Good call! Why didnt I think of that!

Potential problem:

Lets say the boat/tranny/prop we have is standard.....what are the chances our donor motor is the opposite? We got the donor motor from a i/o cutty cabin boat.

Standard rotation. Look at the tab with the timing marks- BTDC is above the zero.

If the donor motor came from a sterndrive application it is a standard, counterclockwise rotation engine. GM Used to build right hand rotation engines but they are no longer available as production items. The advent of marine transmissions and sterndrives that can live up to full power in forward or reverse eliminated the need. We still build a few RH engines that are used for repowers in some older boats.
