Peter,
Unfortunately I had the same problem 2 years ago the sumlog when working was
superbly accurate. I fitted an electronic Raymarine log which lasts about a month before sea creatures make their home in the impeller and it stops, it also very hard to calibrate.
I have the wire from the impeller and the clock if by chance that part is at fault.
