Default Speedmaster Tranny Question

can you use a 72c transmission? What would the difference between the TRS and Speedmaster be?

Thanks again OSO for putting up with all my newbie questions...

What is your application? What kind of drive do you have? Do you use a drive shaft or is your transmission "plugged in" to the transom housing?

The Merc TRS transmission is not the same as the Warner 72C.

The 72c is longer {I think 1" ?}....Speedmasters {3a & 5} were rated for 750 hp...TRS 525hp...Much stronger.
If you have TRS...Look at Konrad drive & Huber HM800 trans.{71c case}

I have a project in the works and just curious to the differences. Mainly the tailstock and input shaft differences in the drive to tranny.

You just need an SSM tailstock for a plugin. The TRS tailstock unbolts and the SSM replaces it.
