This looks like a good engine at a good price, especially if it includes a fuel tank
hose and priming bulb. A good used one is hard to find at a bargain this time of year because fisherman use them for trolling motors and new ones are expensive. Someone should snap this up, it should be nearly as good as a new one.
Is there a manual?
It would be a good idea for the buyer to water
test it at full throttle under a load, check the gear oil
looks good, and confirm the age of the impeller. I change mine every year or two no matter how much use they see (Yamaha 150, 70, 9.9, 8.)
