I could use a little education on these terms with the Yamaha.

I understand Quietech is the term meaning they made it quieter

I understand Drive2 is a "package?" of features.

I understand EFI is electronic fuel injection.

My question is, if I buy a new(er) Yamaha gas cart as it does not use all three terms in the sales description, then I should assume it only has the features described by the terms used?

Meaning, I see a lot of Yamaha Drive2 used carts advertised. Can I assume these are NOT Quietech and do not have EFI?

And if I see one advertised as Yamaha Quietech, can I assume it does not have the Drive2 features and is carbureted? Is there such a thing as a Yamaha gas cart with Quietech that is not EFI and is not Drive2?

Does one of those terms imply the others?

TIA
