Bob, I tried to find the conversion tool on the Gates site, can you send me the link?

I 1) tightened the alternator belt and 2) sanded the alternator and motor pulley. The slapping seems to have gone away. Can't tell you which had the bigger impact but the combination worked. Thank you all for your advice.

Click the button for "find parts by application" and then choose "power units and marine engines."

Your Yanmar model should pop up at that point.

Here are my results, and again I chose the Heavy Duty (green stripe) model:
