I have a 115 suzuki that had similar issues. Checked all the fuel issues and found nothing pulled spark plugs and didn’t see any apparent problem with those but put new set in anyway and that fixed my issue . Engine was just over the 20 hour mark also. My boat sits on lift and if I left motor down it would woof smoke when I started it . Seen post that said trim motor a bit when shut down and that took care of the smoke issue ,guess the oil getting on the plugs got to them .
