I currently have an 175 hp Mercury on the back of a 19ft deck boat. I have read here once in a while, someone will mention Klotz mix. Has anybody ever used Klotz mix in an outboard or can you use it. we currently use it in our 2 cycle off road bikes, but I didn't know if we could use it on outboards. Can anyone out there share any information on this. If we could use it I would perfer to because of the way the engines run with it. They run so much better with Klotz, at least thats been our experience.
