Greetings, I'm shopping for a propeller for my 1993 Hunter 33.5, with a Yanmar 3GM30F and a Kanzaki KM3P. The issue I'm having is that everyone wants to know the gearbox ratio and I can't find it! For reasons unbeknown to me it's not stamped on the tag! Do any of you fellow 33.5 owners with a 3GM30 and a KM3P know what your ratio is?
Transmission ratio
- Thread starter Sutric
- Start date
That is my KM2P….
But I found this reference…2.36:1
But I don’t know how many other options were available.

I also see references to a 3.20:1. And a 2.61:1 gearing.
I wonder if you can put more light on the tag or clean it with something to try and make the gear ratio more visible?
Lastly, since you can make out the serial number, maybe a call or email to Yanmar / Kanzaki can confirm which gear ratio your tranny has.

There isn't much room, however, you might try a "gravestone rubbing" on the model number. There is a faint mark and it looks like a 2 at the end.
Or, contact Yanmar, see if they can help.
