Welcome to Black Dog Propellers
We, at Black Dog Propellers, are experts in propeller repairs and sizing new propellers for repowers and new builds. We also sell new propellers and distribute for all major manufacturers. We utilize the Prop Scan® propeller inspection system for all of our propeller repairs and verifying new propeller accuracy. Prop Scan® allows us to perform repairs that adhere to ISO 484/2 tolerances on pitch standards, which makes our propellers extremely accurate. This accuracy will increase the efficiency of the propeller(s) and produce better speeds, reduce fuel consumption and eliminate propeller induced vibration.
We guarantee that your propeller(s) repair will be accurate the first time, whether we are adjusting for WOT¹ (wide open throttle) RPM, mismatched engine RPM or a performance tune up.
We guarantee our accuracy and our work!
Prop Scan® Overview Prop Scan® is used to optimize marine propellers, reduce fuel consumption, increase top speed and cruising speed, eliminate propeller vibration and match engine loading requirements. The computerized Prop Scan® was specifically designed to inspect the accuracy and precise hydrodynamic form of Australian, Canadian and US Navy propellers. The accuracy and form or shape of a propeller blade section as it slices through the water determines the ultimate thrust and performance of any vessel. Using Prop Scan® technology a Technician will measure your propeller free of charge, check the accuracy against the ISO 484 International Standards and determine the section form of your propeller. To optimize your propeller your Prop Scan® Technician can then correct any accuracy problems, apply the correct section form and also tune the pitch of your propellers. An accurate Prop Scan® propeller with the correct section form and pitch will always out-perform a standard propeller. You will get fuel savings, increased boat speed, reduced vibration, correct engine RPM and correct engine loading. For more information on ISO 484 tolerances and Prop Scan® click the links below:
