Greetings. I am a newbie to this site.
I have tried to find this information on the web, but cannot. I would like to know how many foot pounds of torque the various flavors of Bravo drives can reliably handle.
Also, besides the price, what is the difference between a Bravo diesel drive, a 'regular' Bravo and an Bravo XR? Are the differences worth the price?
Thanks.

I've run over 600 for years on the same drive no problem. Remember, it's not a dragster, be nice to it and it will be nice to you. I'm uping the same drive to 700+ this year.

It's all in how you treat your drive. I can tell you a stock 330 will break a 1997 bravo 3 if the drive is abused. I don't slam the throttles forward at idle, but I have twisted a driveshaft jumping a wave and later sheared a verticle shaft by accidentally shifting into gear when my secondaries were stuck open at start up (corrosion on the carb after one of the plugs on my thermostat housing corroded and misted the engine for a couple of outings before I discovered it, guess I didn't lube the engine down enough after cleaning the salt off) Snapped the vertical shaft cleanly in two. Looks like someone cut it with a very fine tooth saw. My mechanic and I were fighting over who got to keep the parts, I find used mechanical parts with a history make great paperweights/conversation pieces, he had never seen anything like it and wanted to mount it on a plaque and keep it as a lesson for other customers.
My mechanic told me while he's happy to take my money, no more wave jumping in a boat that tops 12000 lbs loaded with fuel, water and gear unless I want to see him more often.
I think the bam marine website shows the differences between the drives. I think the heavy duty drives have stronger shafts and additional support for the bearings to prevent distortion of the housings under load. I had a heavier shaft installed as part of my repairs.
