Piranha Propellers B Series 4 Bladed Pack Of 4 Blades 13 X 20 | 1320B-4

Piranha blades are designed to absorb the shock of a propeller strike, preventing damage to the lower unit, gears, and prop shaft. Each blade is made of a high-strength aerospace composite material that has been specially formulated. The center hub is made with an aluminum core that is overmolded with the same high-strength composite as the blades. Every Piranha blade includes HydroBites, which are precision ridges that improve hole shot, reduce vibration, and control ventilation during tight turns. The rear cap completes the propeller by holding the blades in place in the hub.

You’ve probably already heard it all before from your veteran boating buddies, the folks at the marina, and every magazine writer in the business, that “You should always carry a spare boat propeller.” That’s not bad advice at all. But if you use a Piranha prop, we’ve got BETTER advice:

“Always carry Spare Blades.”

Piranha’s boat propeller offers the fastest repair time around, but it’s important to have the parts to do the repair with. Whether you use 3 blade boat propellers or 4 blade boat propellers, since you can’t break more blades than are on the prop, we encourage you to simply carry a full spare set. True, you probably won’t damage them all at once, but this way you can ensure the propeller remains properly balanced and maintains the correct propeller pitch. Besides, won’t you feel better knowing you can fix it if you do, without ruining the rest of your day?
