Re: Yanmar 2qm15 smoking in gear


I ran her three hours on clean fuel with the Power Service injector cleaner last evening at the dock. I varied the idle speed a bit, I did find that when I ran the engine faster that I got a little white smoke. But none otherwise at idle. Didnt try her in gear.
I didn't leave the engine running fast for any length of time!! and I varied between low and medium idle every few minutes.

I'll run a few more hours today and then test her out to see if there is any difference.

I hear what you're saying about the fuel, and diesel mechanics are hard to come by in these parts (rural canada). I already pulled 9 gallons of old fuel from the tank prior to launch, but I didn't get it all.

thanks again!

Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off your bowlines. Sail away from safe harbor. Catch the trade winds in your sails. Explore, Dream, Discover.
