That's why I specified looking at the prop from stern to bow. I do live in The Colonies where we use that convention.
I did manage to lose a left hand prop one time. Going in reverse the prop hit a rock and unscrewed itself, despite having a tight locknut behind it. This was in less than a foot of water, and an hour's searching never found it. It was a Prop Shop prop, too, so not cheap to replace.
Ttony, back to your original question: LH or RH makes little difference going ahead, but if you are going to be reversing often, as in navigation or towing events, you want to consider "prop walk." That's the phenomenom that makes the stern kick to one side when the motor is in reverse. A LH prop (viewed from the stern) will tend to kick the stern to starboard, making docking on the starboard side easier.
