Boat maintenance tool designed to flush outboard cooling systems quickly and reliably, JT-HLM Marine Boat Rectangular Outboard Motor seals around water intakes to rinse away salt and deposits. Peace of mind follows from protecting engines after saltwater use and making post-trip care straightforward. Is adding a dedicated flusher to weekend maintenance routine worthwhile?
⚡ At a Glance
- • Flushing Performance: Seals around intake and directs fresh water to remove contaminants
- • Best for: Boat owners who rinse engines regularly after freshwater or saltwater outings
- • Not ideal for: Outboards with non-standard inlet shapes or dimensions outside cap range
Designed to attach to a garden hose and seal around outboard water intakes for effective cooling-system flushing. A high-elasticity bracket with 10-inch arms helps form a secure fit and withstand repeated use.
Effective Saltwater Rinse - thanks to rectangular cap and sealed fit
Rectangular cap, sized at 4.85 inches by 3 inches (123mm by 76.7mm), seals around typical outboard water intakes and channels hose water into the cooling passages. The sealed fit allows the engine to be idled while fresh water circulates to dislodge salt and deposits.
Fresh water flushes contaminants from the cooling system, helping to reduce corrosion and extend engine life. Regular rinsing after saltwater trips keeps internals cleaner and maintenance needs lower.
Quick, tool-free setup - with garden-hose compatibility and simple bracket
Quick installation links directly to standard garden hoses and secures with a high-elasticity bracket that resists deformation. The 10-inch (256mm) flush arms provide reach and leverage to position the cap over the inlet.
Rapid connection and straightforward fitting make post-trip flushing an easy part of a routine, saving time and eliminating fiddly adaptors. Suitable for onshore or slip-side use where a hose is available.
Wide manufacturer fit - thanks to adaptable shape and bracket design
Cap shape and elastic bracket accommodate common inlet layouts from a range of brands, listed as Johnson/Evinrude, Mercury, Yamaha, Chrysler, Force, Honda, Nissan, Suzuki, and Tohatsu. Design allows idling for engine adjustments while water circulates.
Compatibility with many major outboard makes the flusher a versatile choice for owners with different engines or for marinas servicing multiple brands. Allows safe idling for testing and minor adjustments during flushes.
