Thanks for responding.
If it is water causing the misfire should we
expect some indication of that on the spark
plug? I put the seals in the motor in the
winter of 16-17. I don’t remember if there
was a hole in the bottom seal. I may have a
picture of the seal I put in. I’ll check to see
if I can find it. What would be the best way
to check to see if it is oil collecting in the
bottom cylinder?
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
