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.

Many of you have read my articles over the last couple of years and probably think that this website is how I make my living, although that would be fantastic, the truth is that I pay my bills by working as a police officer on a small Island in the Great Lakes. Part of my duties as a police officer is operating a 22’ Pursuit, which we use for enforcement on the water or, as is most often the case in this heavy boating community, search and rescue operations. During search and rescue operations we must take our boat into areas that we would prefer not to go but, unfortunately, we must go where the situation dictates, not where we feel comfortable. We’ve recently had a few prop strikes, on one occasion doing significant damage to our lower-unit. As one of the people that are responsible for the boat’s maintenance, I was getting strong pressure by the person that cuts the checks for the boat’s repairs to abandon the stainless prop in favor of aluminum. On the other side of the argument was the boat’s other operator, who was strongly advocating keeping the stainless for performance purposes. As I pondered how to bridge this gap, I recalled stumbling on to Piranha props a few months earlier while researching other boating items. Piranha promised great performance, a low cost, and most importantly, the ability to make a prop repairs while still on the water; if accurate, my problems were solved.
After doing a little more research, I made the decision to go ahead and give it a try. My first step was to make contact with Laura at Piranha Props. Laura asked me some basic questions about the boat and motor and recommended the proper prop. Laura also recommended buying the kit that contained the hub, two sets of blades, a floating prop wrench, and a mesh bag to contain it all. When I accepted her recommendation, Laura told me something else that was very reassuring; she would send me two different pitch blades (an 18 and 20 pitch) and if we don’t like them, send them back and they’ll send us another set to try.
When the prop arrived, I was left feeling somewhat underwhelmed; it was very light and felt like a plastic child’s toy. I was dreading showing it to my co-workers but I had to put my big boy pants on and own up to my decision; luckily my coworkers were remarkably accepting of my prop exploration.
Several days later, I finally got around to mounting the prop on the boat; to my disappointment, the prop bottomed out on the lower unit and wouldn’t spin freely when tightened down. I gave Piranha a call so I could get the proper propeller and send back the one they had sent, however they told me something I hadn’t expected; since it is made of a composite, if it was rubbing just slightly, I could sand the hub down. This would save me considerable hassle, so I hit the disc sander and had the prop, complete with 18-pitch blades, mounted and spinning freely within minutes.
Due to rough weather blowing in, I was not able to test the prop on that day. But, just a couple of days later, I received a request for assistance from the U.S. Coast Guard to assist in the recovery of a drowning victim; it seems that the USCG boat was too large to get in shallow and they needed someone that could. I thought, “What better circumstance to test a prop designed to absorb strikes than this situation,” so I dropped the boat in the water and headed out.
Immediately after hitting the open water, I opened the boat up. The boat came out of the water and up on plane just as well as it did with the19-pitch, 3-blade, 15.25”, stainless prop. When I reached WOT (5,100 RPM) the boat was cruising along at 39 mph, a loss of about 1 to 2mph compared to the stainless prop. Considering the smaller diameter and lower pitch of the Piranha, a loss of only 1 to 2mph was a small price to pay for the knowledge that if I have a catastrophic prop strike, my total repair cost would be roughly $90; which is a fraction of the cost of repair or replacement of a stainless prop or the lower unit. The Piranha has the added benefit of allowing the repair to occur while on the water, which means we can continue with our search and rescue operation and not need to take another boat out of operation to come to our aid.
Overall, I was very impressed by the Piranha prop. It delivered what the manufacturer promised and is definitely worthy of your consideration. Admittedly, I wouldn’t use this prop if I were involved in a competition where performance was crucial, but for the rest of us that aren’t competing in our boats, this is a great prop, especially if you operate in an area where errant rocks and logs tend to seek out props.
