I had bad compression on a couple cylinders so I pulled the heads. There was a hole in the head gasket between two cylinders. I pulled the other side off as well and the gasket was really thin in a few spots. I put two new gaskets on and torqued them to 20 ft.lbs in three stages. When I...

Hello All,
I heard someone saying that there is some adjustment or something that you can do to a 70 HP Evinrude outboard that will make it a 90 HP. He didn't have any of the details but was told this by some boat mechanic. Has anyone heard of this or is this just BS.
Thanks,
