Flushmaster Outboard Engine Flush Port Quick Connect for Yamaha
Complete Your Purchase
Stop wrestling with your Yamaha's flush port.
The SEAMULE Flushmaster Flush Port Quick Connect replaces your Yamaha's factory flush plug with a permanent, snap-in fitting — turning a two-handed, gasket-losing chore into a one-handed, seconds-long connection. Just snap the hose on, flush, snap it off, and you're done. No more fumbling with threads, no more hunting for a dropped O-ring, no more excuses to skip a flush after a day on saltwater.
Key Features
- One-Handed Connection: The quick-connect bridge lets you snap the hose on and off with a single hand — no more holding the fitting steady while threading a hose with the other.
- Marine-Grade Durability: Built from marine-grade materials and rigorously tested for strength and long-term performance in harsh marine environments.
- Corrosion-Resistant 316 Stainless Steel Spring: The internal spring mechanism is made from 316 stainless steel, engineered to resist saltwater corrosion and hold up over years of use.
- UV Resistant: Constructed with UV-stabilized materials so the fitting won't degrade, crack, or discolor from constant sun exposure.
- Leak-Free, Double O-Ring Seal: An extended-tip, double O-ring design ensures a tight, secure seal every time you connect — no drips, no wasted water pressure.
- Secured Locking Cap: A locking cap keeps the port protected and prevents accidental disconnection while underway or in storage.
Benefits
- No More Lost Gaskets: Permanently replacing the OEM plug means you'll never fumble with loose gaskets or threaded fittings again.
- Faster Flushing, Every Time: Twist off the cap, snap on the hose, flush, disconnect, and twist the cap back on — a simple routine that takes the friction out of regular maintenance.
- Built to Last: Marine-grade construction and a stainless steel spring mean this fitting is designed to outlast the flushing habits of a typical boating season after season.
Installation
Unthread the factory flush port from your Yamaha outboard. Thread the SEAMULE female quick connect onto the male side where the OEM plug was removed. Thread the SEAMULE male quick-connect piece into the female side of the Yamaha flush port. Attach the second SEAMULE female quick connect to the end of your garden hose or water supply line. Once installed, simply snap the hose fitting into place each time you flush.
