My supply of parts for the Wilcox Crittenden headmate on 2003 hull #218 are exhausted so I decided to install a PH powerflush head. Has anyone done this on a 310? According to the manual I need a #6 wire based on the approx. 25' (one way) run from the breaker panel down to the aft berth, up through the rigging tube and across to the head. Wondering about the best way to step down from a #6 wire to the approx 16 AWG 12" pigtail wire on the head motor and connect #6 to the 20 amp breaker? My plan is to route the outlet from the reefer/shower sump wye valve to the existing head intake, and move the head intake to a tee in the sink drain per Peggie's book. If you have teed into the sink drain and have some photo to share I would be interested. Thanks
