I'm looking at an ad for another vintage outboard where the seller's selling it as a "parts outboard" because he claims that it has a few problems and doesn't know anything about it, selling it "as is". The only thing that might be a big deal is that he says it doesn't shift, it's stuck in F now and the shifter isn't attached to anything (so he says). I havent seen this outboard yet so sight unseen, what might I be looking at IF I buy it? Any ideas whatsover?
