I have an older johnson 9.9 and it cranked fine when I put it in the water inspite of the 22 degree weather. It throttled up and ran fine until I put it in gear, then it would just barely push the boat. It has been fine until today. I ran it 2 days ago with no problem. I removed the fuel line to check for water. There may have been about the size of 2 grains of rice if any at all. Any other thoughts on what may cause this? Thanks
