Hello,IU have a 1969 35hp 350 mercury outboard, Motor serial number 2672267. I had to remove the flywheel and did not mark where it was.The outer part came loose for the part that has the key.The eight bolts were removed. That let the flywheel become seperate for the part with thw key. My question is : Where are the timing marks on the motor and on the flywheel? In other words ,I have to put the flywheel back on the part with the key and find the marks to set it right.
