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

Gort, do you think the Sportmaster lower will be anymore reliable than your XR lower? I would buy a spare XR and run the snot out of the drive. At 700 HP I would think the drive should hold up fine. I rebuild my XR every year and no problems, and I run 50-75 hours per season. Good luck, keep us posted.

That makes good sense Gary.... Like I said I have a chance to buy this thing really right.... maybe now I know why? I run the boat on a lake & don't really "tax" the drive anyway.... so I have to agree with you the XR will probably last a long time... thanks....

Gary....

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?
