Suggested source for new prop?

[Jhogan0101]

The props need to be compatible with each other 100%.
I would either overhaul the front or replace the front and rear as a pair. There are a couple props on ebay that could be useful for parts.
The parts for the threaded type are very hard to come by and many prop shops want nothing to do with them.
Treasure coast propellor has some parts and maybe able to overhaul your front prop. Good luck.
