They will last between 5 and 1000 hrs depending.

Ah Griff, but if you're a true idiot with a heavy boat and / or lots of power, I'll bet you can get less than 5 hours out of one. Sadly, I've seen it done.

So you think 6.5-7k is cheap for an XR replacement without transom assy? Checked prices on shafts, parts, billet shafts, gears and props lately? Blow a few and you could just have bought an ASD or Konrad, to which you prefer.

Bravos suck.

Cost seemed like it was around 3500 for rebuild and 5-6000 for new.

He also needs to be looking at the gimbal ring. If its subject to a lot of rough water use the gimbal rings can go at 150-200 hours even on a stock 502 28ft boat. Previous owner had to replace the transom assemblies at around 200 hours on my boat.

One of the drives was rebuilt on your apache. During an oil change some chips came out. so i removed that one and found the upper gears had a piece missing. Replaced upper gears and went thru the drive.

Bear in mind that Fred Kiekhafer himself was quoted a few years back as saying that the Bravo was never intended to handle more than 300 hp. Given that statement, the drive's performance in performance applications is easy to understand... ;)

Heres my experience.....

An Ilmor 710 in a 5 thousand pound boat can wreck one pretty quick in the ocean.

10-50 hours on the ocean with moderate stick bursting to high speed occasionally.

If I keep my arm out of it and boat on lakes 50% of the time 100-150 hours.

Its fragile enough to where if you sending it over 500 HP consistently you should think of sonething else.

I had an old Bravo 1's gear last 10 years with 500HP against it in a 2300LB boat.

Never heard that before.
Great thread by the way. Being an O/B guy my I/O owning buddies all lie to me until I get them drunk. Once intoxicated they state exactly as posted.
500 HP's seems to be the magic # where everything else gets more important.
Hole shots and being good on the sticks in the rough seems to be key from what I hear.
