Ok, I have an 2003 90 hp yamaha 2 stroke. Motor has been great and been through hell. 90% saltwater running.. but lately has only been in fresh. I took it out this weekend and it ran well. but not as smooth as normal. A little slower out of the hole and idles a little rough. I did put different oil, that i have never tried in in this time but, I believe its time for a tune up. I have replaced the plugs a couple years back along with the lower unit oil. i went to change the lower unit oil the other day and when a little drained out, it was still very new looking oil, so i left it in there. I am sure the water pump need to be replaced. or at least the impeller. I did notice that the water coming out of the engine was a bit hot... was it hotter than normal??? I havnt really noticed the temp before. Do yall have anyother susgestion on what to replace while doing this maintance. Should I get the shop manuel or the tune up and repair one. There appears to be multiple manuels for the same engines. Which one do I need, which one has instructions?
Thanks,,
Will
