69W-W0093-10-00 Carb kit

The Yamaha Repair kits parts catalog fo 69W-W0093-10-00 Carb kit show QTY 1 for this item but The price seams way too high to not cover all four carbs on a 60 4 stroke.
Can anyone tell me if I need 1 or 4 of them?

That is single carb kit, you would need 1 kit per carb.

***, Thanks.
