yamaha 90hp 100hour?
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.

I agree I just picked up the boat and Kinda want to do all of it at once so I know what shape everything is in.

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.

Well i have done 5 or 6 water pumps and worked a bit on out boards.I just wanted to know what he was talking about only filter i know of is fuel and the one in the tank
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.
