Yamaha 25hp Motors – 3 Blade / 10 Spline Shaft High-Thrust Aluminium Propeller ** Yamaha’s large-diameter, low-pitch dual-thrust propellers are designed to give instant power in both forward and reverse, by redirecting exhaust gases away from the propeller, reducing reverse ventilation and generating more power to the water. This increases forward thrust by up to 60% and reverse thrust by up to 70%
