Re: Yanmar 2QM15
Sounds odd. What's different between the two? Is it the bolt pattern to the bell housing?
My concern would be over the gear reduction ratio, if it doesn't fit properly. Gear models are made with various reduction ratios from engine to prop rpm. Perhaps the mounting pattern differs between them too, so they wouldn't be interchanged?
