Bill Zuber just PM'd me with the same question. The below is a nutshell of my response. I am looking forward to hearing the other side of the argument as it may open up potential future possibilities.
Rule book states:
"2. The powerhead and lower unit must be of the same manufacturer and model."
The confusing part is what constitutes a "powerhead" If the power head is simply the case that says "XM" then you are correct in you thinking, but if the "Powerhead" is the entire working engine that is mounted to the lower unit, then a .21 RG (albeit only one part) is certainly not the same "Model" as a .21 XM. They are two completely different parts, one is ABN and one is ABC. The RG was never made into a power head, and the RG parts dont just "drop" fit in the XM case.
By your way of thinking (Not picking on you Mike, just expressing my thoughts) I could install a NovaRossi SS Piston and Sleeve, Titan Rod, turbo cut the combustion chamber, custom built crank and timing etc. etc. and go out and set a record in IMPBA Sport Outboard class. would this be legal??? Because we have already done some interesting things with a XM....
The way I read it is if you want to cut on the stock crank or on the stock sleeve, piston and or combustion chamber, then you are free to do so, as long as the outward appearance of the motor, exhaust outlet and intake inlet do not change or go above specified limits (i.e. a Geraghty carb on a XM...)
