Whilst stripping the hull on the Range Finder Tender I needed to remove the prop shafts.

I was surprised to find they were just rods in tubes, no bearings or seals. The motors are 800's brushed.

Is this usual or a 'cheap job'?

I had this situation on an old Aerokits Crash Tender that I restored. Though there was no motor with it and the hull was in a very poor state I noticed the stern tube was plain steel with no evidence of bearings though the prop shaft was a good fit.

I got round this by lubricating the shaft with Marine Grease (Dynamite Marine) which is a blue grease that I use on my fast electrics. This can be purchased from Wheelspin Models.
You can also purchase a grease gun from them which is very useful as you can fill the whole stern tube .

On my fast electrics the flexi drive to the prop is in a nylon sleeve that is flexible but does not have bearings installed. As the brushless motor exceeds 22,000 rpm I can confirm that the grease does a good job as I have not had a failure with it.

Thanks for the Boaty. Gives me a good guide.

Does the grease cause 'drag' as I have seen this mentioned with some?
