    The owners manual says to replace the impeller each year at the dealer. I bought it new in 2000. I haven't done it yet. and the thing still pumps water after five years. So I guess my question is does it need replaced yearly,even if its running fine ,or only if it starts sputtering. Can I do this myself with little trouble.

    it no doubt tells ya to replace every 5 at the dealer so the dealer makes money. i have an '88 9.9 mariner/merc that i got used in 2000 and havent replaced it yet, still pumps water like a charm and ive used the h#@l out of it. as long as its pumping im not worrying about it.

    Guys to chime in here and to make a point. I would change the impeller every other season and the whole water pump every other time I changed the impeller.

    The life of that power head relies on it cooling. I have seen them come apart when you least expect them to and when it does and you are a good ways away from the ramp you are gonna over heat.
    Now let me ask you this. Does your 5 h/p have a warning system on it for over heating. If it doesn't then by the time it heats up the damage his done.
    A impeller change is a way lot cheaper then a power head.

    You can change the impeller your self and save the labor.

    Then since I haven't changed the water pump or impeller I need to do both this year. Should I let a dealer do the water pump. If its something else I can do. Can I get the Section on water pump and impeller replacement from a service manual in a download anywhere? Or should I just see If I can order one from merc? thanks for your assistance.

    Like mutt said you can do it it ain't no biggie. You can go down to your local library and check out a repair Manuel for it. Most libraries carry them or if you want me to I can pm you a link to where you can order one.


    I like the OEM Manuel's but the seloc will do just don't get the clymer.
