Unscrew the Allen Screw in the hub, aware that there are two in each hole one on top of the other. Once removed, the blade pins should easily push out. Unscrew the nut, warm up the hub with a hairdryer (the bronze will expand), hereafter use a puller with two legs to remove the propeller.
Follow the same procedure as with shaft propeller, but without use of hairdryer or the puller. Once blades are off, and nut unscrewed the hub is easily removed.
Firstly, please note the blades remain in place throughout. Use a screwdriver to remove the old stops, twist the new ones in place, which can be a little tricky, tap in place. DO NOT remove the blades!

If the hub part needs to be removed, use the puller which came with the propeller.

Propspeed leaves a silicone like surface, and possible growth is easily rinsed off.
If the propeller is to stay on, it should be cleaned. When bronze come out of the water into the atmosphere its oxides, and blades may get stuck. To prevent this, apply grease to the gears and gear wheel (on the 3 blade).
