I have a Yanmar 3QM30F engine
I have a Yanmar 3QM30F engine on my sailboat. Forward gear is slipping. The transmission is ratio 2.03. Have been offered a ratio 3.01 transmission but was told the engine was not powerful enough for the 3.01 transmission. What am I missing here? Seems to me that the propeller will now go about 50% faster for the same revs as the 2.03 ratio transmission. Am I right or what? Will the 3.01 ratio be faster or slower?
