I don't know if this would work out to be a good deal or not. Certainly not for someone of my skill level. But, if you had a partially good engine, and the skills to do a rebuild...
I don't know. For $280 shipped you could have an engine to work on over the winter without having to park the Q for the winter.
Perhaps the cost of replacement parts and the labor of the rebuild would exceed the value. Might be cheaper to buy a used engine that is already in good shape.
