All the prop-shaft tubes that i have used are all bought ready made, I have noticed that it doesn't matter how long i spend aligning it i always think that they are still noisy should i fill the tube with some sort of grease ??

              Yes

Not much else I can say.

Grease the prop shaft.

Remove shaft from tube, squeeze the grease into the tube from the outer end
.
Put your finger over the inside end of tube and  slowly push in the prop shaft.

When the prop shaft is in wipe off excess grease.

Do not attempt to put to much grease in as this will strain the motor and lead to other problems

When finished, the motor should still run about the same speed.

Tube of this will last years. Excellent firm and service.

If the noise is coming from the shaft, probably.  If the bearings were unlubed, it will help. 
If its a clonking noise coming from the coupler, no.  That will need a look at MMB for one of his silent rubber ones.

Hi para_handy
You have to grease the prop shaft as 1. it helps stop water geting up their 2. it lubs the bearings.
I use white grease from halfords. Hope this helps!!

Hi para-handy, is there a washer in-between the end of the bush and the prop locking nut.
If not, that could be your problem.

As already stated, grease the shaft and I also put a small amount on the universal drive shaft coupler.    I use a syringe ( less the sharp bit ) fill it up with the grease and pump it into the shaft.


Hope this helps

Hi I agree with John44, I was using standard U/Js and spent an afternoon chasing noise and it was the slight mis-alignment of the nut locking the u/j to the prop shaft, a few washers cured it.

Have you used Ron Dean's lubrication mix?  one part of each, WD40, 3 in 1 oil and vaseline.  Well mixed and almost frictionless.
