Drive Question. Please Help
 

Hey guys. My Uncle had some kind of speed boat that he gave me, but after getting it i realized i don't have the time or money to fix it up. I'm trying to figure out how much the drive is worth because i'm moving soon and need to clean out my yard. I can't seem to find info on it anywhere. I am also selling the 454 Big Block and transmission and prop that is attatched to it.

On the drive, it says:

Arneson TM Drive
By Borg-Warner
Model 17-21-003
MFG. By Warner Gear DlV., Muncie, in USA

If anyone has any information please help me out here, I can't find this model anywhere.
