimal engine performance with just the push of a button.

Key Features:

  • Four-outlet system with four 7-foot marine-grade EPDM hoses included for quad outboard applications
  • Battery-powered operation using three AA batteries (included) for portable use anywhere
  • IP67 waterproof certification - fully submersible and built to withstand harsh saltwater environments
  • Sequential automated flushing - flushes each motor individually for 15 minutes (factory default, fully programmable)
  • Auto shut-off with audible completion alert - automatically blocks water flow when cycle is complete
  • Durable construction with waterproof ABS housing, 316 marine-grade stainless steel internals, and sealed rubber gaskets
  • Compatible with four-stroke outboards and standard flush ports
  • Can be mounted permanently to dock pilings or used portably in storage bag
  • Programmable flush duration per outlet using intuitive +/- buttons

What's Included:

  • Flushmaster 4-outlet control unit
  • Four 7-foot marine-grade EPDM outlet hoses with fittings
  • Three AA batteries
  • Screwdriver for programming adjustments
  • Complete instructions

How It Works:

Simply connect the Flushmaster inlet to your freshwater source (garden hose, spigot, or plumbed water line), attach the four outlet hoses to your outboards' flush ports, press ON and START, then walk away. The device automatically sends water through each outlet sequentially for your programmed duration, then shuts off and blocks water flow when complete. No need to monitor, disconnect hoses, or turn off the water supply until your next outing.

Protect Your Investment:

Proper flushing after every saltwater use is critical for maintaining your outboard warranty and preventing costly repairs from salt buildup and corrosion. According to manufacturer recommendations, engines should be flushed immediately after use while still hot for 15 minutes each. The Flushmaster makes it effortless to maintain this essential routine, saving significant time compared to manual flushing methods.

Backed by a 1-year manufacturer warranty and 30-day performance guarantee. Note: Flush Port Quick Connects for Mercury, Yamaha, Suzuki, and Honda outboards are sold separately and provide even faster hookup convenience.
