A Bad Prop Burns More Fuel, Causes a Loss in Power
and Can Damage the Motor


A n out of balance prop can cause severe vibration, premature wear on strut bearings, v-drive or transmission bearings and shaft alignment issues. It can also cause the shaft coupler bolts to break and you could loose a shaft!

The most important part of propeller repair is the shop that does your work. You can’t just go to any welding shop. Specialized equipment is required, and we have seen many occasions where an improperly repaired prop has caused severe vibration issues and loss of power. At Bismarck Prop Works we have all the necessary equipment to fix aluminum and stainless steel props. We are able to properly balance props so there is virtually no vibration. Using molds, we are able to ensure the proper shape is maintained. We understand how a propeller performs, the technology behind it and how to tune your prop for better performance based on your needs. We can also suggest different prop materials and designs based on how you use your boat.
