I am wanting to purchase a boat and everything looks pretty good
except the outboard. The owner claims he has never had it in salt
water, but it has been in a freshwater slip for at least a year. Take
a look at the picture posted he

My questions a
- Is this normal for freshwater?
- If this is professionaly repainted will there be a good chance it
will look good again?
- What might that cost?

The stainless prop is a major contributor to this corrosion problem. There
should have been additional anodes installed beyond what Volvo provided. The
anodes used should be aluminum alloy or magnesium. Not zinc. Anodes Should
be replaced when 1/2 worn. If shore power is used, a galvanic isolator is
needed to prevent electrolytic corrosion.
Since the corrosion is not isolated to one component, I suspect there is a
problem with the bonding between the engine and transom plate. I do see some
bonding wires on some of the underwater components.
A proper paint job will add further protection once the cause of the problem
is corrected.

My judgment would be that this boat is worth $3000 (or more) less than the
equivalent boat without the galvanic corrosion problem.
