This is interesting info about the current generation of OBs...nothing like having an expert chip in. Your information about the 6HP being a single cylinder is surprising and disappointing...I have not been much of a fan of the switch to 4 cycle motors...more wieght/more cost/less power. It all makes me treasure even more the Tohatsu 8HP 2 cycle I have on my RIB.
All given, I'd say look hard for a used 2 cycle 8HP rather than pay the cost and live with the weight of a new 9.9.
