This top-of-the-line propeller is specifically designed for single-engine, high-speed boats such as bass boats that require "bow lift" and a high engine-mounting height. The Pro Series™ propeller blades are designed with high rake angles, progressive pitch and aggressive cupping for excellent mid-range and top-end performance. The exhaust tube includes specially designed relief holes to improve low-speed acceleration. Available in three pitch sizes for the 70hp-130hp range and four pitch sizes for 150hp-225hp V6 Yamaha outboards.
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 full-throttle operating range 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.
