The DNR Commissioner has approved the new regulations to allow 50 h.p. on the Kenai River (KRSMA). This will go into effect on March 1, 2008. The rules on overall boat size remained, limiting boats to 21 feet in length and 106 inches in width with a grandfather clause in effect until 2010.
The older 2-stroke motors are allowed in all months except for July and the year for total ban has been eliminated from the regulation at this point.

So, if you are pro or con (frankly, I was ambivalent on this issue), there is closure to this issue.
