Here are some pictures description below:
This motor appears to be a 1990 3.0 (181 140HP) after much searching online and referring to Mercs bulliten (http://www(dot)boatfix.com/merc/Bullet/97/97_06.pdf) on engine identification, I cannot for the life of me figure out the proper serial of this engine. You can see pictured the casting marks which read: 14096613 72/90 and of course it was cast in Mexico where Cervesa is plenty and Tequellia is cheap.
According to the Engine code:M03210H0 which has a zero as the 6th digit signifies either a 70,80,90,00 as this has a 1 piece rear main seal it is obviously newer than a 70/80 and where it takes a 12 3/4" FW it is older than a 2000. So, I know it is a 1990 which leads me to my final question:
What is my proper serial number so I can figure out what flywheel will work with this engine?
