Hello I'm a complete newbie to owning a boat other than the basics I just bought a 1990 astro quickfire 19 fs it has a 1990 mercury v200 serial number oc283691 the guy I purchased it from caught a rock and destroyed the lower and mid unit My question is what year motors can i get the parts from i found a EARLY TO MID 80's merc 200 complete will it work? or can i use parts off a 150 and what years? everything i'm finding is just adding to the confusion
