Might be the best running 2 stroke engine ever made. I don’t think a 1970 model had the shock absorber. Universal mag. It might run as is, might need points cleaned or might even need coils….it all depends on what was in there to start with and how long it was there. The thermostat (if somebody left it in there, I hope) is good for idle speed stability. I’d a least put it in boiling water to make sure it opens and closes. A new one would be best but they are costing up towards $50 in some cases, these days. Lower crank shaft seal system has the spring and cross pin arrangement. You have to turn the drive shaft as the lower unit is dropped to change the impeller, or you will bend a small roll pin on the drive shaft. You technically don’t have to pull the power head to change the impeller anymore; but if you do pull the power head, you can be much more assured that the lower crank shaft seal is in good shape and not damaged. Make sure you tell the new owner to be very careful of the shift handle. Do NOT lay the motor on that handle! It is very fragile.
I would agree, this engine was one of the best running, most durable, easy to service outboards ever produced by any manufacturer. Yeah, they are good trolling motors, not much for WOT power though. Listen to Bill’s advice about pulling the powerhead to check the lower seal components, and no stupid driveshaft shock absorber on these engines. And yes, be very careful with that shift handle, easily broken, and expensive to replace.
