Twin disc and QSM11

[Zane Andrews]

Good evening, I am in the process of powering a boat with a qsm11, currently the boat has a man D2876LE401 with a twin disc MG514c gear. Was wondering if there is a bell housing to join the twin disc with the qsm11?

Your MAN engine probably has the same SAE specs as the QSM11–SAE 1 & SAE 14″ for the bell housing & flywheel–Should be “Plug & Play”   BTW—–The Twin Disc MG514C  is a very good gear –kinda like they do not make them that good anymore     

 

Caution though– The QSM 11 is most likely less engine that the MAN so you will need to prop down to where the QSM11 is at or below 20 GPM at 2000 RPM cruise with the vessel fully loaded.
