I don't have any personal experience with the Penn Yan tunnel drives but I
do live close to where they were produced in the Fingerlakes of NY and see a
lot of them in the local marinas. I also own small PY outboard runabout.

As far as I know, Penn Yan offered tunnel drives on a number of different
boat models so keep that in mind when considering people's experience with
ride, fuel economy etc. Size hull and motor may have a larger bearing on
performance that the drive type. The company made very nice wooden boats
for years and switched to fiberglass in the 70's. The fiberglass boats tend
to be more utility/fishing design without a lot of frills. The Tunnel
drives do very well in the shallow areas for which they were designed. I've
heard that slow speed handling (maneuvering at the dock) is a little tricky
compared to a stern drive.

Good luck,
