Re: Mercury force 120 DFI, No spark!
got the boat and heres what I found out so far. The powerhead was replaced with a quicksilver by mercury repower 120 force year is 2000. I got good spark the emergency kill was corrided a bit. The starter is very weak but did get the motor to pop. Heres my real question, The compression readings were 120, 120, 100, 120. The weaker cylinder being number 3. Will this pose a problem? The motor and boat are extremely clean but not sure on the engine compression. Any advice would be great! also the power trim leaks down from the raised position?
