Its the end of summer now where you are and I'll also bet the weather
is pretty good but I'll bet its not so nice in a few weeks.
What I'm getting at is that you've most likely missed this sailing season (does get pretty cold, right?) by the time you get everything worked out.
On the boat its old, petrol engine
does have a few "goodies".
I had a look on Kijiji and in what looks like your area there were a couple of similar boats on trailers.
With a shortish sailing season being able to bring the boat home for maintenance
must be a big advantage.
I'd look for a small outboard
in that size boat, rather than an old inboard.
