Product Details
✓FITMENT - For select Yamaha 2-stroke 60-70HP (60, 60F, C60, E60, P60, 70, 70B, C70, 70ETLH) and 4-stroke high-thrust 50-60HP (T50, FT50, T60, FT60) lower units on the 6H3 pump. Match the model code and old housing stamp.
✓REPLACES - Replaces Yamaha 6H3-W0078-02-00, superseding 6H3-W0078-01-00, 6H3-W0078-00-00 and 6H3-W0078-A0-00. Quicksilver 8M6012797 is the cross-brand number. Crosses Sierra 18-3461, 18-3466. Not genuine Yamaha.
✓BUILD - One kit: neoprene impeller 6H3-44352-00, nylon PA66 housing 6H3-44311-00, insert cup 663-44322-00, wear plate 6H3-44323-00, 3 gaskets, O-ring 93210-46044, woodruff key 90280-03M03, 4 bolts with washers. Gear lube not included.
✓FUNCTION - The impeller lifts raw water through the lower unit to the powerhead. Replace it for a weak or absent tell-tale stream, an overheat alarm, melted impeller pieces, and water in the gearcase from a failed pump seal.
✓BEFORE ORDERING - With-housing kit only, not the housing-less Sierra 18-3465 or Quicksilver 8M6012798. Yamaha used more than one pump in this range, so match the model code and old housing stamp.
