Buying Guide
Choosing the right prop for your Yamaha 115 4-stroke involves considering several factors. Here are a few things to keep in mind:
- Material: Aluminum props are more affordable but less durable than stainless steel. Stainless steel props offer better performance and longevity but come at a higher price.
- Pitch: Pitch refers to the distance a propeller travels in one revolution. A lower pitch provides better acceleration, while a higher pitch offers higher top-end speed.
- Diameter: The diameter of the prop also affects performance. A larger diameter prop can move more water, which is beneficial for heavier boats or those used for towing.
- Number of Blades: Most props have three or four blades. Three-blade props generally offer better speed, while four-blade props provide better thrust and handling.
- Boat Type and Usage: Consider the type of boat you have and how you use it. Are you primarily fishing, waterskiing, or cruising? The right prop will depend on your specific needs.
- Engine RPM Range: Check your Yamaha 115’s recommended RPM range at wide-open throttle. The correct prop will allow your engine to operate within this range.
FAQs
Q: How do I know what prop size to get for my Yamaha 115?
A: Consult your boat’s owner’s manual or talk to a marine mechanic. They can help you determine the ideal prop size based on your boat type, engine, and typical usage.
Q: Can I use a stainless steel prop on my aluminum boat?
A: Yes, you can. Just be aware that stainless steel props are heavier and can potentially cause more wear on your boat’s drivetrain over time.
Q: How often should I replace my boat prop?
A: It depends on usage and conditions. Inspect your prop regularly for damage. Replace it if you notice any significant dents, cracks, or excessive wear.
Q: What does “pitch” mean when referring to boat props?
A: Pitch is the theoretical distance a prop travels forward in one revolution. Lower pitch gives better acceleration; higher pitch equals higher top speed.
Q: Is it hard to change a prop myself?
A: Not usually. You’ll need a prop wrench and possibly a prop puller. There are plenty of online tutorials that can guide you through the process.
