i accuired a old chrysler outboard. model 355hc serial 3461.35 i know its a 35 hp.and the year is somewhere between a 1966 and 1976.can any one narrow it down for me.the 35 hp's are broke down into year groups for parts,so i really need tobe alittle closer than 10 years.also i've visited many sites listed in the forums and i cant find a "hc" in any of the model no's.i know mercury now owns chrysler/force and spoke with local dealer about this.thier books only go back to 1970 and no "hc" in their books.so i can only assume its 1966-1969 year.<br /><br /> the motor dont need much but i may need parts in the future.how hard is parts to find for these beasts.i also have a 1971 mercury and many of those parts are no longer available,is chrsler the same way?
