    How often should a person replace the water pump? I have had my boat 4 years now and never put a water pump on it. One guy i talked to said change it when it stops working. He said it has a sensor that will shut the motor off before it runs it hot enough to hurt anything. How often should they be changed?

    If you have an I/O as I do, change the impeller every 2 years weather it needs it or not. I learned the hard way. Lucky my boat didn't get too hot.

    Oh yeah, it's got a sensor all right that'll shut it done. Called a "BLOWN" engine.

    The guy that told you that, is he a backwoods inbread fool or what? Nobody I know will agree to that statement he made.

    In a saltwater environment, we recommend a yearly change, and not to exceed 2 years. In freash water and no sand from running shallows, you can exceed that, but not by much.

    I was wondering the same thing Paul or maybe a salsemen at a dealer lol.
    I change my impeller every year period I change the pump its self every 2 years I figure 40 bucks every other year for a impellor is a lot cheaper then 25k for a new motor and the pump runs me around 100 real cheap insurance I also change my lower unit oil twice a year.

    Who in the hell is selling you motors for 25 thousand dollars?!?!

    I change my impeller every year and water pump kit every other year. The whole idea is to change it before it's necessary.

    That's as complete as Sierra makes it for that year. Everything but the pump housing.

    Get it and do it.

    That kit will be all you need.

    There's just a drive shaft seal at the power head and under the water pump. You won't have to mess with either one of them.

    Tell your former "advisor" goodbye.The new motors have lots of sensors on them that will keep you from totally destroying a motor "hopefully" but it doesn't take much operation with no cooling water to fry an engine.Conventional wisdom that I have read recommends every two years UNLESS you operate in particularly sandy,muddy situations.There is a very good article in the latest Trailer Boats magazine about maintaining 4 cylces but much of it also pertain to 2 cycles also.Just remember it is called PREVENTATIVE MAINT.Would you run your car and not change oil until the warning light came on?:crazy: :big_smile: :smile2:

    Well engine oil if different it breaks down after so many miles. How many of you change your water pump on you car because it might go bad? You dont you just wait for it to go bad then change it. :lol: But i do understand what you are saying and with the sand and stuff that gets in there I'm sure every 2 years it would be a good idea to put a new one on there.

    Automotive water pumps don't have rubber impellors, and don't take the abuse of outboard pumps.

    Wow, you guys are sure breaking my bubble. I had a Mariner for 10 years and only replaced the plugs a few times never the pump. I now have a new Mec. 115 4 cycle and I figured I would never have to touch it in my life time except for the oil. Every two years for a pump:smile2: ?
