Re: 1989 evinrude 110 vro compression

OMC won't give out a compresion reading. They just say that all cylinders should be within 15 lbs of each other. Yours sound OK, except they may be slightly low in some's opinions.. Several things other than the condition of your motor can affect this. The type of gauge used, the way it's done, etc. You may want to try decarbing your motor if it hasn't been done and try a compression reading again. I personnally like to see them over 100, but that's just my opinion. If your motor's running good, I wouldn't worry about it. Try the decarb though. It won't hurt and can help your motor significantly.
