I have upgraded to BRAVO XR DRIVES AND NOW I HAVE A
HARD TIME PLAINING OUT. ARE THE XR,S A SHORTER DRIVE?
OR IS IT SOMETHING ELSE?

Did you also change prop's?

No I put back on the same props,and I have the same gears
in the drives,and the same power.

what drives did you have? what h2o configuration did you have and what is it now?

I had Bravos that came on my 1991 31 scarab that were
hooked up to 365s. Sorry, but I have no clue about the
h2o configuration

you just bolted up XR's right on your 91 TA's???

Yes, I took off the old ones and bolted on the xrs. Everything
fit.

no, there is a dif....check with merc....your old setup used a castle nut and this one uses a spaner nut....who talked you into XR's....they eat way too much hp for your application...so you had to get new props? or you just changed inserts?

I plan to up grade the motors this winter,and Iwas having
problems with a drive , I ran across a deal on the XRs and
I thought it could not hert to put them on for the last of our
summer

what engine do you have and what are you going to (HP)?
