Hustler® 12.25x15 – 3-Blade Aluminum Propeller | 25–75hp (3.5" Gearcase)

Hustler® 12.25x15 – 3-Blade Aluminum Propeller

The Hustler® 12.25x15 is a high-performance aluminum propeller engineered for boaters who want stainless-steel-level performance without the stainless-steel price tag. Built using an exclusive squeeze-cast process, this 3-blade prop delivers exceptional blade stiffness, reduced flex, and improved fuel efficiency — making it one of the most capable aluminum propellers in its class.

Designed for outboards from 25–75hp with 3.5" gearcases, the Hustler® 12.25x15 is compatible with a wide range of engine brands including Coleman®, Evinrude®, Honda®, Johnson®, Mariner®, Mercury®, Nissan®, Parsun®, Suzuki®, Tohatsu®, and Yamaha®.

Key Features

• Squeeze-Cast Construction: Produces a denser, tighter grain structure than traditional die-cast aluminum — resulting in stiffer blades, less flex under load, and more efficient power transfer to the water.
• Stainless Steel Blade Geometry: Blade profiles are drawn from the same geometry used in stainless steel designs, delivering top-end speed and bow-lifting performance that rivals SS props.
• Increased Blade Surface & Cupping: Enhanced blade area and cupped trailing edges improve grip, reduce ventilation, and sharpen throttle response.
• Ultracoat™ Powder-Coated Finish: A five-step powder-coat process provides superior corrosion resistance and a durable, automotive-quality appearance that holds up in saltwater and freshwater environments.
• Large Exhaust Ports: Oversized exhaust flow pathways reduce backpressure and help maximize available horsepower.

Parts Desk Insights

Best Use Case: This prop is the go-to recommendation for mid-range pontoon boats, fishing boats, RIBs, and tiller-steered outboards in the 25–75hp range where the customer wants maximum top-end speed and strong bow lift without moving to stainless steel. The 15" pitch makes it ideal for lighter, faster hulls — if the customer is running a heavier load or wants better hole shot, step them down to the Hustler® 12x10.5 or the Hustler® 10.5x13.

Hub Kit Required: This propeller uses the 10-Series hub system only. Always confirm the customer's engine make, model, and year before recommending a hub kit. See the MasterGuard® Hub Kit – Model 26 or Model 28 as common starting points, but verify against the application chart.

Pitch Selection Tip: As a general rule, every 2" of pitch change shifts WOT RPM by approximately 200–400 RPM. If the customer's engine is over-revving at WOT, move up in pitch; if it can't reach WOT RPM range, move down.

Note: Hub installation kits are sold separately and are not included with this propeller.
