Tru-Turn makes an adapter for the Saito 91 that uses a lock nut the Saito requires. If you go to the Tru-Turn website and look up the adapter for the Saito 91 you will see what it looks like. I think it's $14, kinda steep IMO.

I am not sure if the Saito 91 has the same thing as the 72. For the 72 you have to put in a 1/2 inch recess for the adapter. Please be aware that I am not even in the same league as MinnFlyer with my drawing but I think you will get the idea.

I agree with beach, it looks to me like the prop has to be reamed out to accommodate the locknut. Hard to say without having the pieces to examine.

Here is a picture of the adapter that Tru-Turn sells for the Saito 91.

I saw your pic and I donīt understand if it uses both nuts that the engine have first and the adapter next, or something else!
Can you explain me please?

Thanks.

Below is the content on an email I received from a "Ric" at TruTurn. (I have a Saito 91 and a new Saito 150) HIS QUOTE NEXT: Yes, if you have a saito .91 or an Older style 120,150 or 180, then you will need to run a short shaft double jam nut
adapter kit.
Our short shaft double jam nut adapter kit requires a 1/2" hole to be reamed into the FACE of the prop. This is to allow our primary nut to pass through the prop washer and into the prop in order to make up for the short crankshaft
on these motors.
To our knowledge, the .91 still comes with a short crank, but the 150-180 all changed in 2000. The 120 changed to a longer shaft this year and
NEW 120-180 saito's won't need the 1/2" reamed hole in the prop. You'll use the TT-0823-A adapter kit for them. Here's
a link

NOTE: THE ONLY LINK THAT MAY BE ACTIVE IS THE ONE TO THE .91 ADAPTER.
I ended up buying a cheaper brand for my .91, but bought the TruTurn for my 1.50. (I had the machine work done to the backplate bore.
I hope this helps.......lownslo
