⚡ At a Glance
- • Water Flow: Dual-feed design routes water to both intake slots for more even flushing
- • Best for: Owners of outboards or stern drives with side lower-unit water intakes
- • Not ideal for: Engines with rear-facing or top-mounted intake arrangements
Dual-feed design increases flow to both intakes for a more complete flush. Large rectangular rubber muff and spring-steel frame create a secure seal while minimising leakage.
Thorough Flushing - thanks to dual-feed design
Dual-feed design delivers water simultaneously to both intake slots, reducing dead zones and ensuring circulation through cooling passages. Flow is balanced between intakes for a more consistent rinse.
Cleaner cooling passages reduce salt and debris build-up, lowering the risk of overheating and corrosion over time.
Secure Seal and Less Mess - with large rectangular rubber muff
Large rectangular rubber muff forms a broad contact area around the intake, while the slide-on cups sit over the slots to limit splash and leakage. The wide seal reduces water loss during shore or dock flushing.
A neater flush keeps the transom drier and concentrates water where it matters, making routine maintenance quicker and tidier.
Quick Hookup and Durable Hold - with black coated spring-steel frame and male hose fitting
Black coated spring-steel frame gives rigidity and holds cups firmly in place, resisting bending. Male fitting mates with standard garden hoses for immediate connection at marinas or shorelines.
Fast, reliable attachment means less fiddling on the transom and a dependable fit across a wide range of outboards and stern drives.
