I needed to rebuild my lower unit and since I don't know the history of the motor, i decided to replace the water jacket gasket and head gasket. The water jacket had a what felt like a metal gasket on it and it came off in one piece. The head came off with no fight at all and doesn't appear to have a gasket at all, just a coating of what looks like blue sealant. Its very thin, not rubbery like RTV. I don't think I've ever seen a head put on like this. I havent tried to remove it, id though id ask first.
Also, on a side note, I removed the thermostat cover and found these two relief valves. According to the schematic it shows only one, but the part listing says 2 are needed. Just an error in the book or is this engine cobbled together with mismatched parts?
I attached pics of both the head and the thermostat cover.
Any thoughts would and are greatly appreciated
Thanks in advance
