keeping plugs clean?

Hey guy's i just had onother three year physical on the e-tec  ( replaced plugs ,impeller, and foot oil ) but when they gave me the old plugs back they looked pretty carboned up. I always run super unleaded fuel with star tron ( blue bottle) and marine sta-bil, and even some of the royal purple MAX-CLEAN which is a synthetic cleaner for fuel system and to keep valves clean on 4-cycle engines clean.Is there a secret recipe or some magical potion that im missing to keep my plugs and combustion chamber super clean?

Evinrude's Carbon Guard is the only factory approved carbon cleaning additive recommended for your E-TEC. Using it occasionally keeps any  carbon from builiding up inside the combustion chamber and on the tops of the pistons, if needed.

 

Using a cleaner type of engine oil such as Evinrude's XD-50 or the synthetic Xd-100 minimizes any buildup and really negates the need for decarbonizing.

 

Your motor has to be in a good state of tune, idle at the proper temperature, and be propped correctly in the upper half of the rpm range. If you have an older engine, make sure the software is up to date and that the latest spark plug recommendation is adhered to.

The 60 hp E-Tec in Question regardind the fuel additive is Serial No-5213696 and the Model No-E60DPLSCB, the plugs they pulled out were the CHANPION QC10WEP, and that was the same plug they just put in.

Re: keeping plugs clean?

Hi, just wondering if your 60 is a 2008 model or 2007. in 08 area, they switched to bip injectors and changing the ignition firing style. the bip injectors would be more sharp cornered on the top and say "etec". Did you have any running issues with the motor leading up to the plug change?
