  • Tri County Properller offers PropSpeed and PropSpeed Application services, giving you more speed and burning less fuel. Propspeed is the original propeller and running gear foul-release coating system, specially formulated to prevent marine growth from bonding to metal surfaces below the waterline.

  • Dynamic balancing is computerized electronic balancing that ensures proper function of your propeller, which goes far beyond standard static balancing from a local “prop shop.” Our dynamic balancing station is powered by ProBal Dynamic Balancing software, and can determine if a propeller is balanced based on its rotation. Every propeller is dynamically balanced before being installed on your boat.

“It is so nice to deal with a company that delivers products and service on the time table that was promised. Couple that with the quality of workmanship that we received, on the reconditioned shafts and couplings, and I would rate your company far superior to any of the other Prop shops I have dealt with in South Florida.”
