JSPROP Aluminum Boat Propeller 10.3x13, 10.1X13 Right‑Hand 14‑Spline for Johnson Evinrude OMC — 3‑Blade, Corrosion‑Resistant

JSPROP's OEM upgrade aluminum propeller is a 3-blade, right‑hand 14‑spline replacement (10.3" diameter × 13" pitch) designed to fit Johnson/Evinrude/OMC stern drives for 15–35 HP engines.

This high‑quality replacement propeller matches several OEM part numbers and is engineered as a direct-fit upgrade for smaller outboards and stern drives. Constructed from an aluminum alloy with a patented anti‑corrosion finish and a pressed‑in hub, it balances durability with light weight to restore propulsion, acceleration and handling for recreational and workboats. Before ordering, confirm your current propeller's diameter, pitch, spline count and rotation to ensure compatibility.

How does this propeller improve performance on my 15–35 HP outboard?

The JSPROP upgrade is sized and pitched to recover lost speed and responsiveness that comes from worn or damaged OEM props. Its three blades and factory-balanced form help deliver consistent thrust through acceleration and cruising RPMs without increasing vibration.

• 10.3" diameter × 13" pitch tailored for 15–35 HP range
• Three-blade profile optimized for acceleration and steady top speed
• Factory-balanced to reduce vibration and shaft wear
• Pressed-in hub simplifies fit and prevents slippage under load

Will this fit my Johnson, Evinrude, or OMC engine?

This propeller is made to replace several OEM numbers and fits many Johnson/Evinrude/OMC applications that use a 14‑tooth spline and a right‑hand rotation. Match your engine’s required diameter, pitch, and spline count to the prop specifications to confirm fitment.

• Compatibility: fits 15–35 HP outboards and stern drives
• Splines: 14 tooth spline hub (confirm against your splined shaft)
• Rotation: right‑hand (clockwise when viewed from stern)
• OEM reference numbers: 765049, 763486, 765050, 778863 (verify before purchase)

What materials and protections are used to extend service life?

JSPROP uses a corrosion-resistant aluminum alloy and applies a patented anti‑corrosion coating to protect the blade surfaces from salt, fresh water and routine wear. The lightweight metal reduces load on the lower unit while maintaining blade stiffness for efficient thrust.

• Aluminum alloy construction for strength and reduced weight
• Patented anti‑corrosion finish to slow surface degradation
• Improved blade geometry for durability and consistent performance
• Black coating for added protection and reduced visual wear

How simple is installation and what should I check before fitting?

The propeller arrives ready to install with a pressed‑in hub that makes mounting straightforward for DIYers and mechanics. Still, you should verify diameter, pitch, spline count and rotation to ensure correct engagement and avoid cavitation or mechanical issues.

• Press‑fit hub for quick, secure installation
• Confirm 10.3" diameter × 13" pitch and 14-spline match
• Right‑hand rotation—ensure it matches your engine’s direction
• Inspect shear pin and prop nut hardware during installation

Who is this for: Boat owners and fleet operators who need a cost‑effective, OEM‑style replacement for worn or damaged props on Johnson, Evinrude or compatible OMC 15–35 HP outboards and stern drives. It’s well suited to recreational pilots who want predictable acceleration and stable cruising, mariners on a budget looking for reliable longevity, and service shops that require a ready‑to‑fit aluminum prop with anti‑corrosion protection. Always verify the prop specifications and OEM reference numbers before purchase to guarantee correct fit and safe operation.
