I have a Tohatsu M8B 3B2 (8HP) 2003 2 stroke. I bought it used last fall and went though the basics. Lower unit was checked periodically and stayed fresh. I used it last week for a few hours and checked the Lower Unit oil today. It was milky, Boooo. So I am planning on doing the Lower Unit Gasket Set in the lower unit. What else should I do when I have it apart? I am also planning on doing the Water Pump Kit while i am in there. Does anyone have any other suggestions, advice or pitfalls I should watch out for? I love this motor because it runs fantastic. I want to get this done soon. Thanks for any input on this. I have never done it with this motor but it looks like it should be fairly straight forward after I get the kits. Love to hear from you.
Sincerely,

Dave

It's as easy as it looks. Just pick up a service manual before you start so you don't make it harder than it is.

Thanks for the input. How much are the manuals and where do you suggest is the best place to purchase the parts. Thanks.
