Getting ready to to a compression test and leak down test on all 6 cylinders. Boat has ran fine for the 3 seasons I've owned it. When changing manifolds this spring I noticed this exhaust port. The center port exhaust port looks to have some deep rust? What does this photo tell me about this cylinder? Water leak in the past? '90 era 4.3L.
