Just acquired a lovely Clyde puffer, runs ok has a car blower motor fitted. Id like to remove the prop and inspect the shaft but haven’t a clue how to. I can’t see how you would get the prop off.

With disassembling the stern post, I am guessing that removing the motor and pulling the shaft out forward, into the hull, would do the trick. Hopefully, the shaft is not so long as to require further disassembly.

The motor has been glued in place rather then using a bracket

[Darren007]

Is there a way to remove the prop without removing the motor? Would it be a case of holding the shaft and unscrewing the prop?

[JimG]

From the notch in the stern post it loooks like there will be enough clearance to remove the prop from the shaft. You would need to rotate the shaft, not the prop while unscrewing the prop as it looks like the prop blades wouldn't pass the stern post.

Would the m4 nut just behind the prop need to come off first?

If it aint broke,  dont fix it!

  Could be tricky getting at the shaft, is the ply cover over the motor removable? If it is good, you need to access the coupling from the prop shaft to the motor shaft and preferably remove the motor and mount it properly (why on earth would you glue in a motor?) so that you have access in the future for maintenance. Once you have the motor and hopefully the ply cover out you should be able to see all the connections on the prop shaft/motor, normally on a 4mm shaft there will be a nut locking the propeller to the shaft outside the hull then another nut on the motor end of the shaft inside the hull then the coupling to the motor. To withdraw the prop shaft into the hull you will need to remove both the motor and the coupling and have taken off the propeller.
    Hope this helps and if you email me I'll send you some pics to show you how I set up props/shafts etc.
              Good luck,
                    Regards, Pete.

I knew I was right collecting all those car heater, w/screen wiper and door window motors....


Text sugg ests a picture is included in the posting ?

[Rich griff]

Ah, I see them now....


Maybe let sleeping dog lie else quite a bit of work needed...


As long as the shaft turns freely and is lubricated, let it be perhaps.


What's the rest of the boat like ?

that looks like a grub screw on the boss of the prop, it is one way of securing the prop until you want it off as the grub screw tends to flatten the threads somewhat making it a bit of a job. nemesis
