Do it, you have two spare drives.....:D....Ive broke an XR with a carb'd 502 just crooozin along

lol, spares aren’t the problem. Installing the spare 50+ miles from the boat ramp is! Lol

While the Wife is *****ing "this GDam Cigarette Boat" the whole way lol Don't ask how I know.
and Yes I always carried a spare set of drives because they were different gear 1-36 and 1-50 so spare props too.

Went to SCXs and almost 800 HP-and No Problems.

I had my drive rebuilt by AADS and got a 24 month warranty. I had them cryo my gears as well. 3 years later my magnets are still clean. I have a built 524 that pushes my Velocity to 80+ with a full tank and 6 big guys.

Did you get a performance upgrade service? Or just the rebuild of the stock unit?

Reason I ask is I'm having a 502 built that I'm concerned with the stock Bravo I.

I had the performance upgrade. His price was extremely reasonable.

Boat is winterized, and end of the season comp test and leak down have been done. Both engines are still in great shape. They must have been rebuilt/overhauled/top ended at some point. I definitely have time to get the drive thing figured out. Now the figuring. I am going to replace the broken upper gearset in my extra B1, any suggestions on where to get parts? The OEM prices are insane, I can buy a low hour complete drive for the cost of the parts. I want to get into the drive to familiarize myself with the process.
The latest posts on this thread have also got me wondering if having my gears(in the installed drives ) cryo treated is worth it for insurance against expensive breakage? or is it better to use new gears for the process? In which case I would obviously wait until I have to replace gears. I really like the suggestion of just always having a spare drive(or two) ready to go.
