and yes, it does run on diesel #2.
I guess a few years ago Mercury decided that they wanted to supply the military and commercial operators with outboards that could use a single fuel source - diesel.
Basically its just a 3.0 V6 2 stroke gas engine, but tuned to run on diesel fuel. They don’t run on the diesel cycle, they actually use a spark to ignite the diesel...a thing I didn’t even know was possible.
They say the engines are 95% common with the gasoline 2 strokers. What an oddball motor.
