The exhaust in my outboard comes out of the front of the middle unit. I looked at the unit and corrosion has opened a hole in the middle unit. Engine is a mid 90's. It runs fine otherwise and starts every time. I spoke to an outboard repair guy and he said to remove the powerhead and check the bottom for corrosion. If there is none he has a middle unit that I can buy used and put on my existing motor. My problem is when I removed the 6 bolts connecting the powerhead to the middle unit I can not seperate the powerhead from the middle unit. Is there anything else holding the two together? I downloaded the manual from the Nissan website but it does not give me any help in this situation.
