Gearbox/redrive weights reference

Hey everybody,
I've been a longtime lurker on the forum, finally decided to jump in to the conversation!
I've been trying to find information on gearbox weights but have struggled to find good definitive weights.
I wanted to reach out and see if any of you know the weight of one of the common gearboxes/redrives. I'm especially interested in Stinger, Ballistic and oxbox as those are the main ones I've been researching and considering. Thanks!

Running list for future reference:

Stinger: 66.2lbs (weighed by Waterthunder)
Ox box: 68lbs
Rotator: 70lbs
CH3 Belt Box:132lbs (Weight breakdown in comments)
Precision (airboat gear drives): 66lbs (manufacturer reported)
Torque Drive Gearbox: 70lbs
 
If I remember correctly the Stinger gearbox is 73 lbs. I'm not 100% sure about ballistic or oxbox but I've installed both of them and I would say they are pretty close in weight to the Stinger.
 
always worth repeating on the weights of gearboxes

CH3 Belt Box
Upper Unit----60lbs
Lower Unit with bearing----23 lbs
Main Housing-------42lbs
All bolts and belt----7lbs
Total---------132lbs

Rotator Gear Box 70lbs
 
Thanks for the replies so far, I just wanted to add that I'll be updating the list on my OP so that it can be used as a reference by myself and others in the future.
 
OX Clutched or Direct with or without fluid?
Total package or no bolts?
Weights usually apply to gear to gear or belt to belt, but if it's hp loss to gear drives or belt drives, that should trump weights any day of the week!
 
To date, nobody is willing or financially able to test thrust on the same motor on the same boat per gear or belt or prop or rotation!
The real fucker is will a hull run better with a belt or gear with everything exact?

I'm stumped but interested, any chance you can fill us in on the details?
