That's the bad part! The instructions just say to put the engine mount on without giving me a template or anything to drill to. They also show you how and where to draw the thrust lines but don't tell you why. I'm under the assumption that the engine shaft has to be centered where those 2 line intersect. That's part of my problem, I'm about an 1/8 of an inch below that line. Basicly, I eyeballed it. Has anyone else out there encountered this with a 4*? Is so, how did you deal with it? Thanks
