Im looking at some used 500hps.

you don't need XR's then with 500 hp's...what props are you running now?

The same 23 pitch mirage from my old bravos

so if they are old props how did you change the inserts????

I told you I changed nothing everything fit

dude...XR's have a TOTALLY different prop shaft...diameter and spine count!,,, how is this working??? my guess is (the one i've seen enven a dealer make ) is that your prop is slipping on the shaft....i even saw a prop walk right up into the case and whiped it out!!!....

I just pulled a prop . There are 15 teeth on the shaft and 15
groves in the hub.I dont see any sign of that.
Maby I dont have what I think I Do.They have low water pick ups
in the bullet and I was told they are XRs.
Do you have a number I can call to talk to a Merc. rep or someone
who can tell me what they are by numbers on them?

what does the the serial # start with OL, OM??? hope you got a kick ass deal on them!!!?

you may have an X?...but you have to check the SN

17 is a XR AND XZ

The number starts with OL and I havent paid for them yet.

they are not even X drives...they are the HP series LWP....you can upgrade the gear set with a taller floor gears later...really hope you did not over pay!!
