I'm going to have to replace several parts on my engines.
How does one determine the rotation ?
Thanks

Go here and look at the starter page. It shows how to figure it out. http://www.arcomarine.com/

Welcome, what parts are you changing that require you know the rotation? A simple question about marine rotation can get confusing you can have a right hand rotation engine with a left hand outdrive.
I was going to explain it but it's easier to quote another site. This site is good info on any basic marine engine questions.

Since you usually cannot see the flywheel with the engine in the boat it can also be determined from the front of the engine. If you are looking at the front of the engine at the belts and pulleys, clockwise would be Left Hand, and counter-clockwise would be Right Hand. Never rely on propeller rotation to determine engine rotation. ALL I/O ENGINES ARE LEFT HAND!
Here's their website.
