Hi craigj, and welcome to iboats.
Glad to have you aboard.
Sorry I'm no Yamaha expert, but have a chart that may or may not help you.

Normally, you should post a yamaha question in the Yamaha forum:
http://forums.iboats.com/forumdisplay.php?s=&daysprune=&f=26
Or in the "outboard non repair forum" :
http://forums.iboats.com/forumdisplay.php?s=&daysprune=-1&f=16
But we'll cut you a bit of slack seeing as you're new here.
I'm sure you will get the hang of it as you post more questions.
If you don't get a definitive answer here, try posting on one of the 2 forums listed above.
