2017 F25LWTC - How often is the VST changed?

[SoCalAngler]

I recently serviced my outboard including:
Water pump kit
Spark Plugs
Engine oil and filter
Gear oil
Fuel filter
Added a Yamaha 10 micron external filter/housing (mini 10)
Is the VST something that is change after so many hours? I could not find a maintennace schedule for this motor.

Thanks

I don’t do any maintenance on my VST(Suzuki) other than fresh clean ethanol free fuel. Mine sits for 7 months of winter and I make sure the residual fuel is stabilized.
