I have a '97 40 horse johnson. I just got it at the end of 2012 on a 16 foot sea nymph. It had been sitting for a year then. I didn't mess with it 'till a couple months ago. It was smoking real bad upon start up when I ran it in the driveway with hose. The smoking went away after a few minutes and it seemed to run fine. I put it in the water a couple weeks later and it again smoked real bad, but did not get better. It seemed to get worse so back on the trailer it went. I read a couple posts here and disconnected the oil line to vro, capped off the inlet on vro and mixed gas 50:1. Ran fine on the driveway and in the water. Just a little slower than I thought it would, 17 mph. Is there an adjustment for the vro or is it just shot? If it is shot, just what steps should I take to run with out it?
