Hey guys had a quick question see if anybody could help I have a 2012 mercury 9.9 four stroke and just this last time I was out on the water I noticed it was putting out white smoke a little only while in idle when put into gear it doesn't smoke at all. Runs perfect starts perfect. This is my first outboard so I don't know if this is normal or not. Iv read anything from maybe I put too much additive in the fuel to something actually being wrong. So I thought I'd get some advice from the pros before I took it into a shop! Any advice would be great!
