No spark on no.1 top coil. Have swapped coils around and still no spark at top position. Engine is 3 cylinder. I am based in North Wales UK.
The fault occurred when I was using boat - it was running well at high speed. Suddenly it just lost power, thought something was caught on the prop. Managed to get ashore running on 2 cylinders.
Compression in top cylinder is still good.
