WTB Carburetor for 85hp sportster model

[ocod]

^as title states looking for carb for boat considering buying.

So if you got one lying around or if your local and can let me borrow it for the sea trial that would be great.
Guy is selling boat for 3800 bucks and I'm sure I could get it for less but I need carb to test other motor.
Otherwise I'll have to run ea motor w/same carb in sea trial

Thanks
