Re: 1998 200hp ocean pro
Chris, I am currently attempting to remedy that exact problem with my mid 90s 60 degree 150. You should watch my post on the subject, I am waiting on some gel seal II to arrive so I can re-seal the crank case. this is the second 60 degree 150 that I have owned, the other one had same problem. I strongly suspect a problem with the crank case pressure, I have torn the motor down and looked for cracks, could find none.
