[C320-list] Transmission oil change

[Daryl Hunt]

I'm about to change the transmission gear oil on my Yanmar 3GM30F 
(Japan) diesel.  I changed the crankcase oil before haulout last fall 
with Shell Rotella T 15W40.  The Yanmar Operators Manual says to use the 
same oil for the gear case as the crankcase.  However, my PO left a 
quart of CD 30 oil labeled "For Transmission" and a Yanmar (Japan) 
manual "Maintenance of Pleasureboat Diesel Engine - GM Series" aboard 
specifies CD 10W15 for engine and CD 30 for gear oil.  Since Believe's 
engine is the Japan version, I'm leaning toward the CD 30 oil.   Make sense?
