The Best Advice for Any Piranha Owner: Always Carry Spare Blades.

Here's what experienced boaters know that first-timers learn the hard way: carrying spare blades beats carrying a spare prop every time.

With Piranha's modular hub design, a blade strike doesn't mean a tow or a ruined afternoon. Swap the damaged blade in minutes, right on the water, and keep going. No shop. No waiting. No expensive repair bill.

Since you can't break more blades than are on the prop, we recommend picking up a full spare blade set when you order your E-Series. You probably won't damage all three at once — but having a complete set ensures your propeller stays properly balanced and maintains the correct pitch. MacombMarineParts.com stocks matching E-Series blade sets, so add one to your cart before you check out. It's the best insurance you'll buy for a day on the water.

Why the E-Series Outperforms Standard Aluminum Props:

• Shock-absorbing blade design — engineered to absorb the impact of a propeller strike and virtually eliminate lower unit damage
• Aluminum-core center hub over-molded with high-strength composite for maximum rigidity and durability
• Modular construction — repair or re-pitch in minutes, no special tools required
• Stronger than aluminum — aerospace-grade composite that outlasts traditional metal props
• Corrosion-resistant — performs in salt and fresh water, season after season
• Saves on repair costs — replace only the blade, not the entire propeller assembly
• Made in the USA — lifetime hub assembly guarantee included

Frequently Asked Questions

1. What's included with the E-Series Complete Propeller? Your order includes one Piranha Hub Kit and one 3-Blade Set. The hub, three blades, and rear cap together form the complete propeller assembly — everything you need is in the box and ready to install on your 9.9–15HP outboard.

2. Why should I order spare blades at the same time as my propeller? Because the best time to have spare blades is before you need them. Piranha's modular system lets you swap a damaged blade in minutes on the water — but only if you have the spare with you. MacombMarineParts.com stocks matching E-Series blade sets, and ordering them together is the easiest way to make sure you're never stranded.

3. How does the E-Series protect my lower unit during a strike? The blades are engineered to flex and absorb the energy of a propeller strike, acting as a sacrificial buffer that protects your lower unit, gears, and prop shaft from damage. In most strike scenarios, only the blade is affected — not the hub, not the drivetrain — keeping your repair cost minimal and your downtime short.

4. What engines is the E-Series compatible with? The E-Series is designed for 2.5" gearcase diameter outboards in the 9.9–15HP range, available in multiple blade pitch options to match your engine and application. If you need help selecting the right pitch for your specific engine make and model, reach out to us at MacombMarineParts.com before ordering — we'll make sure you get the right fit the first time.

5. How does Piranha composite compare to a standard aluminum propeller? Piranha's aerospace-grade composite is stronger than aluminum, lighter, and completely corrosion-resistant. When an aluminum prop gets damaged, you replace the whole thing. With Piranha, you replace only the damaged blade — in minutes, on the water — at a fraction of the cost. Even on a smaller outboard, the savings on repairs over a season or two make Piranha the smarter long-term investment.
