GHmarine Boat Engine Parts for Yamaha Outboard 61A-W0078 Editorial Review

The GHmarine 61AW0078 Water Pump Impeller Kit for Yamaha Outboard Marine 150 175 200 225 250 300 HP Motors 61A-W0078-A2-00 is designed to work with Yamaha outboard motors. While the product is of good quality, customers have had mixed experiences with it. Some have found that the gaskets don't line up correctly, and the water pump housing is machined incorrectly, causing the pins and gaskets not to work together nicely. The recessed tab is too narrow, and the woodruff key is visibly thicker than the original, requiring aggressive filing for it to fit. These issues have caused some customers to waste time assembling the kit. However, other customers have had no problems with the product, and have found it to be a great purchase.
