I tried to unscrew my fin mast from my TI's V2 drive. I sprayed RP7 into the brass insert but when I tried to unscrew the mast I found that instead of the mast coming loose, the brass insert started to rotate in the sprocket shaft. My drive is less than 2 years old.
This was the second fin mast I was trying to remove. The first unscrewed as described in your maintenance instructions on this forum - albeit with some initial effort to overcome the loctite.
I am now worried that this drive will fail when I am out at sea.
What can be done about it?
