I pulled my 1974 165 merc out to replace the transom on my chieftain. I have never had it running yet , it has been sitting for about 6 yrs out of water. I did a compression test they read 180/145/160/150/60/180. I sprayed the cyls down with bolt loosener. I am hoping that they will even out after soaking for a couple of days. The fellow I bought it from said it always ran good for him. I am slightly concerned about the 60 cyl . I am hoping that after it runs for a short while that the compression comes up to close to the other cyls. What are your suggestions for this situation?
