SXR Solas pump clearance

[XFT LOU]

Hello
After installing a Solas mag style pump on a SXR
We have coupler gap.
How do you keep the drive shaft more forward?

Put a piece of heavy 3/8 hose in thr impeller. It keeps the driveshaft pushed forward into the coupler

Thank you.
We shall do just that.!!
