I have a power problem, in forward gear. The RPM's are fine in natural and reverse. I have changed oil/gas and lubed the lower unit and lubed the zerts on the shaft. After looking into this more is it possible that the vent was not all the way open, (I mean it was not dangling loose) It was backed out most of the way I am going to try it today. PS sorry for the type O's in my first topic.Thanks to 12 footer and others that have replied so fare.
