PowerTech SRT4 Stainless Propeller Mercury 6-20 hp
PowerTech! SRT4 Stainless Propellers for 6-20 HP Mercury Outboards.
SRT 4 Blade Propeller is 9.50” diameter, available in pitches from 8 thru 13”, right hand rotation and moderate rake. With more blade surface area than the SWA-blade style, it’s more suited to higher horsepower applications such as the new 15-20-horsepower 2 and 4-stroke Mercury motors. The 4-blade configuration provides more maneuverability (especially in reverse), improved fuel economy, and smoother overall operation.
The Powertech SRT 4 Blade comes with a factory pressed in rubber hub bushing for mounting using your original OEM Mercury Propeller hardware.
