     I've seen it done both ways, but most commonly one motor is 
reversed.  Every reverse-rotation Crusader marine engine I've seen is 
PLASTERED with caution stickers about its rotation and not to set the 
timing too far back.

     A marine mechanic I spoke to said the only difference between a CW 
and a CCW motor was the cam and the starter - makes sense.  He also 
mentioned that the reverse motors usually had a hotter cam since they 
didn't make as much power as their normal rotation cousins.
