This may be a dumb question, but how do you determine where "straight up" and "straight down" is when clocking the props?
I have the documentation showing the clocking procedure, but what is not clear to me is, what part of the prop do you look at when determining the up/down positions.
If you take it from the base of the props, you get wildly different positions than if you take it from the tip of the props. The same holds true if you take the up/down positions from the front, centre, or rear of the props.
I have mine clocked so they appear to be the same as in the clocking diagram, but I have what I feel is excessive vibration. Of course I can move it one spline left and right to test, but I'd prefer to get it right before I put the boat back in the water and avoid the testing.
