The 42\" hose gives you enough reach to drain directly into a collection jug or oil change pump without contorting around the engine. A worthwhile addition to any onboard maintenance kit for boats that are serviced at the dock or on the trailer.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eConfirm your engine's oil drain port uses 1\/2\"-20 thread before ordering — thread pitch varies by engine manufacturer and model. This kit is designed for gravity-drain oil changes; if your engine compartment doesn't allow gravity drainage, an oil extractor pump may be a better solution.
