Propeller Services

We have two complete propeller service-centers and distribution facilities to help us support all of our customers' needs.

We provide technical analysis in identifying the most efficient way to maximize vessel performance. Using your vessel and engine specs, we'll show you exactly which propellers will help you with important performance issues.

The correct propeller sizeallows the motor to achievemaximum RPM withinthe manufacturer's maximum rated RPM range at wide open throttle. If you are below the rated RPM range you need to purchase a propeller with less pitch. If you are over the maximum range you need to purchase a propeller with more pitch. One inch of pitch equals approximately 200 RPM on outboard and sterndrive applications.Inboard applications depend on reduction gear ratios and operating conditions.
