Was there only one version ever made regardless of what horsepower was in front if it ??
I kno there were merc trans , C71 and C72 transmissions which were different strengths, but what about the TRS drives themselves ???? Thx

It seems there is only 1 variant. There are also left and right hand drives.

That changes how the thrust is directed from the gearsets.

The TRS uses crush washers to set up the propshaft.

The Bravo shims will fit, and using them will reduce the misalignment under load.

I believe they are also different lengths. They are not a direct swap.
