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?
