It's a mercruiser 5.7. After I let the battery charge up so that I was getting a healthy turnover, I'm getting #1-170,#2-170,#3-165,#4-175,#5-160,#6-135,#7-165,#8-170 and # 6 is 160 with oil. Should I be concerned with 6?
Merc 5.7
I got a 125 readind on one of my cylinders when I turned it over with a low battery, but it went up to 175 with a fully charged battery. Is this common?
