Believe it or not, that's not the first engine I've removed with a chainsaw. I bought another engine from a rotten houseboat a few years back and did the same thing. A cut through the stringers and floor in front and rear of the engine and a cut down the length of each stringer, and whoa-la...out the engine comes cradle and all. Makes it easy to strap down and haul away too since the engine's still bolted to something...
