Piranha Propellers Performance Kit A-Series 3 Blade

Piranha Propellers Performance Kit A-Series 3 Blade

When you're running a 120–260HP I/O or 150–250HP outboard on a 4.5" gearcase, a propeller strike can end your day in an instant. The difference is what you do next — and how well your boat performs before it ever happens. Piranha created the A-Series Performance Kit to give serious boaters the complete package: a full on-water backup system plus a Hydrofoil Stabilizer that puts your boat on plane faster and keeps it there.

The modular design makes changing damaged blades a simple 5-minute task. No shop. No tow. No ruined day. Backed by a lifetime hub assembly guarantee and proudly Made in the USA — and MacombMarineParts.com has it in stock and ready to ship.

Additional Information

What Makes the Performance Kit Different: The Hydrofoil Stabilizer

The Performance Kit includes everything in the Propulsion Kit — plus a Piranha Hydrofoil Stabilizer that bolts directly to the anti-ventilation plate on your drive. The hydrodynamic lift it generates provides useful stern lift, helping your boat get on plane faster and usually at a lower RPM. That means less time digging in at launch, easier water skiing pull-ups, and better performance when you're running heavily loaded.

If you want the backup plan and a performance upgrade in one box, this is it.

Why the Performance Kit Beats a Spare Prop

You've heard the advice: carry a spare prop. But if you run a Piranha, there's a better way — carry spare blades, the tools to swap them, and a bag to keep it all together. That's exactly what the A-Series Performance Kit gives you.

With Piranha's modular hub design, a blade strike doesn't mean a tow or a wrecked afternoon. Swap the damaged blade in minutes, right on the water, using the included floating prop wrench — then stow everything back in the self-draining gear bag and keep going. The kit includes two full blade sets, so you can ensure the propeller stays properly balanced and maintains the correct pitch no matter what the water throws at you.

Why the A-Series Outperforms Standard Aluminum Props:

• Hydrofoil Stabilizer included — bolts to your anti-ventilation plate for faster plane, better lift, and easier heavy-load performance
• HydroBites technology — precision ridges built into every blade that improve hole shot, reduce vibration, and control ventilation in tight turns
• Shock-absorbing blade design — engineered to absorb the impact of a propeller strike and protect your lower unit, gears, and prop shaft from damage
• Aluminum-core center hub over-molded with high-strength aerospace composite for maximum rigidity and durability
• Stronger than aluminum — aerospace-grade composite that outlasts traditional metal props in salt and fresh water
• Corrosion-resistant — no rust, no pitting, season after season
• Repair or re-pitch in minutes — no special tools required (wrench included in kit)
• 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 in the A-Series Performance Kit?
The kit includes one Piranha Hub Kit, two full 3-Blade Sets, a Floating Prop Wrench Kit, a Self Draining Gear Bag, and a Hydrofoil Stabilizer. Together, these give you a complete on-water repair system plus a performance upgrade — everything you need in one organized package.

2. What does the Hydrofoil Stabilizer do?
The Hydrofoil Stabilizer bolts to the anti-ventilation plate on your drive and generates hydrodynamic lift at the stern. This helps your boat get on plane faster — usually at a lower speed and RPM — which is especially useful when running heavily loaded or pulling up water skiers. It's a meaningful performance upgrade that requires no drilling or permanent modification.

3. Why does the kit include two blade sets instead of one?
Because you can't break more blades than are on the prop — but having a full spare set ensures your propeller stays properly balanced and maintains the correct pitch after a repair. Two sets means you're covered for multiple incidents, and you'll never be caught short on the water.

4. How does the A-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.

5. What engines is the A-Series Performance Kit compatible with?
The A-Series is designed for 4.5" gearcase diameter applications: 120–260HP I/O and 150–250HP outboards. Volvo Penta fitment requires long shaft only — verify rotation direction before ordering.
