Water cooled V6 with glow ignition and I think the carb induction has the rotary shaft to separate the intake ports from each other in the pair configuration. As mentioned also the shaft looks like 1 to 2 ratio which may get away from the regular 2 stroke as it might not fire on every stroke. I know the 4 stroke RC engines use the F type plug which will glow longer because of the deep chamber in the glow plug. Very interesting with all the comments and actually would be nice to see the parts layout. Was on the site and could not find that engine but there is a 4 cly. in line engine which looks like the same setup.
For lubrication it may have the old style splash system with no pump or oil mix in the fuel. For cooling in a boat and used for racing which the company is
advertising for It may be by pressure from a scoop on the hull. Most of the model glow engines water cooled in high speed boats are that way.
Your english is great wish I could do the same in another language.
