Kipawa blades /terrova ipilot

Hey all. I've had a kipawa blade on my 80lb ipilot for a couple of years now and the thing has squeaked since about a month after I put it on. Only squeaks around 1mph or level 2 or 2.5. Hasn't bothered me much because I fish deeper water but I'm interested if anyone has seen a solution and get opinions if it might be time for a seal job. I just thought it might work itsself out but I guess my patience is gone.
The crazy thing is that when I put my stock blade on the squeak is gone.

Any ideas?

Thanx all!

Has to be prop. Check hub part that fit back at the motor. Look real close to see if you cand find a rub spot. It has to fit closer and the torque causing it to rub against housing. It could but I doubt it have enough torque to flex the shaft in front bushing causing it to squeak. I'm betting rubbing on housing.

Thanx sir! I'm gonna email em too. It's a nice prop but just a squeaker.
