Description
Rectangle Boat Motor Muffs make routine engine flushing straightforward at home, at the dock, or before storage. Place the muffs over the intake, connect a standard garden hose, and run water through the engine for flushing, warming, idling, or winterizing prep.
The rectangle ears are shaped for wider, flatter intake openings and flex to help create a water tight grip. The rotating U channel gives the muffs the adjustability needed for most outboard and I/O engine setups.

A hose sprayed near the intake can miss the seal and starve the water pump, risking a burned out impeller. Motor muffs clamp snugly over both intake ports so the engine draws water the same way it would in the water.

Frequently Asked Questions
Yes, these feature a universal design with rotating ears and a 9 1/4" deep frame to adapt to the majority of outboard and I/O engines on the market.
Absolutely. These muffs are a critical part of a winterizing kit, allowing you to run the engine on land to circulate fresh water or antifreeze.
No tools are required. The flusher connects directly to a standard garden hose, and we even include a quick-connect adapter for your convenience.
The 3 1/4" x 5" rectangular shape provides a larger surface area and a better "pinch" on the intake vents of modern, larger lower units, ensuring a tighter seal.
It is recommended to only idle your engine while using a flusher to ensure the water pressure from the hose is sufficient to keep the engine cool.
