Hi, 1st post, seems to be a wealth of info here. I'm thinking of buying a 96 proline with a 96 mariner 115. Don't know anything about newer outboards I do own a 1964 evenrude 40 that would'nt die if I wanted it to! 1st question, any known or common concerns and 2 boats been sitting 3 years but the guy has it running now What should I be concerned with?Plan on replacing the impellar, but anything I should watch for? Been a ford tech for 20 years, but not much on outboards
