If a complete overhaul is in order, I can tell you up front, you're not going to make any money on it. You'll easily put more into it than you're likely to get, even on eBay. Most folks who restore vintage motors do it for their own enjoyment, and VERY few make any money at it.


Seized up can mean any number of things - bad lower unit, rusted crankshaft & bearings, stuck pistons, or any combination of those. None would be cheap to fix and you'd be unlikely to recoup your investment.


Bottom line, unless you are looking for a learn-as-you-go project to tinker with in the basement this winter, let it go as is...
