I am about to purchase a boat with a 2000 mercury 90 hp ob on it and i cant seem to find what the compression should be. I did the compression test and all of the cyclinders are If anyone can help coming up with 95 lbs on each. Then that will be awesome. Thank you in advance

Re: 2000 mercury 90 hp compression

even is great, but they should be higher, over 100, probably around 120+. sometimes a decarb will free up sticky rings and compression will come up.
