Any problems not draining VST?

[tidelee10]

I have read the Yamaha manual for winterization.....drain VST...I heard someone say "if the fuel is treated just leave it full"...I would worry about water freezing up in the VST if for some odd reason there was water in it. What is your opinion? Anyone have any problems leaving it full? btw I did a search on this topic and didn't turn up much........Thanks!

I run the fuel system on the fogging mix that Volvo and mercruiser recommend when winterizing efi outboards.

If you think there is a possibility of water in VST then it is best to drain it, but then I would follow Rodbolts advice of treating the fuel and running till it is though the system as he does this stuff for a living

I thought he was joking around... has Volvo or mercruiser ever made an efi outboard?... I know rodbolt is the expert...I have learned a bunch from you all...thanks!
Happy holidays

EFI is EFI be it outboard or not
Just my thought
