The three blades are designed to optimize hydrodynamic efficiency, improving fuel economy and overall response for freshwater and some saltwater usage. The right-hand rotation aligns with many standard outboards. Caution: ensure exact OEM compatibility with your engine model before purchase to avoid fit issues. Best for boaters wanting lighter weight with dependable durability.
OEM Upgrade Aluminum Propeller 11 3/4×17 RH
Best for Johnson/Evinrude/BRP 40–55HP engines requiring an OEM-aligned profile. The propeller features a 11 3/4 diameter, 17 pitch, 13-spline tooth, and three blades in a black finish with a robust aluminum construction. It emphasizes corrosion resistance and a smooth transfer of power. Caution: color and finish are cosmetic refinements; verify exact OEM part number 3868410386841 matches your model. Choose this if you need a close OEM substitute that maintains performance and durability.
YOUNG PROPS 11 3/4 x 17
Best as a reliable backup prop for BRP, Johnson, Evinrude OMC SternDrive setups in the 40–50HP range. It features 11 3/4 diameter, 17 pitch, 13-spline, and right-hand rotation with three blades. The design emphasizes durability and efficiency with robust aluminum construction. Caution: for optimal performance, confirm the tooth count and spline match your gearcase. Choose this if you want a dependable spare prop with solid performance.
PWCMAN 11″ x 17″ 3-Blade RH Propeller
Best for Honda Outboards in the 35–60HP range. This 11 x 17 propeller uses a 13-spline tooth and three blades, with right-hand rotation. It is designed for precise fit and maximum efficiency on Honda BF35–BF60 series. Caution: intended for Honda gearcases with the specified spline arrangement. Choose this if you own a Honda outboard and need a purpose-built propeller with reliable aluminum construction.
PropelTech Aluminum Upgrades
Best for Honda 35–60HP engines needing a robust upgrade. The propeller is 11 inches in diameter with a 17-inch pitch and 13-spline, three blades, right-hand rotation. It emphasizes corrosion resistance, precision machining, and heat treatment for smoother water flow and improved propulsion efficiency. Caution: verify spline compatibility with your gearcase before ordering. Choose this if you want a budget-friendly aluminum option with solid performance characteristics.
Buying Guide
What to consider when selecting an 11 3/4 x 17 propeller:
- Engine compatibility: Confirm the spline count (13-spline) and gearcase fit for your engine’s make and model.
- Rotation direction: Most outboards use right-hand rotation; ensure you select RH for standard setups.
- Material and durability: Aluminum props balance cost and durability; consider coatings and hub design for vibration reduction.
- Number of blades: Three blades offer a balance of speed and control; four blades can provide more bite in rough water but reduce top speed slightly.
- Intended environment: Freshwater vs. saltwater exposure affects corrosion considerations and maintenance needs.
- OEM vs. aftermarket: OEM substitutions may match exact geometry; aftermarket options can vary in finish but deliver similar performance if specs align.
Frequently Asked Questions
- Q: How do I know if 11 3/4 x 17 is the right size for my engine? A: Check your existing propeller’s diameter and pitch, plus the engine’s recommended RPM range and spline count.
- Q: What does 13-spline mean? A: It refers to the spline count on the propeller shaft, critical for proper mating with the gearcase.
- Q: Is a three-blade propeller better than a four-blade propeller? A: Three blades typically offer higher top speed and quicker acceleration; four blades improve acceleration and hold but can reduce top speed.
- Q: Can I use a propeller designed for BRP Johnson Evinrude on a Honda engine? A: Only if the specifications (diameter, pitch, spline count, and rotation) match your engine’s gearcase and manufacturer recommendations.
- Q: Do propellers need maintenance? A: Yes. Rinse after use, inspect blades for damage, and check hub integrity to prevent vibration or slippage.
- Q: What is the risk of using the wrong propeller? A: Mismatched props can increase RPM beyond safe limits, reduce efficiency, and cause engine wear or overheating.
