NORMALLY, they are standard LH rotation with a single engine. That does not mean your 75 engine hasn't been changed.
Does it crank over? If it does, just look at it and see which way it's turning.
generally i don't think they put counter rotating engines in single engine boats. sometimes in twin engines setups. sometimes the engines rotate the normal direction and the change of direction takes place in the drive.
i think the normal direction is cw when viewed from the fore side of the engine.. looking at the balancer. looking aft in ft. of the engine.... if i'm wrong, i'm sure someone will set you and me straight...
