How do you remove a duoprop inner prop

"After you have removed the af

"After you have removed the aft prop, put a piece of wood between the cavitation plate and the propeller blade. Then remove the locking tabs to to release the spanner nut; then remove the nut, the plastic washer and the locking tab washer.

This is well-explained in the Seloc manual, which I think people should consult before doing their own maintenance/repairs."
 
"In your first post, you said

"In your first post, you said the manual was not clear on prop removal. If the nut and lock tab have been removed and the prop does not slide easily off of the shaft, then the problem is probably that the prop has become stuck to the shaft due to the onset of corrosion. This is quite common and has happened to me. To remove the prop, you'll have to use a propane torch to heat the prop and melt the rubber around the prop hub. This can be tricky and if you're not careful you can damage your prop shaft seals. What I did is I had a "prop puller" manufactured by a friend who is a welder. Using the heat and prop puller you should be able to remove the prop but unfortunately in most cases, the hub will remain stuck to the shaft. To fix this, use a 4 0r 4.5 inch grinder to cut the hub lengthwise, pry the cut apart and remove the hub, being careful not to damage the prop shaft. Using the puller along with the heat made the job much easier. The prop will undoubtedly need to be re-hubbed, but the prop will come off if done with care and patience. The answer to preventing the prop from being stuck to the shaft in the future is to grease the prop shafts really well with Volvo Penta prop grease which works much better than anti-sieze compound per the SELOC manual. I hope this has been of some help. BZ"
 
"I had this problem last year.

"I had this problem last year. I read all the posts on this subject and decided to try some things before destroying the prop. I tilted the drive up at a 45 degree angle and applied liquid wrench between the hub and shaft. I let it sit for a few days. That alone didn't work. I eventually poured hot (boiling) water onto the hub as I hit a block of wood that I pressed against the blade with a dead blow hammer. I placed the block near the hub where the blade is strongest. It took awhile, but I got it off without damaging the prop. This year I put the prop on myself and used the VP grease. Today I removed the prop for the season and it slid right off. Hope this helps!"
