SeaMule SM-FMQCYCD Flushmaster Flush Port Quick Connect for Yamaha Outboards Display Package

The SeaMule Flushmaster SM-FMQCYCD is the display package version of the Flushmaster Flush Port Quick Connect for Yamaha outboards. This quick connect serves as a permanent replacement for the factory OEM flush port plug, transforming engine flushing from a cumbersome two-handed chore into a fast, one-handed snap connection. Constructed with marine-grade materials and a 316 stainless steel spring, it is built to hold up in harsh saltwater environments.

Key Features:

• One-handed snap connection — no more holding the hose while threading fittings
• Double O-ring design — extended-tip male quick connect provides a tight, leak-free seal every time
• 316 stainless steel spring — corrosion-resistant internals resist rust and seizing
• Secured locking cap — protects the port and prevents accidental disconnection underway or in storage
• Permanent installation — acts as a bridge; adapters remain snapped together while running, keeping the factory flush line configuration intact
• No special tools required — straightforward installation replaces the existing flush port plug
• Eliminates lost gaskets — snap-fit design removes the loose O-ring that typically goes overboard during conventional flushing

What's Included:

• (1) Male Quick Connect with double O-ring seal
• (2) Female Quick Connect adapters — black

Installation Overview: Unthread the existing Yamaha flush port plug and thread in the Flushmaster female quick connect on the engine side. Thread the male quick connect into the female side of the flush port. Attach the second female quick connect to your water supply hose. Connect and flush.

The SM-FMQCYCD is designed for Yamaha outboard engines 150–425 hp equipped with a flush port. It is not compatible with Yamaha outboards 50–115 hp, the XF450, or any 2024–2025 model year engines rated 115 hp or smaller. Compatible with both 2-stroke and 4-stroke Yamaha outboards in the supported power range.
