2001 Optimax 200hp Prop torque???

[bobsquatch]

Tried this in Bass Cat Boat forum but thought might get correct answer here? Changing props temporarily on a 2001 Pantera III with 200hp Optimax from a 25" Tempest+ to tryout a 23" Fury prop - hole shot has been pretty slow and bow really kicks up high. Have changed out pvs plugs a number of different ways as well as several ptp changes over last several weeks. Better now than it has been though out of the hole still slow so want to see what the Fury would be like? I've seen online videos changing props showing 55# as correct torque when tightening nut down? I had an 02 Classic with same motor for 8 yrs, changed props a number of different times and used 100# torque after checking with "someone", can't remember who though? Took Tempest+ off, have Fury on but waiting to torque down until reasonably certain of proper torque rating. Hub kit is Flo Torque II I believe with the 2 piece "rubber" inserts. Thanks

If using the twp piece rubber insert it 100 ft lb.

I am using the 2 piece rubber insert, always have. Also just got answer back from Bass Cat Boats and they indicate their rigging crew torque all props at 100#.

I hope this is NOT true...….Some prop hub kits only require 55 lb-ft.

[bobsquatch]

Agree but BCB's may use only hub kits with recommended 100# torque ratings?

99.99% of Basscat boats run Fury props. The ones that don’t Trophy or Tempest...all require 100ftlbs

Proper prop torque specification depends on the Hub Kit being used, not which square bore prop is being used.

Many props are used with different hub kits due to the propshaft size (or gearcase type), meaning the torque would be different.
