My first boat was a '78 19ft Olympic soft top, that after redoing the stringers/foam/transom, was planning on owning forever as it was a great boat(had it for 15 yrs). If you can't/don't want to do the work yourself, the bill can be staggering. Anyway, a 23ft Proline came my way with an offer I couldn't refuse, so had to sell the Olympic. I was asking $5500 or so with a healthy Yamaha 130 2 stroke/nice trailer, but ended up selling in October for $3800(as AP pointed out...it's the season). The boat was a sleek tank, and while I got wet a few times, never worried about making it home and I consider that hull to be somewhere in the top 10 best for our conditions. On the outboard hulls with the step down transom, the factory for some reason thought that putting an aluminum cap over the raw plywood transom was a good idea. If you see an Olympic that's still got the cap, you can assume theres at least some water in there, if not totally wet. A good sign is water weeping out of drain/transducer screws when boat is dry. We lived with ours being wet for years before the bowing with bigger motor made me nervous.
I've never been a fan of the hardtops as Olympic made them too short so you can't stand up on a bad day.....that said there's a solid 19ft Hardtop that was originally an inboard with that desireable full height transom/offshore bracket/05 Honda 130 4 stroke/etc in my neighborhood for $6000/obo and I see that in the motor/tandem trailer.
Sellers # is 360-853-6637. Good luck in your quest. Tom
