Pros & Cons
👍 Pros
- Genuine OEM manufacture ensures dimensional accuracy to Yamaha's original engineering specifications, which directly affects propeller efficiency and RPM operating range compared to aftermarket alternatives.
- Aluminum construction absorbs minor underwater strike impacts by deforming rather than transmitting peak force through the prop shaft to the gearcase, reducing the risk of more expensive internal damage.
- The 15-1/4 x 15 pitch specification provides a balanced diameter-to-pitch ratio suitable for mid-range displacement applications where neither hole-shot nor top speed is sacrificed entirely.
- OEM sourcing guarantees correct hub spline engagement geometry — aftermarket props occasionally deviate from published tolerances in ways that introduce vibration at high RPM.
- The genuine part designation means this propeller carries Yamaha's engineering validation for use with compatible engine models, rather than relying on aftermarket performance claims.
👎 Cons
- The listing provides minimal compatibility data beyond the part number, requiring the buyer to independently verify engine fitment — incorrect orders are a non-trivial risk without prior research.
- Aluminum propellers operate at lower efficiency under sustained high-speed use compared to stainless steel alternatives, delivering measurably less top-end performance in performance-oriented applications.
- Sold individually means replacement cost for a matched pair (required for counter-rotating applications) doubles, with no multi-unit pricing incentive.
- No published blade count, rake, or cup specification is provided, limiting the technical comparison a serious buyer would want when choosing between pitch options.
- Aluminum props are more susceptible to cavitation erosion over time in sandy or debris-heavy water environments compared to stainless alternatives with higher surface hardness.
Frequently Asked Questions
What does the 15-1/4 x 15 specification mean, and how does it affect my boat's performance?
The two numbers describe diameter and pitch. 15-1/4 inches is the blade tip-to-tip diameter; 15 inches is the theoretical forward travel per revolution in an ideal medium. Higher pitch moves more water per revolution, raising top speed but requiring more engine torque — dropping pitch improves hole shot and acceleration at the cost of top-end speed.
How do I verify this propeller fits my specific Yamaha outboard engine?
Yamaha recommends verifying fitment against your engine's model number and year before ordering. The listing explicitly notes "please verify your own fitment." Cross-reference part number 6G5-45941-00-EL (updated to 6G5-45941-00-00) against your engine's parts diagram or contact a Yamaha marine dealer with your engine serial number.
Why does the listing show two different part numbers (6G5-45941-00-EL and 6G5-45941-00-00)?
Yamaha periodically revises part numbers for OEM components without changing the physical part. The -EL suffix is the earlier designation; 6G5-45941-00-00 is the current superseding number. Both refer to the same propeller — either number will identify this part correctly with a Yamaha dealer.
Is aluminum an appropriate material for my use case, or should I consider stainless steel?
Aluminum propellers are lighter, less expensive, and more forgiving in strike situations — they bend rather than transmitting full impact force to the gearcase. Stainless steel delivers higher performance efficiency and durability under sustained high-RPM use but costs significantly more and transfers strike energy more aggressively. Aluminum is appropriate for most recreational and moderate-use applications.
Is this propeller sold as a single unit or in a pair?
This propeller is sold individually — one propeller per purchase. The listing explicitly states "Sold Each." Order the quantity your application requires.
