The drive would be part a winter project.... I have a naturally aspriated 598 that I may put in this winter.... Dynoed a little over 700 HP.... and as I said I can get a killer deal on this drive so I would be willing to give up a couple three mph for the reliability.... the whole project is still up in the air though... the boat is running great the way it is & I am reluctant to mess with it... but that HP sitting in the garage is really tempting me!

I appreciate everyones input.... thanks

I rebuild my XR every year and no problems, and I run 50-75 hours per season. Good luck, keep us posted.

Having a spare drive is a good idea along with that you need someone who can rebuild them . Not your local searay dealer but a good performance shop. 598 GO FOR IT

Is that the old style bottom, Gary?

Also, did Boyd build the 700 motor?
