Other engines will probably fit the engine mounts, because Yamaha makes them universal for many of their 2 stroke skis. The problem will be the exhaust system, and matching the drive shaft to the pump. In some cases a different engine might require an entirely different pump. I've seen several posts on other forums where guys have put 4 stroke engines into the 1300 hulls, and I suspect that might be possible on the XL1200, but you are talking about having to move all the electrics, etc., and the cost would be more than a good used ski.
Bottom line is that its possible, but usually not practical or worth the expense.
