That is VERY interesting. I do have a question.................why do you see single engine boats in reverse rotation? (I always figured it was "left over" stock from twins that didn't get built)
And in some applications the engine turned standard rotation but power was taken off the front of the crank to get the propeller to turn counter clockwise, these were mostly old flathead inline 6 and 8 cyl engines. Chris Craft also used this type of drive set up in the 60's and 70's using a standard rotation small block chevy engine, the transmission was bolted to a special timing cover and was driven off the front of the engine.
The whole marine engine reverse rotation thing must have something to do with the propeller but I still haven't found out why.
