I have the option to purchase a 1996 115 Johnson. The guy that has it says the compression is between 105 and 120 across all 4 cylinders. Should I be concerned that at least one cylinder is at 105?
yes max is 15psi. put oil in lowest pressure cyl. and preform test again if reading raises 10 psi then ring job is in your future. or you might try some sea foam soak. in that cyl. for a day or two.
