This is the genuine Yamaha water pump repair kit 61A-W0078-A4-00 for Yamaha outboards. It supersedes 61A-W0078-A3-00 and is cross-referenced to Sierra 18-3396-1 and Mallory 9-48618. The kit holds a cartridge insert, gasket, impeller, cartridge outer plate, 4 bolts with washers, a Woodruff key, O-rings and 2 dowel pins. Coverage includes 150 hp engines from 1997 to 2014 and 250 hp engines from 1997 to 2005.
Our take
The kit bundles the impeller with the cartridge insert, outer plate, gasket, O-rings, bolts and dowel pins, so the rebuild parts come in one box. Coverage on 250 hp engines is 1997 to 2005 only, so check your year.
