I would think that Captain Kirk knows about the x-dimension, If not Spock knows for sure. :p

My Ex Wife :lolhit:

Was she BIG?? (Dimension Wise?) j/k Lol

It is really from early boat building days when they measured the transom for the drive cutout. They would mark a line straight across the chine (looking at the transom) and measure up from there (Not from the running surface like they do today) Then measure laterally out from center (after finding the transom center) for twin engine boats, and just using the center for singles, They would mark the spot to drill with an "X" hence the X-Dimension....No Sh*t :)

I thought it was the X you draw on the bottom of the boat when you found a good fishin hole ...... so you can find it again .....:eating:....:fish::fish::fish::fish::fish::fi sh::wuerg019:

Correct


Incorrect.

:lolhit::thankyouthankyou:That's it!

it is eally all about the propshaft centerline to keel dimension. BUT, you arrive at it by putting engine in it at a certain height (x-dim) so that with your drive length your prop is where you want it to be. assuming you can still close the engine hatch.

yup.

Crankshaft of the engine?
