What About Read the Manual?
Some may think that's un-American, or, as my wife says, un-male.However, all the information you need is there. If you don't have a manual it may be available on-line or as a "part".The people that make these things should have a good handle on what should be done as they know their products intimately. At least my old '93 Johnson 8-horse Owners Manual is pretty good. It's amazing how some products have little idiosyncrasies and missing something could be costly.Anyway, that's my 2-cents worth and that's what I'd do. (p.s. for this board there's no charge!)
