These polished steel propellers are designed to provide boaters an additional option between Standard Black Steel Series and more expensive Pro and Saltwater Series propellers. A number of specialty boats will perform better with these specialized propellers. These propellers are generally more aggressive than the Standard Black propellers, so pick a pitch size one inch lower than the standard propeller. If a Pro or Saltwater Series prop was used previously, pick a pitch one inch higher when trying one of these propellers because they are slightly less aggressive. This 3 blade design is also available in left-hand rotation for twin-engine boats.
NOTE: Speed ranges vary for different models because of different engine operating ranges and different gear ratios. It is generally best to pick the lowest pitch propeller that produces engine speeds near the maximum engine speed ranges shown in your Owner's Manual. The propeller speed ranges shown are only a guide. More accurate information for a particular boat may often be obtained from the boat manufacturer directly or by visiting the Yamaha web site at www.yamaha-motor.com and checking out the Performance Bulletin section. The best way to select the best propeller for a particular boat and customer is by testing various propellers on the boat.
