Re: Xr Drives

Ok, so now I'm confused. I am buying a boat with 525EFIs and it has XZ's instead of XR's any concerns or issues? Anyone know if I can put the XR sportmaster lower unit on the XZ's?????

Re: Xr Drives

xr has straght cut net forged upper gears. xz has angle cut near net forged gears. i run an xz behind 945 hp. easy out of the hole and in and out of the water. the xz is rated at 525hp and the xr 575hp. the xz is a little more quiet then the xr due to the angle cut gears.
