Effective engine cooling flush - with strong water jet and garden-hose attachment
Standard garden-hose connection delivers pressurised water through the rectangular caps to mimic in-water cooling flow, with a total length of 15 inches to reach typical intake points. Cap dimensions are 4.8 inches by 3.1 inches (122mm x 78.7mm) to interface with many outboard intakes.
Clears salt, sand and debris from cooling passages while the engine idles ashore, lowering the risk of overheating and corrosion after each trip.
Secure, repeatable fit - thanks to high-elastic bracket and strong spring
High-elastic quality bracket combined with a robust spring creates tension that holds the rectangular caps in place over the intake ports during flushing. Manufacturer notes compatibility with a wide list of common outboard brands.
Stable sealing reduces the need for constant adjustment while flushing, so maintenance can be left running safely and reliably.
Fast set-up for routine maintenance - with quick garden-hose hookup and idling allowance
Designed to install in seconds using standard garden-hose fittings, allowing engines to be idled for adjustments and flushing without relaunching. Construction aims to withstand repeated use without deforming.
