Prop nut torque SunRise 35 25mm shaft

[pagoda]

In the process of replacing the cutless bearing my boats prop is off. Neither removing the prop nor the rubber bearing were difficult.
I have the new bearing ready and a nice clean prop.
The shaft is 25mm, the end thread I am fairly sure is M15. The taper is 10:1.
What is the correct torque for the shaft prop nut? It came off with only reasonable hand force with an 8" spanner. There is no split pin through the nut.
One descriprion I have read is to do it by hand until the prop "rings" nicely -ie it is properly on the taper??
I'd really be happier with a torque wrench setting and I would also be tempted to put a couple of spots of blue Loctite on the thread.
Does anybody have a definite make up method?
thanks,
Graeme

Hi Graeme
When intalling my Kiwi prop, they recommended 10 ft. lbs. of torque but then the nut is locked in with set screws and Loctite. Don't know if this is of any help or not
