Yamaha - Water Pump Repair Kit - F225, F250, F300, VF200, VF250 - 6CE-W0078-02-00 

Ask any Yamaha tech and they’ll tell you the same thing—take care of the water pump before it gives you trouble. The Yamaha 6CE-W0078-02-00 Water Pump Repair Kit is one of those maintenance parts that keeps your cooling system working the way it should. When the impeller and seals start to wear, water flow drops and engine temperatures climb faster than most people expect.

This kit is typically installed during scheduled service or anytime the lower unit is already off the motor. It’s a straightforward way to refresh the cooling system and keep big Yamaha four-strokes running strong. For boaters who spend long days offshore or running hard, staying ahead of water pump wear is just part of good engine care.
