    looking to see what I need to do now that I have 100 hours on the ol out board. I was thinking lower unit oil and impeller? I'm still getting around 15psi water pressure but its cheap and worth doing.

    IF you have questions like that? Than i would spend the money to get the pro's to do it. I just did mine and thought that i could do it also but i'll have the pro's do the first one and then i'll learn how to do it after that. I just had my yammie 70's 100 hr service and new water pump installed.

    Start at the tank, follow the fuel line(s) all the way to the fuel pump(s).
    See how many filters there are. May only be two, one in the separater canister
    and the other, last chance filter, under the cowling.

    You will see it in a semi clear white housing. There should be one screw holding the housing to it's mount. The housing unscrews and It's just a screen inside. Very easy to do and it will run around $25 for the screen. Boats.net has the schematics if you need them. You don't need to take your engine to a shop unless you are still under warranty.

    Yeah, I think I can handle all future 100hr service for my boat. I'm no longer gonna give 300 bucks away to a shop for an hour's worth of work if that.
