VIF 10 3/8 x 13 OEM Prop for Mercury

Model Characteristic: OEM-grade quality with good painting and speed. Designed for Mercury outboards 9.9–25HP, 10 Spline Tooth, Right rotation, 3 blades. Color: Black. Material: high-quality aluminum. This propeller aims to deliver top speed and smoother acceleration while reducing engine wear. Best for budget-conscious boaters needing a reliable OEM-style replacement with solid performance. Caution: aluminum props can wear faster in rocky waters; inspect for dings after use.
Qiclear 13 1/4 x 17 Upgrade Prop for Mercury 60–125 HP

Model Characteristic: High-quality finish with performance-oriented speed. For Mercury Outboard engines 60–125 HP, 15 Spline Tooth, Right rotation, 3 blades. Material: aluminum. The design emphasizes durability without sacrificing speed, aiming to reduce slip and improve bite. Best for mid-range to high-power Mercury setups where top-end speed matters. Caution: ensure spline count and hub kit compatibility with your specific model before purchase.
DLNIG 13 1/4 x 17-K Yamaha Prop

Applicable: Yamaha 60–130 HP. Size & Material: 13 1/4 diameter x 17-K pitch; 15 Spline Teeth; Right rotation; 3 blades. Material: high-quality aluminum. The propeller is built with OEM blade geometry and added cupping to boost bow lift, acceleration, and top speed while reducing slip. Best for Yamaha boats seeking a balance of lift and speed. Caution: verify K-pitch compatibility with your specific Yamaha model to avoid over- or under-revving.
YOUNG PROPS Stainless Steel 11 x 15 Prop for Mercury

Model Characteristic: OEM-grade prop for Mercury Outboard 40–60 HP. Size: 11 diameter x 15 pitch, 13 splines; Right rotation; 3 blades. Material: duplex stainless steel. Outstanding quality emphasizes high strength and excellent corrosion resistance in saltwater environments. Best for boats requiring durable props with extended life and consistent performance. Caution: stainless steel props are heavier; check engine mounting and gearcase compatibility to maintain proper RPM.
MiBarco 9 1/4 x 11-J Yamaha Prop

Model Characteristic: OEM-style quality for Yamaha 40–60 HP. Size: 9 1/4 diameter x 11 pitch; 8 splines; Right rotation; 3 blades. Material: high-quality aluminum. Designed with OEM blade geometry to improve bow lift, acceleration, and top speed while reducing slip. Best for lighter boats or lower HP Yamaha setups where quick planing is desired. Caution: smaller diameter may reduce stern lift on heavier craft; confirm engine compatibility before purchase.
Buying Guide: Key Considerations For Outboard Propellers And Guards
- Engine compatibility: Match diameter, pitch, and spline count to your engine horsepower and model. Using the wrong pitch or spline count can cause cavitation or RPM issues.
- Material choice: Aluminum props are affordable and light; stainless steel props offer higher strength and corrosion resistance but add weight and cost. Choose based on water type (salt vs freshwater) and operating conditions.
- Blade design and cupping: More cupping increases lift and improves acceleration; less cupping favors top speed. Consider your typical boating conditions (flat water vs choppy water).
- Durability vs maintenance: Stainless steel lasts longer but requires proper care. Aluminum props are easier to repair or replace in shallow, rocky areas.
- Protection options: Prop guards (polypropylene or other plastics) protect propellers in shallow or cluttered waters. Guards add protection but can affect performance slightly due to weight or drag.
- Installation considerations: Ensure hub kits and hardware are compatible with your motor. Verify correct right-hand versus left-hand rotation for your prop.
FAQ
- What does “right rotation” mean in a propeller?
– It refers to the propeller turning clockwise when viewed from the prop shaft. Use the correct rotation to match your engine and gearcase. - Can I use a different brand prop on my Mercury motor?
– Yes, many aftermarket props are designed as compatible upgrades, but confirm spline count, diameter, and pitch to avoid RPM issues. - Are stainless steel props worth the extra cost?
– If you operate in saltwater or require higher strength and longer life, stainless steel can be advantageous; for casual freshwater use, aluminum may suffice. - What is the advantage of a prop guard?
– Guards reduce the risk of strikes in shallow water, protect prop blades, and minimize entanglement with debris. They may marginally affect performance. - How do I choose the right pitch?
– Higher pitch idealy increases top speed but requires more RPM; lower pitch improves acceleration and planing; select based on boat weight and engine horsepower. - Do these props come with hub kits?
– Some listings include hub kits; always verify what is included and whether you need an additional hub kit for your motor.
