Quicksilver Black Diamond 3-Blade Aluminum Propeller
Key features include a 13″ diameter and 19″ pitch with right-hand rotation. This propeller is designed for use with 40-60 HP Command Thrust and 75-125 HP Mercury engines and is constructed from aluminum with a black finish. Best for boaters seeking a balance of speed and durability in mid-range power applications. A potential limitation is compatibility only with specific engine models; confirm compatibility with your gearcase before purchasing.
Wvkeosc 13 x 19 Aluminum Propeller
This propeller features 13″ diameter, 19″ pitch, and a 15-spline, right-hand rotation. It targets Mercury engines across 40-140 HP as a reliable backup prop, emphasizing durability and fuel efficiency. Best for anglers or boaters who want a robust spare prop with straightforward installation. A caution: some listings mention generic improvements; verify spline compatibility with your exact engine model to avoid fit issues.
Meruzue OEM Upgrade 13” x 19” Aluminum
With 13″ diameter and 19″ pitch, this three-blade, right-hand rotator uses upgraded aluminum for enhanced durability. Suitable for 40-140 HP engines, and designed to improve fuel efficiency and boat speed while maintaining maneuverability. Choose this for reliable performance upgrades; best for Mercury- or similar-brand outboards. Limitation: as an OEM-style upgrade, ensure exact part number compatibility for your engine model to avoid mismatches.
Boatman 13×19 Aluminum Outboard Propeller
Designed for Mercury engines in the 40-140 HP range, this 13″ x 19″ propeller features 15-spline, three blades, and a permanent pressed hub with washer included. It emphasizes durability with upgraded aluminum and claims improved fuel efficiency and reliability. Best for boaters who want a solid OEM-matching option; use this if you need a direct replacement with good thrust. Caution: verify hub size and gearcase compatibility before purchase.
YOUNG PROPS 13 x 19 (Hub Kits Included)
This option offers 13″ diameter, 19″ pitch, three blades, 15-spline, right-hand rotation, with hub kits included. It targets Mercury engines from 40-140 HP and emphasizes durability, fuel efficiency, and performance consistency. Best for buyers who want a complete package with hub hardware included. Limitation: as with many aftermarket parts, ensure exact engine compatibility and gearcase fit before ordering.
YOUNG PROPS 13 x 19 (4-Blade) For Mercury
This variant features four blades in a 13×19 configuration with 15-spline on the RH rotation. Built for Mercury engines within 40-140 HP, it aims to increase acceleration and top-end speed, albeit with potentially more drag than a three-blade design. Best for boaters seeking stronger acceleration; choose this if you frequently run at higher RPMs. Limitation: four-blade designs can reduce top-end speed slightly on certain setups.
AQUAMAN 13×19 Propeller for Mercury
Available in multiple hub and pit combinations, this 13×19 RH propeller is made from high-strength aluminum and includes hub kits. It targets Mercury 40-140 HP engines, balancing corrosion resistance with durability. Best for owners who need a versatile propeller compatible with various hub options; avoid if your engine uses a different spline count than 15 or requires a non-standard gearcase.
Upgrade Aluminum Propeller 13×19 (Yamaha)
This propeller is engineered as a Yamaha-compatible option with 13″ diameter, 19″ pitch, right-hand rotation, and 15-spline. It uses a squeeze-cast aluminum process for improved blade strength and reliability. Best for Yamaha 50-130 HP applications requiring a direct replacement with strong forward thrust. Caution: confirm exact Yamaha model compatibility and gearcase before ordering.
Buying Guide: Key Considerations
- Engine compatibility: Verify your engine brand, HP range, and gearcase type (e.g., Mercury, Yamaha) to ensure a proper match.
- Rotation and spline: Most listings show right-hand rotation and 15-spline; confirm these match your current prop and hub kit.
- Blade count: Three blades emphasize speed and efficiency; four blades can improve acceleration but may reduce top speed depending on setup.
- Material and durability: Aluminum props are common for cost efficiency and corrosion resistance; inspect hub design and tolerances for reliability.
- Hub kits and installation: Some listings include hub kits; if not, factor in compatibility with your gearcase and seals.
Further buyer considerations
- Fuel efficiency: Upgraded metals and precise pitch can reduce RPM drag and improve fuel economy.
- Durability: Look for products with robust blade construction and reliable hub designs to minimize replacement frequency.
- Availability of spare parts: Consider propellers with readily available rebuild options or replacement blades.

It denotes a 13 inch diameter and 19 inch pitch. The diameter measures blade width, while pitch indicates how far the propeller would move in one full revolution in ideal conditions.
Some propellers include hub kits; if not, you may need to buy a compatible hub kit separately for your gearcase.
Four-blade props typically offer better acceleration and load handling, but top speed can be lower depending on engine and boat setup.
Check the engine’s HP range, splines, gearcase compatibility, and the rotation direction listed by the seller. Refer to your owner’s manual for exact specifications.
Yes. A properly matched propeller can reduce engine RPM at cruising speed, improving fuel economy and performance.
Inspect for blade damage, ensure the hub is intact, and replace the propeller if there are cracks or significant bends to prevent engine damage.
