I have inherited a dusty 3hp Evinrude, model # 3706C, serial number E08268. I don't know how old it is. It hasn't been used for three years and has been stored with gas in the tank in the garage during that time.<br />I'm about to dust it off and go on vacation. Before I clamp the outboard onto the dinghy, what should I do to prepare the vintage engine for use?<br />What about oil-fuel mixture?<br />Any tips or suggestions would be appreciated!
