Sierra's 18-3470 is a water pump repair kit for late model four-stroke Yamaha engines of 225-350 HP. It stands in for Yamaha part 6CE-W0078-00-00. The kit holds the wearing parts, among them an impeller and an outer wear plate, along with gaskets and seals. The pump housing is not part of it, so the housing has to come from your existing pump.
Our take
With the housing left out, the 18-3470 supplies the impeller, wear plate and seals but not the pump body, so the housing has to come from your existing pump. It is stated for late model four-stroke Yamaha 225-350 HP engines.
