Hi, I am a new member and don't even have a boat. I joined to try to get an answer about propeller mounting. I have a machine shop and a customer asked me to bore out the mounting taper in 2 brass 4 blade props which will replace the existing severely worn out ones. The old ones are 21", these are 22", but bores are smaller, so, he wants me to bore them to size to fit the propshaft.
After boring them out, the keyway will have to be cut. The keys that came out with the old props appear to me to need replacing. They are brass.
They have a groove in the middle of each side running the length of the key.
Are they made this way? If so, for what purpose? I am no expert on drive keys on propellers, but, I would think they should be solid square section to seal out water.
I don't know the availability of the keys, so, I might have to make them, and want to be sure to do it correctly. I think this is a good place to get advice on this subject and I greatly appreciate any help.
Thanks.
