Re: '54 evinrude 15hp - worth buying for $300?
Well, this is my last post on the topic.....

Condition means a lot to me. Here in the south, I can find VERY FEW 50's outboards that don't have bazillions of hours on them. This one appears to have very few. Prop and skeg condition are a biggie as well. Does it come with the dual line tank??? If all those conditions are satisfied, I'm willing to pay more than I would for the usual non-running, most likely "parts motors". This one looks like a keeper. I would want to check compression to verify in my feeble mind that it was a low hours motor or at least in likely good condition. I've also gotten to the point that I'm pretty sure I can feel connecting rod slop when I rotate the flywheel a little.
I seriously doubt this motor would run due to the almost positively cracked coils, so that wouldn't be a big deal to me. I'd also pull the plugs and look for milkiness on them because I don't like to pull the head on an oldie unless I have to. I wouldn't want this particular motor because it's a '54, but if it were a '55 or '56, I'd be willing to part with up to $250 for it.
It appears to be in really nice shape. The OP lives in Austin (long boating season), so I bet he won't find too many in this kind of shape that are for that price.
