Hi folks,
Just bought a boat with a 1986 Mercury 115 hp 6 cylinder outboard. I used to deal with I/O setup and this is my 1st outboard and need help to build a quick learning curve. The engine is running strong but with lots of blue smoke. I plan to do decarbonize using Seafoam but not sure where to spray in or should I add it to the fuel. I will replace spark plugs afterward.
Any tips or advice are appreciated greatly.
