Find A Boat Propeller From Piranha Propellers

There are three main factors to be considered when replacing your OMC propeller. The ideal propeller should be durable, be cost effective, and protect your lower unit. After taking a look at what is out there, it may seem impossible to find the best of all three factors in a single product. But the Piranha propeller is just that. Check it out at OMC Prop Finder.

The first factor that we will explore is durability. The least durable of all options currently on the market is the composite propeller. Most composite propellers are made with lower quality materials than metal propellers, and have to be replaced more often. The next step up is the Aluminum propeller, which is the choice used by most boat manufacturers for the original engine propellers. It is a bit more durable than composite. The most durable propeller type is thought by many to be the stainless steel propeller, but they do not know about the Piranha. Piranha propellers combine an aerospace composite coating over an aluminum core, and features blades made of the same special composite. This composite is individually formulated to be stronger and more durable than stainless steel, and to last longer as well. Taking into consideration the Piranha’s modular design and lifetime warranty, it is the clear winner for overall durability.

The next factor is affordability. Due to cost of manufacturing, the stainless steel propeller is the most expensive on the market. Aluminum is a lower cost metal than steel, and this is reflected in the lower cost of aluminum propellers. But keep in mind, their lower durability means you will have to buy new ones more often. The most affordable option is usually the composite propeller, but they are also often made with lower grade materials and will need to be replaced far more often than either of the metal options. The Piranha propeller’s special composite is both affordable and effective, it costs no more than most other composites, but also last longer than stainless steel and is the most cost effective. It also comes with a lifetime guarantee, meaning that the first full set of Piranha propellers you purchase could be the only set you will ever need to buy. Again, the Piranha propeller wins.

Lastly, let’s explore the very real problem of lower unit engine damage. When your propeller collides with any solid object that is in the water, the resulting shock can cause severe damage to your lower unit. Different materials and designs can help to absorb this shock so that your lower engine does not take as much damage. Stainless steel propellers are made from a strong and durable material, which is good, right? Not when considering the need for shock absorption. Aluminum is slightly more flexible, and therefore slightly better at protecting you lower unit. But aluminum is still not the best option for this issue. Composites are more flexible than the two metal options, and by default are better and shock absorption. But most composite propellers are not actually designed with lower unit protection in mind. Piranha propellers are, and are specially molded and calibrated to ensure the best shock absorption possible, which all but eliminates any damage to the lower unit that can be caused by propeller strikes.

In all three areas, Piranha propellers are the clear choice. Visit the OMC Prop Finder to find the right model for you.
