Re: compression

IAccording to the standards from evinrude , there should not be a variation of more than 20% from the lowest to the highest cylinders. IE the lowest cylinder reading must be 80% or more of the highest cylinder reading. 92/117= 79% might wanna look at a ringjob

Yep, those numbers are not good. I would first try the decarbing procedure to see if the numbers improve.

Procedure is under the Top Secret files.

Re: compression

I agree with the de-carb. That should bring it up to snuff. Especially if you have never done it before.
