I think this is exactly what you want. Like Rex said, the crank and pump shaft should be in line horizontally, and a few degrees off in the vertical. The way it was explained to me is that if there is not some angle difference, the U joints will ride on the same needles all the time (the shafts won't turn in the cups) and this will lead to U joint failure.

That is what I have always heard from back when I was lifting trucks. I don't recall why I took that pic, think I was looking for a driveline cover or something. That is how its been since I got the boat & it has been perfectly fine. Regardless, I couldn't lower my motor anyway, as the pan is pretty close to the floor as it is....
This link may help you guys. It is in the list in Gear Heads > tech links also.
