JSPROP Aluminum Boat Propeller 14-Spline RH Replacement Style 10 1/2X11, 3-Blade for 15–35 HP

JSPROP's OEM-style aluminum propeller is a 3-blade, right-hand 10½" x 11" unit with 14 splines designed to replace OEM parts on 15–35 HP Johnson, Evinrude and compatible OMC sterndrive engines.

This replacement prop blends a light, corrosion-resistant aluminum alloy with an anti-corrosion coating and an improved blade profile to restore thrust, acceleration and engine efficiency for small outboard and sterndrive boats. Engineered to match OEM reference numbers (765049, 763486, 765050, 778863) and fit 14-spline hubs, the prop is intended for owners who need a direct-fit spare or upgrade that’s easy to install and built for marine conditions.

How do I confirm this propeller fits my motor?

Fit depends on four key measurements: spline count, diameter, pitch and rotation. Compare those values with your current prop or owner's manual before ordering to avoid mismatches.

• Check spline: 14-tooth spline hub required.
• Confirm size: 10½" diameter and 11" pitch.
• Rotation: right-hand (clockwise) rotation.
• Horsepower range: suitable for 15–35 HP engines.

What performance changes should I expect after installing this propeller?

This aluminum prop is optimized to return reliable throttle response, good top speed and efficient rpm ranges without excessive load on the engine. While exact results vary by boat weight, gear and hull, most owners see stable acceleration and improved fuel economy compared with a damaged or heavily worn prop.

• Improved acceleration from the redesigned blade geometry.
• Balanced top-end speed with controlled engine load.
• Corrosion-resistant finish protects performance in salt or fresh water.

How durable and serviceable is the JSPROP aluminum prop?

Made from an aluminum alloy with a patented anti-corrosion coating and a pressed-in hub, the unit resists surface wear and simplifies installation or replacement. Routine inspection for dings, bent blades or hub play will keep the prop delivering reliable service season after season.

• Aluminum alloy construction for a lightweight, durable blade.
• Anti-corrosion coating extends service life in marine environments.
• Pressed-in hub design for straightforward fitment and replacement.

What should I know about installation and maintenance?

Installation is a straightforward mechanical swap when the spline, diameter and pitch match your original prop. Use the correct prop nut torque, a new cotter pin or locking device if required, and spin-check free play in the hub after mounting.

• Always match spline count and size before installing.
• Tighten to manufacturer torque and secure with appropriate fasteners.
• Inspect blades and hub regularly; repair or replace after strikes.

Who is this for: This JSPROP propeller is suited for boat owners, marine service shops and rental operators who need a dependable OEM-compatible spare for Johnson, Evinrude and OMC sterndrive outboards rated 15–35 HP. It's a practical choice for recreational anglers, small skiff owners and anyone replacing a damaged 14-spline, 10½" x 11" right-hand propeller who wants a straightforward, cost-effective option with corrosion protection and easy installation support.
