WTB: Spare prop for Yamaha 200 HPDI

[Monaro21]

Anyone know of a good spot to pick up a spare prop for a 2004 Yamaha HPDI outboard? I have a nice stainless steel one on there now but I feel like I should be carrying a spare (not stainless steel) just in case something goes sideways one day. I am not looking to spend too much so any ideas would be great.

I live in Victoria.

Thanks!
