Kit 12 is designed for 25–75hp outboards with a 3.5-inch gearcase, and is compatible with Hustler and Express Mach3 propeller housings. It’s the only hub kit in the industry backed by a \u003cstrong\u003eLifetime Warranty\u003c\/strong\u003e — including coverage even if the propeller is destroyed in a strike.\u003c\/p\u003e\n\n\u003ch3\u003eBest Use Case\u003c\/h3\u003e\n\u003cp\u003eKit 12 is the correct hub kit for boaters running Hustler or Express Mach3 propellers on 25–75hp outboards with a 3.5-inch gearcase. It’s also the smart choice for anyone replacing an older rubber-sleeve or multi-part hub system — the one-piece MasterGuard design eliminates the most common failure points found in conventional hub kits, and can be reused after most prop strikes rather than replaced. Always confirm your engine make, model, and year against the application chart before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLifetime Warranty\u003c\/strong\u003e — The only hub kit in the world with a lifetime warranty, with no restrictions for normal consumer use.
