I do have a question about the 4 stroke problems now. Cars have been running 4 strokes for years and seem to be pretty lined out. The valve train in the 4 strokes should have some sort of adjustment to get the valve train back in spec (nut adjuster, shims, etc.) or have hydraulic valve trains to take up the wear. Do the outboards not have any adjustments to them? Not trying to start an argument just trying to get some info and figure this out. Because if they don't have anything to correct for wear then it sounds a design flaw.
