World Leader in Recreational Boat Propellers


Piranha Propellers

The Piranha modular design allows for blades to be replaced due to damage or to be re-pitched for performance. The key to the patented Piranha boat  propeller is the hub. The center hub is made from a high-strength aluminum core, over molded with our specially-formulated composite material.

The Piranha blades are designed to absorb the shock of a propeller strike, which virtually eliminates lower unit damage. The Piranha hub is so strong that it is guaranteed for life, “you damage it, we will replace it.” The Piranha design also eliminates spun propeller hubs.

The replaceable blades are manufactured from a specially formulated high-strength aerospace composite material. The manufacturing process is so precise, that the blade shape and pitch distribution is superior to Stainless Steel and Aluminum. Blade balance is no longer a problem as the Piranha Propeller blades are balanced to 2 times the industry standard. The precise balancing reduces lower unit damage caused by vibration.

Repairing or replacing lower units is expensive. The Piranha propeller is so effective in reducing or even eliminating damage, some insurance companies will even offer discounts on premiums. A propeller is a critical component to the performance of a boat. Damaged propellers will not only degrade performance, but can cause excessive wear on the lower unit. Spare Piranha blades are easily stored, and replacement of a damaged blade only takes a few minutes. With the replacement blades on hand, it is simple to restore a damaged propeller to factory new specifications.

Shopping for a quality outboard propeller can be extremely challenging. Propeller designs come in a variety of sizes and configurations. The support team at Piranha is available to assist in making the optimum propeller choice for your outboard or sterndrive. Piranha Propellers extensive product line will fit all sterndrive and outboard manufacturers from 6 to 280 HP.

Piranha Props are made in the USA (Jackson, CA) and are available from 9.9 to 280 HP for most outboard and I/O manufacturers.

They also come in several pitches so you can get the performance you want. They’ll also ship you out loaner blades of different pitches so you can find the one that works best.

If you fish high elevation lakes, you can buy different pitched blades so that you don’t lose speed — and then easily switch back when you come back down to the flat lands! Very cool! Read More

One of the all time best boating gadgets: The Piranha Prop

At the just completed International Sportsmen’s Expo, I saw all kinds of cool goodies…but none more awesomely useful than the line of Piranha Props! Made of a high tech aerospace composite material, the modular design of the props is brilliant. These props can take a serious beating and not break. If you do hit something, you’ll get some dings and scratches but the blade won’t bend…meaning your prop balance will stay intact. Read More
