Got a guy that has three boats with two motors that were abandoned on a freind of his property. The boats are no good but I am interested in the motors...Evinrude 40 and a Johnson 70 they are free for the taking and he says they have no paperwork on any of the stuff...as far as I know paperwork is not needed for a motor...I am just wanting something to tinker on in my spare time. My question is the paperwork, enlighten me on this a little.
