I owned a 1967 Excalibur 26 for a number of years up to about 20 years ago. A couple of thoughts: I found that the outboard in a well arrangement was very convenient, but the engine would sometimes stall out. The reason was that the outboard
exhaust would bubble up and the fumes would kill the engine. I solved this problem by running a tube from the
exhaust down further in the water, so the
exhaust would go into the water rather than the well. We also ran into some concern about the stability of the keel, at one point we found some motion in the keel and had to have it reinforced. Unfortunately i don't remember the details. Enjoy the boat.
