    3.0 intake interchangeablultu

    Hey guys, got an update and question. For a backyard mechanic kinda guy, I have determined that the 140 in my 76 Silverline is saveable. As far as intakes go, are they interchangeable? As in, can you take an intake off a newer 3.0 that’s got the large base carb and bolt up to my motor? Just...

    Kinda figured so I’m gonna drain oil and leave drain plug out and then run water through where the thermostat lives and see if any water comes out oil pan drain plug hole. Also contemplating dropping oil pan for a visual inspection.

    3.0L comparability

    I was hoping to be able to use my existing bell housing and coupler on the new motor so I didn’t have to redo the entire drive. That’s why I was asking about interchangeability

    3.0L comparability

    Hey guys, so I’m in search of some compatibility info. As you all know, my sons and I picked up a 1976 Silverline tri-hull boat that’s got a mercruiser 140 in it. I have since found that the block has sat with water in it and the exterior of the block up in behind the intake has cracked. My...

    1976 mercruiser 140 carb

    Minkota autopilot

    I have a minkota autopilot 24v and the autopilot switch has gone on the fritz. Is there any way to hardwire it and bypass the rocker switch?

    1976 mercruiser 140 carb

    The inside of the carb is pitted up real bad and there still white powdery crusty crap in carb I can’t get out of passages but can see. Just feel it’s a better option to get a different carb. Here are photos of the outdrive.

    1976 mercruiser 140 carb

    Hey guys. I picked up a 1976 Silverline Comoro 17T boat with a 4 cylinder 140 hp mercruiser in it and I’m in need of a carb. The small base Rochester 2gc that’s on it is trashed. Any budget conscious options that you guys know of? I’m ok with a used one as long as it’s not trashed. Found a...
