If it is just you and your wife, your have a shot at the drive living. Drive parts like Max Machine makes will help. Put 4-6 adults in your boat with a cooler.....you know the answer.

Just buy a spare and then slap it on and keep on going. Rebuild- Repeat

These threads start every year late winter when guys building bigger power start thinking about what they're hooking it to.

The title first made me think "April Fools !!!" but I realize it's no joke.

Been there, done that, got the bucket of parts and pile of Bravo rebuild bills. Never again.

Is the Imco SCX the only option ?

Really hate to have to tell the wife we need a $15,000 drive on our $7000 boat....

There are a few corsas out there with arneson drives and they work/ run very well. Bravo simply will not last, it will work but won't last. Look for an older #6 arneson but even that will be on the edge with 800 hp. Good luck

x 1 million.

I talk about this all the time.

I've broken plenty of Bravos on a handful of boats. Each time was overloaded with people and gear.

Modified motors and stock 502MPI's.

Regular Bravo's though.

====================================

Boating has become much cheaper since not loading boat up with people anymore.

Less fuel.

Less Drives.

Less Beer.

Less being stuck with the restaurant tab. LOL.

I have about 850 HP in my boat , originally came with 625HP , well , shortly after upgrading power , about 30 hours ...Bam ! Rebuilt drive at an expense of 5K , next one lasted about 35hrs , this was and IMCO SC drive , which is basically an XR drive , I said screw this , put on an IMCO SCX drive and now have peace of mind .I lost about 4mph on top end though .

You can put all types of snake oil in the Bravo, Polish the gears with Mother`s , freeze em in your freezer, shower them with love but at the end of the day the gears are physically too small for anything much more above it`s intended use.

Every hot rodder thinks he can build the fastest boat until he learns how much drives, props and jacketed exhaust cost. The boat and blowers are the cheap part.
