Raised x
 

What does it mean I hear guys talking about it

If i remember correctly you really mean Y dimension. Its the height of the drive relative to the hull. Correct me if im wrong but higher Y, more speed.

its actually called x dimension,, and yes its a raised drive and center of the crankshaft position which will increase the speed of the boat..

I knew i was wrong. Kinda weird if ya think about it. When your looking at a graph the x dimension is always left to right. Oh well.

Hey this is boatworld. Looking for logic???:lolhit:

Nah, it's all good. If you don't ask, you don't get an answer:ernaehrung004:

its not even called X dimension since the X dimension has nothing to do with the hull its the distance between your crank centerline and PROP..but many just call the hull to prop hight X dimension.

And it doesent nessereraly mean that you gain speed, depending on boat and which drive / prop your using !

BUT OH WELL:coolcowboy:

If you think up about it. Up and down is the Z axis.

My understanding is the the X dimension is the CRANKSHAFT centerline to the bottom of the hull. The PROPSHAFT centerline to the bottom of the hull can be changed additionally with some brands of offset extension boxes and shorty drives.

Here is your traditional 3 coordinate plane.

if your looking at the hull from the starboard side then Y would be the drive height, X is nothing, and Z is the distance from the transom.

But i have a feeling drive placement is measured from a transom view, not from the side. So in that case you would only use 2 coordinate planes which is only X and Y. But Y has always been the vertical measurement. What way are designers measuring the hull that X is the vertical measurement

This doesnt help because all of that is wrong.

I dont know, im thinking out loud here. Any other ideas? haha

Good information so far, technically if you raise the x you are raising the engine and transom assembly. Raising the engine and drive height will get you more speed, to a point. If you go to high you will not be able to get your boat on plane and you will have the prop blow out all the time. You can also raise the prop depth by using a shortie drive. Last year I raised my engine up 3" and gained about 4 MPH.
