Good evening. Would it be possible to tell me what lower this motor left the factory with, by serial number?
Thanks.

My 2001 xb came with the torque master lower unit

[JOE54]

all xb engines had torque masters to my knowledge

[jusmangrum]

Do all torque masters come with the big shaft?

[JOE54]

no sir they did not in early ones had 1 in high carbon steel shafts

[jusmangrum]

I have an XB but have no clue what lower I have. But I do know it’s a small shaft and I was under the impression that all torque masters have the fat shafts

[JOE54]

no sir the early ones did not

As Joe indicated, the ProXB came with the early Gen-1 TM Gearcase, which had a 1" Diameter Propshaft.

1.25" Propshafts started showing up in the 2004 calendar year.

Thanks don. That would explain it.

[drdriver]

Thanks, guys. Much appreciated
