Question for Rodbolt. I was reading about outboard motor oils, is one better than another. During the conversation you mentioned something about Suzuki had the 100 hour head removal as late as 95 or so. Was this part of the normal maintenance of the motor? Could you explain a little? Also what is decarbing? I think this is the word you used? Is this about carbon build up or a carburetor adjustment and cleaning situation? I really enjoy all the information. This is great. I could stay on this site for hours.<br /><br />ttp
