OEM 155 pump measurement needed

[yamanube]

Hopefully somebody here can help me out. I am trying to figure out what driveshaft I need to put a stock 155 pump in my Maxx hull.
I have received a measurement from a Maxx setback pump from the face of the wear ring to the end of the splines (see picture below, not of the same pump but what was measured).
I need to know what the distance is from the face of the wear ring back down to the face of the stator hub.

Call JetManiac he should be able to hook you up with the correct shaft.

If the MAXX hull, uses normal 96-07 shaft for lets say 144 OEM pump.
You would need to get a shaft, that is +15mm longer than the stock OEM 96-07 shaft.
The 155 OEM stator sits 15mm "setback" compared to a OEM 144mm pump.

I've had this situation / setups a few years ago. OEM 155 pump in a KDX hull
You can run stock OEM 96-07 shaft, but your spline engagement will only be 25mm of the 40mm - hence why the shaft needs to be +15mm longer
