At 10.8\" diameter and 12\" pitch, this three-blade design is tuned for top-end speed and strong bow lift — making it a natural step up from aluminum for boaters who want to get more out of their mid-range outboard.\u003c\/p\u003e\u003cp\u003eCast from Turning Point's proprietary TP17™ stainless steel alloy — formulated with 20% higher chromium content than standard stainless — the Express Mach3® delivers superior corrosion resistance, a high-gloss finish, and blade strength that holds up where aluminum flexes. The result is a stiffer, faster prop that maintains its geometry under load for consistent, efficient performance.\u003c\/p\u003e\u003cp\u003eOversized exhaust ports reduce backpressure and allow more power to reach the water. Performance-tuned pitch and rake angles are dialed in for the 25–75hp power band, making this prop well-suited to pontoons, fishing boats, RIBs, and tiller-steer applications in this range.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter x Pitch:\u003c\/strong\u003e 10.8\" x 12\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlades:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e TP17™ proprietary stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation:\u003c\/strong\u003e Right-hand (standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine fit:\u003c\/strong\u003e 25–75hp outboards with 3.5\" gearcase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub system:\u003c\/strong\u003e 10 Series (installation\/hub kit required — sold separately)\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\u003eWeight:\u003c\/strong\u003e 3.2 kg (7.0 lbs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 31301212\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eThis prop is the right choice for boaters running a 25–75hp outboard with a 3.5\" gearcase who want a genuine performance upgrade over their stock aluminum prop. The 10.8 x 12 pitch is well-suited to lighter hulls where top-end speed is the priority. If you're running heavier loads or need more mid-range pull, consider a lower-pitch option in the Express Mach3® line. For boaters not ready to move to stainless, the Hustler® aluminum props for this gearcase size offer a strong value alternative.\u003c\/p\u003e\u003ch3\u003eCompatible Aluminum Alternatives (3.5\" Gearcase)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-12x10-5-3-blade-aluminum-rh-rotation-25-75hp-3-5-gearcase\"\u003eHustler® 12 x 10.5 – 3-Blade Aluminum, RH Rotation | 25–75hp\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-10-125x15-3-blade-aluminum-rh-rotation-25-75hp-3-5-gearcase\"\u003eHustler® 10.125 x 15 – 3-Blade Aluminum, RH Rotation | 25–75hp\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/hustler-propeller-10-375x14-3-blade-aluminum-rh-rotation-25-75hp-3-5-gearcase\"\u003eHustler® 10.375 x 14 – 3-Blade Aluminum, RH Rotation | 25–75hp\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRequired Hub Kit (10 Series)\u003c\/h3\u003e\u003cul\u003e\n\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\n\u003cli\u003e\u003ca href=\"\/products\/turning-point-propellers-masterguard-installation-kit-13-11300301\"\u003eMasterGuard Installation Kit 13 (11300301)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/turning-point-propellers-masterguard-installation-kit-11-11300101\"\u003eMasterGuard Installation Kit 11 (11300101)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eAlways verify the correct hub kit number for the customer's specific engine make, model, and year using the Turning Point application chart — this prop uses 10 Series kits only, and the kit number varies by engine. The 10.8 x 12 pitch is on the lower end of the Express Mach3® range for this gearcase, making it a good fit for lighter, faster hulls targeting WOT RPM at the top of the engine's recommended range. If the customer is comparing this to an aluminum prop, the performance gap is real but modest at around 0.5–1 MPH — the primary advantage of stainless is durability and blade stiffness, not outright speed. TP17™ alloy also holds up significantly better in strike scenarios compared to standard stainless.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51215112044580,"sku":"708-31301212","price":593.13,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/708-31301110.jpg?v=1786150337","url":"https:\/\/marisolmarine.com\/products\/express-mach3-propeller-10-8x12-3-blade-stainless-steel-rh-rotation-25-75hp-3-5-gearcase","provider":"Marisol Marine Company","version":"1.0","type":"link"}
