Interchanging mercruiser carburetors.

[rolmops]

Does anybody know whether the mid eighties carburetors of the 140 and the 165 mercruiser engines are inter-changable?
thanks,Cornelis.

Don't know if this helps but I used a carburetor off a '77 470 on my '84 140.
Basically I replaced the Mercarb with the older Rochester.

I'll make a guess here and say if both are 2bbl carburetors, you should be able to swap them with little to no modification.

Thank you for answering so fast Bondo
They look exactly the same,but they have different numbers.
The 165 bowl is #1389 99564
The 140 bowl is #1389 98490
I used a 165 carb on my 140 for the last 2 years and it did fine but I also have 2 140 carbs in my junk pile. One a Rochester,the other a mercruiser.
Hank from L&M in Port Bay (I presume you know him) thinks that there is very little difference.
