Hello
I have a 1993 mariner mag 3 150 hp. I decided to to a compression test.
I took all the spark plugs out and measured each cylinder. i got between 70 and 72 on all six cylinders. What should it be? Does this seem low?

Hello Guys
I will try to make this as short as possible. I have a 1993 mariner mag 3 150 hp. The motor will idle great but when I accelorate it will bog down and loose power. sometimes it will try to go but never make full power. I have tested the stator and trigger coil acording to the manual...
