I cant see where you would loose any hp with the gear change...I've heard that the straight-cut gears rob about 20HP or so.

I cant see where going from xz gears to XR gears in the same drive would make you loose anything. Almost the same surface, friction....I dont see it, but who am I to say?!
That spec was from Mercury when the XR was launched...I'm not a gear expert...maybe Dave could explain the difference between straight and helical-cut gears.
Or maybe it's the way the straight cut gears are submerged...
It was easier to see when Merc was offering a whole package...the propshaft HP was 25 less on the same engine with a XR drive vs the XZ. Now, they mix them all up...
Either way, who am I to say?
