3.0LX - Mercarb to Rochester ?

[Rake722]

Hi all
I’m thinking of buying a Rochester 2 bbl as a spare carb due to the boat being in a remote location.

I’m told by the vendor that it’s a direct replacement.

Is that true ?
is my idea sound or am I asking for any trouble ?

many thanks

Not a direct swap

Thanks Scott. What has to be done for it to fit ? The seller said they’d supply it with the correct fuel inlet so the pipe doesn’t need to be bent.

rochesters havent been used on 3.0 since 1990

they re-designed the motor in 1991

while the carbs are similar, they are not the same

I would simply keep your fuel system clean
