ok cheers i'll try in the morning

:D well its morning here and its stopped raining........

so, when engine rotated in normal direction of rotation, which way does the impellor turn??

use some logic........impellor will act like a water brake....

in so much that the water will try and stop the impellor turning........

and if the thread is the wrong way will try and undo the impellor........

did you check cmsnl.....is the impellor "keyed" to its drive shaft?

If it's the same as an NS125 it's just a normal right hand thread.I found it best to use a 12 volt impact driver to remove and fit it without turning anything else.
