How much boost? FYI, those XR drives will be toast in a heartbeat with this power. They will not come even remotely close to standing up to that power. If you're smart you should sell those XR drives while they're still good (have value) and bolt on a complete set of Imco SCX drives. I would also suggest going to the SCX lowers with #6 shafts on this project. You're going to need the larger propshafts and #6 props.

No idea what you'll need for props until you can give us an idea what you think this will make for power, once we know this we can get you in the ballpark. Just taking a stab in the dark and saying these engines will make 900hp, the boat will run around 112-116 mph (depending on drive setup and height), so you'd need something like 35p or 36p props at that power level.

Until you swap out those drives, I'd leave some small props on it, this will extend the short life you'll have with the XR drives. Honestly, those things wont last long at all behind your new power... get them off the boat ASAP!
