Description
Maintain your Honda outboard with ease using this OEM flush hose adapter (Honda part number 19271-ZV1-000). Designed for compatibility with 5 to 50 HP Honda outboards, this adapter provides a quick and secure connection to a standard garden hose, eliminating the need for bulky rinsing systems or improvised setups.
Constructed from lightweight, corrosion-resistant aluminium, the adapter ensures durability even in a marine environment. The precision-machined threads guarantee a positive seal, helping prevent water leakage during flushing. Its compact footprint makes it easy to install and remove, allowing routine engine rinsing without hassle.
Using the flush hose adapter helps remove salt, silt, and debris from the cooling passages of your outboard, thereby helping to maintain efficient cooling performance and reduce the risk of overheating or cavitation. It’s particularly useful after use in saltwater or muddy waterways. Ideal for boat owners who want a simple, effective, and reliable solution to flush their engine quickly between outings.
Whether you’re doing seasonal maintenance or just rinsing after a day’s run, this adapter is a practical addition to your marine toolkit.
