The Difference between Stainless Steel Boat Propellers and Piranha Composite Propellers

Stainless steel boat propellers such as PowerTech are among the fastest and strongest propellers on the market. These stainless steel propellers have been manufactured for over 34 years as a durable and secure propeller option.

Piranha composite propellers are made in California and are a hybrid combination of strength and performance, making them an all-round, reliable propeller that has been honored with the title of “best of props tested” by numerous magazines. Although not as strong or fast as a stainless steel propeller, they are a well-rounded option that is easily replaceable and very affordable.

Canada Propeller, a North American boat propeller specialist company that has been in business for over 20 years carries both the PowerTech Stainless boat propellers and the Piranha propellers because each propeller has its own distinct set of advantages.

Stainless Steel Propellers

PowerTech propellers have been widely manufactured and distributed since the 1980s which has allowed them to grow and evolve with the boat propeller industry. Unsurpassed in their quality, each PowerTech propeller is heavily invested in during the post-production effort to ensure leading edges are sharpened, the entire prop is detailed for material flaws, that blade height tolerances are verified, and that they are hand balanced.

PowerTech stainless boat propellers are proven to be the fastest boat propellers, allowing for maximum performance. Because PowerTech stainless propellers are also the strongest of all boat propellers, they do not require as much material, which means their blades can be thinner, allowing for the prop to turn easily within the water. All unused horsepower is then applied to better performance shapes and heavier cupping.

The strength of stainless steel blades on PowerTech propellers also means that they can easily cut underwater objects without damage and provide boat operators with more safety as well as peace of mind.

Piranha Composite Boat Propellers

Piranha composite boat propellers were designed as an alternative to expensive stainless steel propellers and weak aluminum propellers. Piranha propellers are made of an aluminum hub and advanced resin, nylon, and long-strand glass fiber. This composite ensures that the blades will not corrode or blister. If anything does happen, the Piranha Propellers come with a lifetime hub warranty, quick repair and re-pitch, and a factory direct blade exchange program.

Unlike stainless steel blades, Piranha propellers cannot always cut through underwater objects, however many times the blades will absorb a hit, eliminating lower unit damage. Even if a blade breaks, it is easy to replace within minutes and replacing three blades is still cheaper than replacing a complete stainless steel prop. This means customers no longer have to constantly visit expensive propeller shops and can repair damaged blades on their own, even while out on the water.

Piranha Propellers are manufactured to fit all the major manufacturers of outboard and sterndrive engines from 9.9HP to 280 HP, ranging in years from 1972 to 2020. To find the right Piranha Propeller for your engine, use our Piranha Prop Finder, or contact one of our experts at 1-866-621-7767.
