Are the drive XR's or regular bravo's? Pics of the set up?

1 poker run, wasn't rough, 2 boats, moderate power 3 wrecked bravos. They're great.... For drive shop business

I've seen guys with moderate power less than 700 get Bravo's to live for a little while on larger heavy boats. Usually replacing lower gear sets every other year. If that is reliable then your right. But do a couple poker runs running hard in rougher water and those gear sets may last a season. The 800sc will eat a bravo alive due to the torque not the horsepower. Raising the "x" will only make things worse. Your best bet would be to go with and Imco SCX drive which can take the high power and torque.

I know this isn't what you want to hear, but after 4 or 5 drive rebuilds and your wife screaming at how much money this thing is costing you will be ahead.

Going with the IMCO SCX uppers and -2 lowers would likely be the hot ticket. You might be well served with the SCX-4, but I suspect you'd want to space it down a hair.

I agree with the the others, B1/XR uppers will not last long on that boat with 800SC's!!!

they reg bravos

I cant see why a bravo drive with a beefup upper case and a sprortmaster or imco lower wont lasts

You're going to be eating B1's like they are are popping out of a Pez dispenser! Strengthened case or not, they still use tiny junk gears which are the weak link in a B1/XR. The SCX uses a much larger gear set. Switch to the SCX while you're B1's can still be sold as functional drives and have value, this will take a lot of the sting out of paying for the upgrade. If you don't change the drives, prepare to be this guy...

take the blowers off, put intake and carbs on and enjoy your ride

Maybe they will survive, keep us updated I'll be the first one to tell you I was wrong.

Homer Glen ? That means you`re going to be boating on Lake Michigan?
