[C320-list] Engine Reduction

[Karl Mielenhausen _/)]

Doug,

As Dick mentions, the only sure way is to verify on your own boat. You  
should also have a "Material and Equipment Log" as one of the last pages  
of your owners manual. That would state your engine info and gear ratio.
Given your hull number, I suspect you have the Japanese Yanmar with the  
2.21:1 transmission ratio.
