I recently bought a new 4-stroke 40hp Honda outboard (with a prop). I have only used it 8-10 times. Yesterday I noticed that when I came to a stop in the water (in neutral), there was a lot of gray exhaust coming from the exhaust hole, but eventually stopped as I started driving again. Is this normal? Maybe this has happened before, but I didn't notice??? There is usually some gray smoke, but this seemed like a lot.
Any suggestions what this could be? Or, is this just normal exhaust, and I'm worrying too much? Could it be water in the gas, problem with the oil, ect.?
Thanks for your help!!!
