yes yamaha makes a 60hp 3cyl, with the 60hp carbs (same as a 50hp) a hot 50hp yam or hot -sue mite stay with it. can a ricer 50hp make as much hp as an OMC, NO,they are small up dated copys of the OMC's, what works on one works on them all, you can put a divider in the side transfur on any of them.:cool:Quote:
back to the real question.
Did someone say popcorn?:p
With a divider, the overall transfer port can be wider. A port opening can only be about 65% of the bore in width or the ring will grab the edge. Also, with a divider you can better direct the flow. And, you can increase the velocity as needed.
Might ruin a few blocks experimenting.
Go slowely,
