Re: fuel oil ratio chrysler 9.9hp outboard model 95h3j
The older outboard oils before TCW3 were not designed very well.The original outboard oil was actually designed to burn and carbon the cylinders and rings.
It took till TCW3 till they got it right.
Use any oil you want.
Amsoil is without a doupt the best also the most expensive.
I use it on other peoples stuff!!
You should de-carb with Seafoam or Power Tune at least once a year.
PM should be done all the time with an outboard.
I've seen people use a spray bottle with water in it to help remove carbon from the cylinders.(dont think I would).
boats . net worst place to buy parts.
Get towing insurance.Great investment.
