I've broken a prop and decided to change all of them cuz they are beat up and out of balance at best but the dang things are stuck I got the broke one off but I feel like I'm gonna break something with all my prying and rocking and suggestions I think it's a 1 mil shaft the props just push on any I ideas tips or tricks was thinking of trying a drop off wd40 right on top where you can see the shaft or a drop off water etc then let out set for a while I've read cut them off but I'm not 100 percent sure I have a tool small enough for the job
