Hello, I'm hoping somebody can help me out. I have two new BF150 25" engines I intend to mount on my 25ft whaler and have a question about lower gear cases. Both of my engines are standard rotation and would like to switch out one to a counter-rotation. As I understand it there are a couple model year breaks over the years, one about 2004+- and one about 2008+_ and I have been told by a couple guys that a lower from say 2006 won't fit my 2011 engine because the shift shaft splines are different and possibly the drive shaft spines are different? Any truth to that, info from the experts would be appreciated!! Thanks in advance! I also see that I mislabeled my engine model, its a BF150 not a BR150, whatever that would be! Damn fingers!!!??
