[QUOTE="ol sarge, post: 324225, member: 7670"] I have a 74 20hp Mercury that was doing the same thing. I replaced the prop and it ran fine for about 15 minutes then it gave out on me. Turns out it was a bad drive shaft. It is in the shop right now. Its about a $200 job to get it fixed but once you get it fixed, it will run forever. [/QUOTE]
