Picked up Yamaha part 682-W0078-01-00 (WATER PUMP REPAIR KIT) from Boats.net.
Planning to replace the impeller(#21) and surrounding gaskets and seals. The kit included the parts below.
UPDATE: Replacement was not too difficult, loosening the nut which connected to the shifting mechanism was the most difficult aspect. After taking the lower unit off, all of the parts below were replaced. This project was done because its something you should do every few years, but also water was not being pumped through the engine and therefore not cooling the engine properly.
Unfortunately, it looks like there may be a problem somewhere in the head unit, so further investigation is now required.
