Johnson & Evinrude Outboard Engine Flushers

Regular engine flushing is one of the simplest ways to protect your cooling system from salt, sand, and mineral buildup. Our selection of engine flushers—from universal “ear muffs” to inboard/sterndrive flush kits—helps you clean outboards and sterndrives quickly at the ramp, in the driveway, or after storage.

What Muffs Do You Need?

• Dual-Feed Ear Muffs: Two inlets deliver higher water volume for better coverage at idle—ideal for mid- to high-HP outboards and warm climates.
• Single-Feed Ear Muffs: Simple, budget-friendly option for small engines and freshwater use.
• Cup Shapes & Sizes: Round and rectangular cups fit typical lower-unit intakes; heavy-duty frames hold tight for stable water flow.
