Stan,
Here is my 2 cents about the Torque-Shift prop.
They tell you when you buy the prop that "THIS IS NOT A SURFACE PIERCING PROP" they aren't kidding. while testing his brand new prop my freind gets his boat on plane,(pulls great!!!) then feels the shift (just like you're supposed to) reaches 40...50...trims it out a little, 55...60..wow this thing looks like it's going to work great!!! 65...trim it little more and BA-BLAM oops... what was that?!!!
we stop the boat, raise the motor,and inspect the $600 investment "well at least we still have 1 blade left". It's a good thing that we were going up river.
Don't get me wrong I'm sure it's a great product. Just be carefull.
BERTRAM BOY
