I am a first time boat owner and its a fixer to boot. I have a 1969 Merc 650 and a spare for parts. I also have the repair manual but I still cant find what I need to do. I am changing out the lower units because the housing was broken on mine. I am not sure of the directions to install the following parts .
As you can see the pieces (name?)with the arrows are installed opposite of one another.
The white one was installed that way when I removed the lower unit. The black one was on there the way it is but it was removed from the motor when I purchased it. My question is of the two which one is installed right? My second question is the other part in the picture marries up with it and what direction does it go on? And my last question is does anything need to be turned into a timed position before bolting it back up?
Sorry I am a novice but would really like to get on the water to fish. I am sure I will have more questions so thanks for any and all help in advance.
