I've also heard everything is different on the engine parts/swap.... As for the hole in the case, I have 2 with the same problem. The hole is from a connecting rod that has come loose (usually from a rod bearing that went out). The rod snaps off, and when the crank shaft comes around, it blows the rod right through the top of the case....If you crank the engine over, you will see the rod end pop in and out of the hole you are seeing....You are going to need an engine, which is usually hard to find for a 700-S; How-ever, there are currently a couple on Ebay, and one is in Ohio (not far from where I live).
