Hi there,

When last was the prop removed and has it got signed of corrosion around the brass sleeve under the nut you took off. If the prop has been removed a while ago one can persuade it with a rubber mallet by hitting it quite hard at the base of the blade, this sometimes allows it to loosen and then slide off tightly. If that does not work and the Lilly does then great. Props that have been on for long periods often result in having to be cut off. However I have found a product in S.A. called corrosion block that we apply to the top of the prop for a day or two and on regular basis tap it with the mallet and hey Presto. It a Canadian product and I am sure you guys must have it there. Use the corrosion block grease after cleaning the shaft to coat it before putting it back. Hope this helps
