Im not 100% sure these are the right ones, I just found them on the web but they look right. I can look in my factory manual tonight to see if they match up. Most all mercury stuff is basically the same far as harnesses threw the 90's to the 2000's. What year is the 150? The newer ones in the 2000's are a little different than the 90's on the motor side. The dash side should be the same.
