I know this is the wrong mfgr forum, but the JohnnyRude guys have the answers. I have a Nissan (Tohatsu) 9.8HP 2 stroke that is about 10 years old that needs to be de-carbed. (Did my Johnson 110HP today). This is my trolling motor on a boat that can't go very fast on the Nissan. If I de-carb this motor, the procedure assumes that I am going to 'blow the carbon out" afterwards. I can't get the RPM's up very high (boat weighs 2400 pounds). Will running at lower RPM's under heavy load be sufficient to clean the carbon out? I had an '83 Evinrude 9.9 that I de-carbed and ran it at higher RPM (along with my boat being propelled by my 110 HP, and after that, I had effectively blown the crank out of it. Don't want to go that route again. Thanks for suggestions.
