Seachoice Engine Flush Kits: Protect Your Outboard After Every Outing
Salt water is one of the most relentless enemies of a marine engine. Every time you pull your boat from the water, microscopic salt crystals, sand particles, and silt are left behind inside the cooling passages of your outboard or inboard/outboard motor — quietly accelerating corrosion and clogging the very channels designed to keep your engine cool. Engine flush kits are the first line of defense, and few brands have made them as accessible and reliable as Seachoice.
Established in 1988, Seachoice has grown from a focused marine hardware supplier into a brand that offers thousands of parts and accessories trusted by recreational boaters, anglers, and watersports enthusiasts worldwide. Run for and by boaters, the company has built its reputation on delivering quality marine solutions without the premium price tag — and their engine flush line is a perfect illustration of that philosophy in action.
What Seachoice Engine Flushes Do
Seachoice's engine flush products are engineered to connect directly to your outboard motor's flushing port, allowing a garden hose to circulate fresh water through the engine's internal cooling system. This process efficiently flushes away salt, silt, sand, and alkali deposits that accumulate after time on the water. The result: reduced risk of clogging and corrosion, and a meaningfully extended engine life.
Seachoice offers motor flush kits in multiple configurations to serve a wide range of popular engine brands. Their Outboard Flush Kit (e.g., part #50-18411) is designed specifically for Mercury, Mariner, Yamaha, Honda, and Suzuki outboards, featuring a quick-connect design that easily snaps onto the flushing port with no tools required. A companion kit (part #50-18401) is tailored for OMC and Evinrude outboards, ensuring boaters across engine platforms have a purpose-fit option. For broader compatibility, Seachoice's Universal Motor Flusher (ProFlo, part #18301) is designed for use with most outboards and inboard/outboards equipped with side water inlets, flushing away sand, silt, and salt to prevent clogging and corrosion.
