Name this prop
 
Here's a challenge: Can anyone tell me the make/model of this 3-blade bronze feathering prop?? The probe out the front is the greasing line. The conical anode isn't shown.

Reason: I need to find out how to take it off..

Thanks,
Cameron

You got me on the brand. Those nuts on the case halves are probably a give away to someone, but I've not seen them. Max-props have hex head bolts into tapped holes, not nuts.

Anyway, I suspect it disassembles similarly. Remove whatever is in those recessed slots at the rear of the prop. It should allow a cap to come off that is holding the blades on. Then, those nuts must be keeping the case halves held together around the shaft.

If you are planning to replace it and it's working fine, be sure to note any indicators on the gears, so you can get it back the way you found it. On the Max-prop, there are two separate settings and they are critical, each identified by a where a letter on the gear or case, lines up with a score or dimple when feathered. You would have to be very careful that it didn't just fall apart, before you cleaned the grease out to find these.

Start soaking the nuts with a 50% ATF and 50% acetone mix in the meantime.

Can't be an Autostream if it's bronze. Autostream props are stainless.

Older models were either bronze or stainless. The designs were slightly different and you had to get the right anode for whatever particular model you had.

The nuts secure the pitch adjustment screws and have nothing to do with the removal of the prop.

Here is a link to installation instructions for all of the discontinued Autostream models:

Wow!! Thanks, Fst.. It does look like it's a Seahawk 6000. :) :)

The prop is a few years old now and is in excellent condition. Love it! Everyone should have one. I had originally thought it was a Seahawk but, like Windward, thought they only manufactured in stainless. The stuff you learn on Sailnet. :rolleyes:

I need to take it off to get at the stern-tube and then put it back on again afterwards. Have downloaded the instructions from the link you posted and it all makes sense, although dislodging the crustaceans after years of residence to get at those tiny hex screws will be interesting...

Right there is a good reason to read the instructions first - because I would have waded in and stuffed the lot!.. :eek:


Thanks all for your input. :)

Cheers,
Cameron
