Your Tohatsu’s propellers are responsible for keeping you moving, but what if they could also protect against lower unit damage? Lower unit damage is caused by the shock that happens when objects hit the propellers while they are running. Let’s explore your options for different propeller types to see why the Piranha propeller found in the Tohatsu Prop Finder is the best option to help with this issue.

Stainless steel propellers are known for their durability, and will have to be replaced less often. The high tensile strength of the steel allows for a thinner blade, which helps a little bit with shock absorption. Stainless steel propellers are not very flexible, however, so in the end the shock that is taken by your lower unit during a propeller strike is substantial. These are also the most expensive option.

Aluminum propellers are more flexible than stainless steel, and they cost a little less, too. They are the type used by most boat manufacturers, and the propellers that came on your boat when it was first made were probably aluminum. It is less durable, however, so it does take replacing a bit more often and get damaged a bit more easily.

Composite propellers are easily the most affordable currently available on the market, but they are often made of low durability materials and need to be replaced often. The possibilities involved when working with composite formulas are endless, though. Different composites can be vastly different based on how they are made and molded, so they do have some promise if you select the right propeller manufacturer.

In the end, none of these represent the be-all-end-all when trying to protect your lower unit. Lower cost, higher flexibility materials are best for this goal, but this also mean you will have to buy more and replace them more often. None of the three are actually manufactured with your lower unit’s protection in mind. But there is also a fourth option that leaves the other three in the dust.

Piranha propellers are made with a uniquely formulated composite that is more durable than stainless steel, but more affordable than most composites. It is flexible, but built to last, and its superior design is backed by a lifetime guarantee. Piranha propellers are modular, and their center hub contains a strong aluminum core. Each blade is removable, so that you do not have to replace your entire propeller in the event that a single blade becomes damaged. Your spare blades can be easily stored, and installing a replacement blade is fast and simple. In just minutes, you can be back out on the water, instead of waiting for an entire new propeller to be purchased and installed. Our blades are double the industry standard for balance, making them perfect for the job which they were designed to do. Unlike the other options, Piranha blades are specifically designed to protect your lower engine unit from damage. They will absorb the shock from a propeller strike, leaving the lower unit with little to no shock damage whatsoever.

Of the many important factors involved when choosing a replacement for your Tohatsu propeller, lower unit damage is the one most often overlooked. Lucky for you, the best choice in quality and affordability is also the only choice that is specially designed to protect your lower unit.
