RE: RCV 4 stroke???????????????????
Rick, I do have one, it turns a 12x6 three blade at 9,000 rpm and is very smooth, I have run it on WildCat 10% premium with 16% lube and WildCat 15% Premium Extra with 18% lube and with a Fox miracle plug, OSf and H9 Super Plug. It runs the same no matter what. It had a slight gear whine for the first 30 minutes and that is almost gone.
