Firstly hello as this is my first post and just wanted to say great site.
I have just bought my first boat and it has a Mercury Blackmax 150hp V6 to assist me in getting around in a timely manner. I decided to do a copression check just because i wanted to get to know my engine a bit better and dinner was out of the question. I am getting bang on 100psi on odd bank and 110psi on even. I know that this is a good reading as far as differences in cylinder pressures but overall is 100-110psi good for this mid to late 80's engine. Any responses gratefully recieved.
