NOTE:  If using Uncupped Propeller, use Cupped Propeller with 2" less pitch. Boats with power trim may use same pitch.

QRJ-T 4-blade  gives better holeshot, less torque on steering, better boat handling and lower planing speeds.

REVERSE HOOK CUP PROPELLERS

Propco's patented Reverse Hook Cup Propellers are designed for use on houseboats, workboats and barges. 'RHC' technology gives up to 200% more reversibility - allowing drivers to turn more effectively, stop forward momentum, and control the boat while in reverse. Customers have stated the RHC propeller literally "takes the fear out of returning to the marina" and with this prop "the stern will now swing around and hold into the wind".
