standing in front of the engine looking towards the rear of the boat. CCW is reverse rotation (RH) CW is standard (LH).
The RH and LH designations come from standing behind the engine looking to the front of the boat.

If you turn a regular car engine backwards, the rear seal will leak oil like crazy.

It shouldn't matter which direction the engine rotates. You will have to index the trans pump. All this means is on the front of the trans, there is a plate that holds the front main seal. Well this plate can be turned 180 deg. It was the position of this front plate that controls the direction of the fluid flow. If the plate is not turned the trans will actually be in reverse while you are going forward. I learned this the hard way. The prop will have to be changed as well. Things can be changed to accomodate a standard rotation engine, just index and prop change!! -Brad-

There are some modifications that would need to be done to an automotive engine. There's a boat building website Glen-L.com that sells a book about marinizing engines.
