Additional Information

Why Carry Spare Blades?

You've heard it before — always carry a spare propeller. With Piranha, we take it further: carry spare blades. Since you can't break more blades than are on the prop, a full spare set ensures your propeller stays properly balanced and maintains correct pitch. Whether you run 3-blade or 4-blade boat propellers, you'll be ready for anything.

Key Benefits

• Stronger than aluminum
• Repair or re-pitch in minutes
• Does not corrode
• Saves on repair costs
• Made in the USA

Frequently Asked Questions

What engines is this kit compatible with?
This kit is designed for 9.9–15 HP outboard engines with a 2.5" gearcase diameter. It also fits Mercury/Mariner 6 HP, 6.6 HP, and 8 HP models. It does NOT fit Evinrude/Johnson/Mercury "Bigfoot", Commercial Gearcase, "Pleasure", or "High-Thrust" gearcases.

How long does a field blade replacement take?
Blade swaps are designed to take approximately 5 minutes using the included Floating Prop Wrench Kit — no special tools or boat ramp required.

Why does the kit include 2 blade sets instead of 1?
A full spare set (all blades replaced at once) keeps your propeller properly balanced and maintains correct pitch. Replacing only one damaged blade can throw off balance and reduce performance.

Will the blades corrode in saltwater?
No. Piranha propeller blades are engineered to resist corrosion, making them suitable for both freshwater and saltwater use.

Are Piranha blades stronger than aluminum props?
Yes. Piranha's composite blade material is stronger than aluminum, which means it's more resistant to impact damage from rocks, debris, and shallow-water hazards.

Does this kit work with both 3-blade and 4-blade configurations?
This specific kit is a 3-blade configuration. Piranha also offers 4-blade kits — check our full propeller catalog for the right fit for your engine and hull.

What's included in the Floating Prop Wrench Kit?
The Floating Prop Wrench Kit contains the tools needed to remove and install Piranha blades in the field. It's designed to float if dropped overboard, so you won't lose it during a water-side repair.

Can I buy replacement blades separately later?
Yes. Piranha replacement blade sets are available separately, so you can restock without purchasing a full kit again.
