How to Choose Propeller for Boat

• Check the RPM range recommended by manufacture listed in owner's manual
• Check the max RPM range by reading instrument panel to determine the optimal pitch and speed.
• If max RPM exceeds the recommended range, please lower RPM with one upper level pitch propeller.
  Keep doing this to get the appropriate propeller with the right pitch.
• If RPM is lower than the recommended range, please turn up RPM with one lower level pitch propeller.
  Keep trying to do this until you can find the right propeller.

1. Propeller adding approx. 3/4 pitch effect will better grip on water!
   
2. The best balanced wings without vibration
   Slender wings for high-speed leisure boat
   Thick wings for fishing-boat maneuvering in the waves
3. Mercury Accessory Propeller
   Interchangeable hub system for a motor higher than 60HP
   Rubber Cushion hub system for a motor lower than 60HP
4. Minimizing speed loss and prohibiting corrosion with high-quality coating
5. Surged hub : decreasing the tail pressure and preventing the exhaust-gas from approaching to tail wings.
6. A thin and sharp edge eliminates the resistance against water.

Propeller for Outboard Motor

Usage : Leisure, Military and Police Petrol, Small Fish Boat Material : Special aluminum alloy	Usage : Propeller parts Material : Combination of brass and natural synthetic rubber

BIM Propeller with our most advanced design system never allows any vibration under all conditions.

Cavitaion is caused by water bubble resulting from intense pressure decrease on the back side of wings. Cavitation results in mechanical damage, that is bended wings or damaged wings followed by improper selection of propeller according to power variation or impaired propeller design.
