<h3>About SeaMule</h3><p>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.</p><h3>The Flushmaster: Redefining Outboard Engine Maintenance</h3><p>At the heart of SeaMule's lineup is the <strong>Flushmaster</strong>, 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.</p><p>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 <a href="/18624-seamule-engine-flushes-200369">Engine Flushes</a> 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.</p><p>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.</p><h3>Motor Flushers & Flushing Accessories</h3><p>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.</p><h3>Engine Parts & Accessories</h3><p>SeaMule rounds out its product range with a selection of Engine Parts &amp; 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.</p><h3>Why Boaters Trust SeaMule</h3><ul style="list-style:disc"><li><strong>Automated convenience:</strong> Set it and walk away — the Flushmaster handles the entire flush cycle without supervision.</li><li><strong>Marine-grade construction:</strong> Every product is designed to withstand saltwater, UV exposure, and the rigors of regular marine use.</li><li><strong>Broad compatibility:</strong> Flushing solutions for Mercury, Suzuki, and other major outboard brands.</li><li><strong>Complete systems:</strong> SeaMule offers everything from the core flushing device to mounting cradles, quick-connect ports, and extended hose kits.</li></ul><p>For any boater serious about protecting their outboard investment, SeaMule offers a thoughtfully engineered suite of products that make proper maintenance the easiest part of the day.</p>

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.
