While reading the Seloc manual the the seller of my Bayliner gave me, I see he noted that some compression test readings were 35, 75, 100. 
Gues he had some motor problems.
I did a test and go 130, 130, 130, so the previous owner obviously had the cylinders bored/repaired around 2000 or 2002. Nice, knowing the motor has new pistons, rings, etc. But the Seloc manual says the compression for all 85 hp models is 150 to 165. So I'm wondering why mine has 130 on all 3 cylinders. I doubt they have all dropped evenly, so my guess is that the new pistons put the compression at 130.
Does anyone have a Chrysler/Force OEM service manual that lists the compression for this 1985 motor as 130 or so?
