Re: Water Pump

This is a tough one to answer with a specific time. If you run in water that has a lot of debris, sand or trash that may damage your pump over time, you need to change it more frequently. In regular water, like most of us run in, it will last much longer [years]. I've seen pumps that were 20 years old and the impellers were still relatively flexible and the pump working good. Just changed one on a '83 Johnson like this. Most won't go this long, however. The main thing is to keep an eye on your temperature and water flow. Installing a pressure gauge would be the best approach to heading off trouble. Maybe some of the other guys will be more daring than me in giving a precise time.

Re: Water Pump

That's a good question that musters differing viewpoints depending on the hours your engine has on it between waterpump servicing and whether you boat in fresh,salt,or silty waters.I motor exclusively in salt water and replace my waterpump every two years with a complete kit and change the T/ststs with new assemblies every year to insure that they operate smoothly and have not developed any crusty resrictions.Haven't had a cooling issue to date.Monitoring waterflow from your engines tell/tale and exhaust reliefs occasionally during operation can keep you apprised of your waterpumps health.A pressure guage and or temp guage is also an added line of defense against a potential water cooling issue.<br /><br />Edit: Seems Jack and I think a little alike except he types quicker than I do. ;)
