• PEACE OF MIND: Our premium boat motor muffs outboard as well as I/Os are constructed with rubber, flexible water lines and water tight seals to test, cool, winterize, warm and idle your engine before or after going out or as part of a winterizing kit.
• UNIVERSAL FIT: Our outboard motor muffs offer rotating ears and a U channel measuring 10.5" to rotate and adapt to almost any outboard motor and Inboard/Outboard I/O engines. Large ear muffs to flush away engine dirt while allowing easy flushing.
• DOUBLE SIDED: Increased water supply from two sides offers superior intake compared to old single sided boat muffs. The flexible water tight boat muffs measure 3 1/4" by 5" and bend to allow the flusher to snuggly pinch your intakes.
• STANDARD INSTALL: Our boat ear muffs outboard use connects to a standard hose with an included optional quick connect male adapter end and rubber washer. No tools needed. Use with or without additional marine salt flush kit boat parts.
