Well, the good news is that this later version of the 10hp powerhead has the larger wrist pins with needle bearings, so chances are good that the powerhead is serviceable. Needless to say, you would want to check the compression, although all the oil in the cylinders may give false high readings…The other good news is that it looks as though the gearcase has been replaced at some time though. Like others have said, you would definitely want to drain the gear lube, count on rebuilding/replacing the gearcase if you find it to be full of water. Good driveshafts for these engines are tough to find and the frozen shift lever is not a good sign.
The bad news is that this looks to be a salt water motor, so even the simplest of repairs might involve torch assistance.
All that being said, this would be the perfect size engine for you 12′ tinny though. So, I am in agreement with everyone, offer considerably less unless you confirm that gearlube is free of water and compression is good. And, be prepared for this to be a “parts motor”.
I’m thinking you will find a better candidate for purchase at an AOMCI meet this winter. But, there is surely nothing to lose by having a look at this one if you don’t mind the drive.

The powerheads got better, but the lower units are not near as good as the older 5 bolt.
