Outboard Motor Rectangular Ear Muff Engine Flusher

Outboard Motor Rectangular Ear Muff Engine Flusher for Fresh‑Water Cleaning

This outboard motor water flush rectangular ear muff engine flusher is designed to make routine engine rinsing simple and consistent after every trip on the water. By connecting to a standard garden hose, it delivers a steady flow of fresh water directly to the cooling intakes of your outboard, helping remove sand, salt and silt that can build up during use. Suitable for both private boat owners and marine professionals, it supports regular maintenance without the need for complex tools or workshop equipment.

The rectangular ear muffs feature large, black rubber cups that sit securely over the water intake slots on a wide range of outboard engines. The soft, pliable rubber forms a reliable seal to help ensure water is directed into the cooling system rather than leaking around the sides. A black‑coated spring steel frame provides firm tension and quick, secure connection to the lower unit, while the electroplated clamp construction is designed for repeated use in marine environments. The included quick‑connect style hose fitting allows you to attach a standard garden hose in seconds, so you can flush the engine on the trailer, at the dock or in the yard.

Made from durable materials including HSS components and resilient rubber, this engine flusher is built for regular seasonal and post‑trip flushing routines. The compact size makes it easy to store in a dock box, onboard locker or garage. To use, simply slide the rectangular cups over the engine's water intake slots, ensure they are centered and firmly seated, connect your garden hose to the quick‑connect fitting, and run fresh water while the engine is idling according to the manufacturer's guidelines. This straightforward process helps support cleaner internal water passages and more reliable cooling performance over time.

FAQ

Q: Will this engine flusher fit my outboard motor?
A: The rectangular ear muffs are designed to fit most common outboard motors with side water intake slots. Always check the position and size of your intakes and ensure the cups can fully cover them for proper flushing.

Q: How do I connect it to my water supply?
A: Attach the included quick‑connect fitting to a standard garden hose. Slide the rubber cups over the water intake slots, confirm a snug fit, then turn on the water before starting the engine according to the engine manufacturer's instructions.

Q: How often should I flush my outboard engine?
A: For boats used in saltwater or silty conditions, flushing after every outing is generally recommended. In freshwater, flushing after extended use or at the end of the season can help maintain cleaner internal passages.

A: Yes. The flusher is intended for use with the boat on a trailer or lift, where you can access the lower unit and connect a garden hose safely on land.

Q: Does it require any special tools to install or remove?
A: No. The spring steel frame and rubber cups are hand‑operated. Simply slide the cups into place and remove them when flushing is complete.
