Rudder Shaft packing Size

[Azure]

Hi I have a Tiara 2008 3000 Open. I have water leaking through the rudder shaft packing nut. I need to repack with flax packing. However I do not no what size packing I will need. Packing comes in 5 different sizes. I have the manual with the steering system layout and of course no mention of the rudder shaft size Nora king nut size. Appreciate and info that may be provided to me. Thanks.

Likely 3/16 or 1/4", a call to Tiara customer service will get you the answer. This is much better than flax..  https://www.duramaxmarine.com/shaft-seal...acking.htm
