These polished steel propellers are designed to provide boaters an additional option between Painted Stainless 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 aggresive than the Painted Stainless Steel propellers, so pick a pitch size one inch lower. 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 aggresive. This 3 blade design is also available in left-hand rotation for twin-engine boats.
NOTE: It is generally best to pick the pitch of propeller that produces engine speeds near the maximum engine speed range shown in your Owner's Manual. 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. On-water propeller testing is always best.
