Re: compression reading.
Most OMCs like compression around 95-110 lbs. Compression is not as important as the difference in compression between cylinders. Rule of thumb is %10 is OK. One other thing compression readings can vary quite a bit from guage to guage on the same motor. I was reading a post where the difference was nearly 25 lbs on the same motor with two different guages.<br /><br />Also check the red search at the top of the page. You might try "70 hp compression" as a search arguement.
