What Jim is saying is that if the engine is in a car, it's a "right
hand" (Clockwise) engine.

If exactly the same engine is in a boat, then it is "left hand"
(Counterclockwise)

I think......

hand rotation not sure but is that not turning the wrong way? Help
would like to buy but not to sure if this is the correct motor for me
any suggestions?


Don't know if this helps:

http://www.boatpartsinfo.com/enginep...ngineRotation/

"Rotation is always determined by looking at the flywheel end of an inboard
engine. The flywheel of a standard rotation engine turns left, or
counter-clockwise, when viewed from the flywheel. The flywheel of a reverse
rotation engine turns right, or clockwise, when viewed from the flywheel.
Most single engine inboard and I/O boats use a standard rotation (L.H.)
counter-clockwise engine."

"Rotation with marine engines is always viewed from behind the engine
looking towards the flywheel. Standard rotation (left hand) means the
flywheel is turning counter clockwise looking at it from the rear, or
another way to think of it is that the harmonic balancer will turn clockwise
when standing in front of the engine looking at it."
