I have a mid-eighties Merc V150. I am testing the coils to remedy a performance problem. The Merc manual states that resistance should be 800-1100 ohms. I am getting around 230 ohms in each of 5 coils with about 900 in the last one. It seems to me that the one at 900 is the problem but the manual states 800-1100 is normal. Is the spec in the manual wrong.

On another front, what is the spec for the carb floats setting? Thanks very much.
