Quick Buying Guide: What to Look for in a Propeller for Yamaha 115 4-Stroke
Choosing the right propeller for your Yamaha 115 4-stroke is the key to unlocking better speed, fuel efficiency, and overall performance.
But with so many options available, how do you know which one is the best fit for your boat? Don’t worry – we’ve broken it down, so you can make a confident decision.
1. 3-blade vs 4-blade propeller for Yamaha 115
One of the first choices you’ll need to make is whether you want a 3-blade or 4-blade propeller. Each has its advantages, depending on how you use your boat.
3-Blade Propeller – Best for Speed & Efficiency
- Faster top speed.
- Ideal for cruising & general boating
- Better fuel efficiency
Most of the Yamaha 115 4-stroke owners tend to use a 3-blade propeller. The reason is the great speed, unmatched performance, with better fuel economy. If your preference is fishing or enjoying casual boating, a 3-blade propeller is likely your best bet.
4-Blade Propeller – Best for Acceleration & Control
- Stronger hole shot (faster acceleration)
- Ideal for watersports, towing, or heavy loads
- Better handling in rough water
If you often carry heavy loads, tow wakeboarders, or a boat in rough water, a 4-blade propeller gives you more grip and better acceleration. However, the trade-off is reduced top speed.
2. Pitch & Diameter – What They Mean for Speed & Power
Your propeller’s pitch and diameter directly impact your boat’s speed, acceleration, and fuel efficiency. Here’s how.
Pitch
Pitch is the distance a propeller moves forward per full rotation. A higher pitch increases speed but lowers acceleration, while a lower pitch improves acceleration but slightly reduces top speed.
Best Pitch for Yamaha 115 4-Stroke:
- 13″-15″ pitch: Best for quick acceleration, heavy loads, and watersports.
- 17″-19″ pitch: Best for higher top speeds and better fuel efficiency.
Quick Tip: If your engine struggles to reach 5300-6300 RPM (Yamaha’s recommended range), you may need to adjust your propeller’s pitch.
Diameter
Diameter is the width of the circle created by the propeller blades’ rotation. It affects how much water the propeller pushes.
- Larger diameter = More power & grip (good for heavy loads).
- Smaller diameter = Faster top speed & efficiency.
3. Aluminum vs. Stainless Steel Propellers
The material of your prop matters! It affects durability, cost, and performance. Here comes their detailed performance-
Aluminum Propeller – Affordable & Lightweight
- Lightweight & easy to replace
- Budget-friendly option
- Ideal for casual boating and everyday use
Most Yamaha 115 4-stroke propellers are aluminum because they are affordable and work well for general boating. However, they are weaker than stainless steel and may wear out faster.
Stainless Steel Props – Durable & High Performance
- Better acceleration & fuel efficiency
- Stronger & lasts longer than aluminum
- Ideal for high-speed boating & performance enthusiasts
Stainless steel props are more expensive but extremely durable. If you want the best long-term investment and maximum speed, stainless steel is the way to go.
4. Best Propeller Size for Yamaha 115 4-Stroke (Ideal Specs)
If you want to get the most out of your Yamaha 115 4-stroke, choosing the right propeller size is crucial. There isn’t a one-size-fits-all answer, but based on Yamaha’s recommendations and real-world performance, the ideal propeller size for the Yamaha 115 4-stroke falls within these ranges:
- Diameter: 13″ – 14″
- Pitch: 13″ – 19″
The right size depends on your boating style:
1. For acceleration and watersports, a 4-blade propeller with a 13”-15” pitch is ideal. This setup provides a better hole shot, better control, and stronger towing power.
2. For speed and fuel efficiency, a 3-blade propeller with a 17”-19” pitch is ideal. This configuration ensures top-notch speed and reduced fuel consumption.
3. For General Cruising & Fishing, a 3-blade aluminum propeller with 15”-17” pitch is perfect. It provides a great balance of speed, efficiency, and smooth handling.
Quick Tip: Yamaha recommends keeping your RPM range between 5300-6300 for optimal perffishing. If your RPMs are too low, go for a lower pitch. If they’re too high, choose a higher pitch.
FAQs
What’s the fastest Yamaha 115 4-stroke propeller?
