Yes l took off the thrust washer and it's as you say a splined shaft with the end tapered out. The thrust washer is plastic with a splined metal sleeve and a thin metal washer where it contacts the rear of the prop.
If you tightened the nut to anything more than nominal torque it would damage or distort the plastic thrist washer.
The manual should really give this information.

Grease the splined shaft ,
Slide on the thrust washer,,,,, make sure it's the right way around ,
Slide on the prop,
Slip on the plane washer ,
Finger tighten the castled nut,
Then nip up the nut slightly ( about 8 th of a turn or so or until the split pin can be pushed right through ,
If you use a socket or the box socket supplied with the engine you should only need to use it in a clenched fist and normally shouldn't need to use a bar or screw driver or extension lever on it to tighten ,
Prop doesent want any forwards or backwards movement on the shaft ,,

I just looked in the owners manual and it doesent give a detailed explanation but just a parts diagram ,, suppose they want you to take it to a dealer lol.

Thanks, that's what I ended up doing after I took a look at the parts.

Yes the cavitation no longer occurs, the engine is now running very well on the boat. The splashback has been greatly reduced by raising the engine 2cm (the most it will raise without the clamps touching the ridge on the mounting plate) using a piece of wood.

Currently I'm swapping between the two propellers trying to decide which is best for this boat.
But I cannot test it at full throttle as there's a speed limit on the estuary where we are staying in Cornwall. To be honest it'll be next year before I get back to Scotland where many Lochs have no speed limit.
