If you're running a Hustler® prop in this power range, this is the hub kit you need — and it's the only hub kit in the industry backed by a Lifetime Warranty.\u003c\/p\u003e\u003cp\u003eUnlike conventional two-piece sleeve-and-spline or pressed-rubber hub systems, MasterGuard uses a patented one-piece design combining durable marine bronze splines with a glass-filled nylon over-mold. This eliminates the cracking, spinning, and vibration failures common in multi-part hub systems, and provides genuine lower unit protection on prop strikes.\u003c\/p\u003e\u003cp\u003eThe hub is reusable after most prop strikes. If the prop housing is damaged, you only need to replace the housing — not the entire hub — saving significantly on replacement costs over time.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e 20 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Number:\u003c\/strong\u003e 21 (Part: 11200100)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine fit:\u003c\/strong\u003e 9.9–35hp outboards with 3\" gearcase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible brands:\u003c\/strong\u003e Coleman®, Evinrude®, Honda®, Johnson®, Mariner®, Mercury®, Nissan®, Parsun®, Suzuki®, Tohatsu®, Yamaha®\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible props:\u003c\/strong\u003e Hustler® and Express Mach3® housings (20 Series)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub construction:\u003c\/strong\u003e Marine bronze splines with glass-filled nylon over-mold (one-piece)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Lifetime (consumer use)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Hub assembly, prop nut spacer, installation instructions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 218g (0.48 lbs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 708-11200100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eThis kit is the correct choice for boaters running a Hustler® aluminum prop on a small outboard in the 9.9–35hp range with a 3\" gearcase. It's also the smart long-term buy for anyone who wants to reduce the cost of prop strike replacements — once the hub is installed, future prop housing swaps are significantly less expensive than replacing a full propeller assembly.\u003c\/p\u003e\u003ch3\u003eCompatible Propellers (20 Series)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-10-125x13-3-blade-aluminum-rh-rotation-9-9-35hp-3-gearcase\"\u003eHustler® 10.125 x 13 – 3-Blade Aluminum, RH Rotation | 9.9–35hp\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-10-375x13-3-blade-aluminum-rh-rotation-9-9-35hp-3-gearcase\"\u003eHustler® 10.375 x 13 – 3-Blade Aluminum, RH Rotation | 9.9–35hp\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-10-5x11-3-blade-aluminum-rh-rotation-9-9-35hp-3-gearcase\"\u003eHustler® 10.5 x 11 – 3-Blade Aluminum, RH Rotation | 9.9–35hp\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-10-375x11-3-blade-aluminum-rh-rotation-9-9-35hp-3-gearcase\"\u003eHustler® 10.375 x 11 – 3-Blade Aluminum, RH Rotation | 9.9–35hp\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRelated Hub Kits\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"\/products\/masterguard-installation-kit-12-hub-kit-for-25-75hp-outboards-3-5-gearcase\"\u003eMasterGuard Installation Kit 12 – 25–75hp Outboards (3.5\" Gearcase)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eAlways verify engine compatibility using the Turning Point application chart before ordering — the kit number varies by engine make, model, and year. This is Kit 21 (11200100); confirm it matches the customer's engine before completing the order. The Lifetime Warranty applies to consumer use only and excludes extreme commercial applications — direct customers to the manufacturer's warranty page for full terms. Hub is reusable after most prop strikes; if the hub is damaged beyond reuse, it is still covered under warranty for consumer use.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51215111979044,"sku":"708-11200100","price":63.94,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/708-11300101_pkg_d47af391-3376-4b64-8f8a-d2d76d73562f.jpg?v=1786150446","url":"https:\/\/marisolmarine.com\/products\/masterguard-20-series-hub-kit-9-9-35hp-outboard-3-gearcase-installation-kit-21","provider":"Marisol Marine Company","version":"1.0","type":"link"}
