PowerTech OSN4 Blade Propellers for 50-130hp Yamaha Outboards.
OSN4 - Yamaha Outboard Propellers are 14 inch diameter available in 1 inch pitch increments from 15-21 with right hand rotation. The OSN has a swept blade design with a narrow tip. It is an OEM equivalent for the newer style OMC SST. It is available in 3 or 4 blades. The 4-blade version typically provides better overall performance including: lift, hole-shot, handling, and overall grip. The Powertech OSN comes with a factory pressed in YM90 rubber hub bushing or the optional CLY135 Cushion Lok Driver.
The PowerTech Cushion Lok hub system provides smoother and quieter shift engagement and is far less prone to failure than standard rubber hubs. They are field replaceable for quick repairs or interchangeable between different motor manufactures.
