Thanks fcd,
Thanks Bill,
I have some beginning of answers from Macboring which Yanmar seems to use for its customer service in the US. But still waiting for the drawing with dimension of the original 2GM+KM2A.
I did measure over the week-end and found an exact match on the total length of engine+transmission and relative to silent-block attchement. So I am quite hopeful, but I am still a bit baffled of why the 2YM15+KM2P-1 would fit a J/30 model 79 and not a model 84. So your pic and model would help..
Regarding the propeler pitch adjustment if a KMP2P 3.22 was choose - it makes sense - but I intend to stay with the same ratio (2.62) as the original setup - as mentioned also Bill...
Will update the thread when/If I managed to have the original 2GM+ KM2A drawings...
Cheers,
