Can I reuse prop bush

I bent a prop 150m off the beach in Muscat in 13 feet of water. Hit some concrete that was probably washed out of a wadi in the cyclone in 2007. Prop is on Johnson 105 Commercial, year 2000, prop Part no 391201, 14 1/2" x 19". Diagram on BRP Parts website. Pic doesn't show how badly the top right prop blade is bent.

I may be able to get a prop in Abu Dhabi at the weekend but cannot get the splined/rubber bush that goes inside. Prop is twice the price of same from USA but I need to be back in the water asap.

My question is can i remove the bush from the old prop and re-use it on a temporary basis unti lI can get the right parts from UK/USA. I guess this bad practice but may keep me on the water while I wait.

Also should I replace thrust bushing and prop nut spacers as a matter of course?

I am also hoping no damage to gearcase or driveshaft. Any advice welcome.

Should be no problem to re-use the prop bush if its not torn the rubber and you can separate it from the prop. Thrust washers etc should be fine too.

Thanks Martini

This prop is beyond repair due to pitting corrosion that has weakened it as well as the bent/torn blades. Therefore I am not too concerned about damaging it. However as I have never removed a bush before I am guessing that the prop should be heated to expand it first, perhaps with rags and boiling water? and then the bush pressed or pulled out? I would be grateful for advice if this is the right method and whether I should try to lubricate the old bush before trying to remove from the old / re-insert it in the new prop?

I have found a prop for sale in Abu Dhabi and hope the dealer will be able to swap the bushes for me but need to cover my bases in case I need to do it myself as there re no bushes available in UAE if I stuff it up,

Many thanks again
