Dreyoo Inboard Engine Flusher – Universal Motor Flush Kit

Keep your inboard engine running smoothly with the Dreyoo Adjustable Inboard Engine Flusher, designed for powerful and efficient cleaning. This universal motor flush kit removes sand, silt, saltwater, and minerals from your engine’s cooling system, preventing corrosion and clogging for extended service life. Ideal for both gas and diesel inboard engines, it ensures optimal performance during maintenance, winterization, or tune-ups.

Easy to install without tools, the adjustable telescoping shaft (18”–30”) reaches tight spaces effortlessly. The 5.7” suction cup creates a secure, leakproof seal to prevent water blow-by, while the marine-grade PVC and aluminum construction resists corrosion and UV damage. Compatible with all standard garden hoses and thru-hull water intakes, this flusher is a must-have for ski boats, wake boats, and more.
