Gearbox/redrive weights reference

Post by Cracked_block »

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.

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 ****** 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?
I still think I-10 is the Mason Dixon line.
