Piranha Propellers Propulsion Kit D-Series 3-Blade

Piranha Propellers Propulsion Kit D-Series 3-Blade

When you're running an 18–30HP outboard on a 2.75" gearcase, a propeller strike can end your day just as fast as it can on a bigger rig. The difference is what you do next. Piranha created the D-Series Propulsion Kit to give smaller-outboard boaters the same on-water backup system trusted by serious boaters across the entire Piranha lineup — a reserve blade set, the tools to swap it, and a bag to keep it all organized and ready to go.

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

Why the Propulsion 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 D-Series Propulsion 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.

It's the most complete on-water backup plan available for 18–30HP outboard boaters — and it fits in a bag.

Why the D-Series Outperforms Standard Aluminum Props:

• 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 D-Series Propulsion Kit?
The kit includes one Piranha Hub Kit, two full 3-Blade Sets, a Floating Prop Wrench Kit, and a Self Draining Gear Bag. Together, these give you a complete on-water repair system — everything you need to swap a damaged blade and get back underway, all in one organized package.

2. 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.

3. How does the D-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 D-Series Propulsion Kit compatible with?
The D-Series is designed for 2.75" gearcase diameter outboards in the 18–30HP range. Note: does not fit Evinrude/Johnson "Bigfoot", Commercial Gearcase, "Pleasure", or "High-Thrust" models. Mariner (Yamaha) fitment: 25HP ('80–'84), 28HP ('76–'79), and 30HP ('79–'90). If you need help confirming fitment for your specific engine, reach out to us at MacombMarineParts.com before ordering.

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. The Propulsion Kit takes that advantage further by giving you the tools and spare blades to do it right, every time.
