Have 1, new complete replacement motor (12V) for the Jabsco quiet flush head. This motor & pump assembly kit comes all together with the motor, seal housing with sealing o-ring, centrifugal impeller, macerator housing, and chopper plate with lock nut. Kit P/N 37072-0092. This kit that makes it a quick and easy replacement of the complete unit bolting to the matching part on the base of the head with 4 bolts. Just change this out quickly and save the tedious re-build for when you have the time; cause as we all know, the head never goes out at a convenient time. This is brand new. Defender sells for $173; I will ask $125 for this one
