I have a 2012 high thrust 9.9 and it was submerged for over a month in fresh water. When I pulled it back out of the water I cleaned and drained everything except the leg oil. I sprayed seafoam in the crankcase and carburetor and put fresh oil in crankcase. It fired up and ran great on the stand. When I took it out the engine oil light came on after 5 minutes and the motor began to run extremely rough. I managed to limp back to shore and when I checked the oil, it was perfectly clean and at the correct level. I put it back on the stand, hooked up the water hose and started it. It ran fine for 5 minutes and once again, oil light and rough underpowered operation. What else did I miss cleaning and how do I clean it?
