I have often thought about it. I'd love to have the space under the cockpit to make a big bed. However, my engine jsut shown far too much life to even consider it yet. J29s do it and they are quite similar to a J30 just about 1000# lighter. I think they use 7.5 HP outboards. I might use a 9.9.
However, redoing all of you fuel lines very carefully and cleaining the engine compartment might do well enough for you. I did that during a recent refit and my boat does not smell of diesel and she used to.
