Dean, I have a 2003 Yamaha 150 2 stroke. It still has the original water pump. I have heard others say they should be done every 3 years or so. I hate to fix something that is not broken, but I will get it done if you recommend to do so. If so, is February a good time? Thanks, Mike

water pump

Thanks Chris. I have the Seloc Yamaha repair manual, but it looked a little more involved than I could probably tackle. Mike

Water pump should be changed every three years at a minimum. I have mine done yearly because of the shallow water that I have to run the boat through.

Sorry for the slow response! I am not always on the internet, if I dont respond please always feel free to call or email me. Changing your Water pump and thermostats is really important to the life of your engine. The Yamaha engines use a wood-driff style key on the impeller and can be a real bear to get out with age. I like to perform water pump and thermostat replacements in the 175 to 225 hr mark on Yamaha product. Obviously if you run aground or have limited water to the pump in some way you should replace it sooner. Usually the two to three season mark is about right. Make sure you always replace the housing along with thermostats and poppet valve to insure trouble free use.
