Dropped the lower unit to replace a water pump and noticed a lot of carbon or oil deposits in the exhaust housing. Do I need to do anything about this? Should I just scrape some of it out? I am afraid that cleaning might cause something to get clogged elsewhere. What about the upper portions of the exhaust passages?
