Hello!

I have a 2007 9.9 pro kicker on my boat that was broken in per the Mercury manual when I had it installed. I've read here before regarding motors "making" oil when used for trolling as mine has been doing.

I've heard of so far 2 remedies for this. I asked about this at a seminar at the Sportshow this past March, and the moderator suggested using Ring Free in the fuel to help eliminate carbon buildup from trolling. The other was to run the motor at near WOT for 30 minutes or so to reduce the glazing on the cylinder walls, and that will prevent the blow by of fuel.

I'm hoping some of the mechanics on here will chime in with ideas as far as if either of these remedies will work, or if there is a better alternative.

Last summer I took 3 fishing trips, and changed the oil before each journey to hopefully prevent any long term effects on the engine.

Thanks for any ideas!!
