[C38] question for Yanmar owners

[Max Soto]

For all of you guys with yanmar engines on a C38,  what is the right
transmission ratio our boats???

There is a three cylinder yanmar for sale here, a 27 hp that was replaced on
a cat for an outboard engine. Not sure if it is a 3GM30 or a 3YM30, but I'm
checking that out tomorrow, so, that's why I wanted to check if the ratio is
ok for our boats.

Regards,
