Does anyone have any experience with a 220hp mariner on an 88' advantage openbow? The mechanic told me that all cylinders were at 120 when he did a compression check. I have no idea if that is good or bad. I just know it's good all six are close. Any opinions on whether or not this is a recommended engine?
Thanks in advance!

120 on all cylinders in a stock engine is great. No worries. I have 89' 200hp Mariner.............(ok, its painted black and says Mercury on the side but it is for most purposes the same) and mine all run between 120-125 if I remember right.
