For all of you mercury grurus, I have my p4 pending sold on here. It has a 2004 200 EFI 3.0L Motor on it. They gentleman asked me to do the compression test. I did this at home and received number of 102 to 107. The gauge is on from auto zone, with o-ring seals for hand tighting. In the manual it states 90 to 110 is spec. I had a local mercury shop change the water pump, lube and go over the motor. They did the comp. check and told me all was great at 130 across the board. The shop told me that all is good and dont really look at the number as long as the numbers are with in 10 of each other and not really low. What is spec and what is the opinion of this? Thanks for your help,Eric
