Hey guys, I am trying to find out what my x dimension is on my 28 single, and also what it needs to be. It has a stern powr drive so referance points on the drive will not help much. What is the best way ( or the standard ) to measure
this ? I do know that this drive has a 21.8" shaft to shaft dimension. How far does the prop shaft need to be below the bottom of the v on the hull ? The boat does not have a notched transom. Thanks in advance for the help, Scott

from my experience, the prop shaft should be between 4 and 4 3/4 inches below the bottom

Thanks Bruce, Is that with a notched or regular transom ?

regular transom...no notch

What kind of prop slip are you seeing with that setup ?
& with what props ?

i run a 26 B-1@5800 we're seeing around 16-18% slip

I'm agree with Bruce on the #'s he posted. I have a nothched transom and am in the 4.25-4.5" area with slip #'s in the same range. I was 1" higher before and couldn't carry the bow enough and slip was higher.
