if you run over 88mph then you will either need to run the sportmaster on the racing xs

if your boat won't run that fast then your wasting money and warranty and are better off
with the warranty of the pro xs.


Agreed. I own a 2005 Triton TR-21X with an O5 Merc 250xs and I run the gen 1 torquemaster.
