I hate to tell ya the bad news bud but ole ZOOK is exactly right. While I got your ears ifn you would like to upgrade to a 1987 motor of 115hp same motor just newer I have one that I am just about giving away. If you decide to rebuild yours I have several places that can really help you out as far as prices. PM if you need any more info.
