Securing prop shaft adaptor
How do I secure the prop adaptor to my '94 blade engine?
I have the retaining bolt, but I need some form of spacer/washer to sit underneath it and bear against the adaptor.
I've had a look in my 'blade manual and there's a photo of the engine sprocket with its bolt and retaining washer.
Would this washer be suitable to use on the prop adaptor and does anyone know if they're readily available from a Honda dealership?
What have others used?
Andy.

You really need a small spacer washer turned up that will sit behind the prop flange, ie put spacer on first, then flange, then tighten up the
retaining bolt against the prop flange. The flange needs to be just thick enough so the retaining bolt clamps up against the flange and not the output
shaft.

I'd still need some sort of large retaining washer though, Chris, as the bolt head is smaller than the diameter of the hole in middle of
adaptor (see pic).
Anyone got a suitable spacer that Chris mentions?

Ah I see what you mean now. I can't remember now how the stock blade one was, it must have had a bloomin great thick washer on that bolt. Either
way though, you still need to take up any slack so the flange cant slide on the splines.

Washer
I believe that the washer used on the rear sierra hubs are not far away. The thickness has been mentioned on the Forum some time ago. David

Sprocket bolts usually have a splined tab washer behind them which you bend over to stop the bolt coming loose.

I'm surprised at that...I've just been into my local Honda dealership and they had the sprocket retaining washer on their parts
microfiche. Just over £3.
Had to order it, mind, as it wasn't in stock. Should be here in a week's time!! Good Job I'm not in a major hurry for it then!
Still, one bonus was that they did the fittings for Goodridge hoses and so I was able to get the correct length banjo bolts I've been after for
my rear (Sierra) calipers! 
They also do a nice line in aftermarket diddy indicators (E-marked an' all) so that's another item I can tick off the parts wanted
list...

i tried to get a cupped washer made to go between the adaptor and retaining bolt but it couldnt be made easily so on the advise of colin at mac#1 used
this washer behind the adaptor instead.
its 4mm thick, has an internal diameter of 32mm an an outside diameter of 55mm and does the job perfect and can be bought from most nut an bolt
suppliers.
i got a load free from walters hexagon if that helps
