Just wanted to thank those who gave detailed info on how to perform the job of replacing the water pump on my 115 Yammy. First time to crack open the lower is a bit unnerving - went real smooth though. I don't know whether it was the new water pump or simultaneously adjusting the pilots to 5/8 ... but this motor idles and runs like a top now. Bump started all day long like a motor of two years ago. Love it! Thanks again for the help - Spete
