    Carb to MPI problem 2011 Merc 4.3

    Thank you for your help. My new Cap and rotor should be here tomorrow. Will install and give it a try. Crossing my fingers this is the fix. Do you think any of the fuel injectors are bad?

    Carb to MPI problem 2011 Merc 4.3

    The problem is starts great , idle is good, all gauges good. Runs great at lower rpms, start putting a load on her and she starts to sputter and backfires a little and then starts to smooth out a little, but you can still fell her struggling. 2011 Tahoe Q51 4.3 Merc Mercrusier MPI Alpha 1 1A035000

    Carb to MPI problem 2011 Merc 4.3

    Thank you, Scott, for your help here. I appreciate your time. I will buy a cap and rotor and see. Is changing the injectors out for new ones something a person could do themselves?

    No kidding. So it’s injectors? This sounds like not a good thing. Could it be the cap causing the rough running at higher rpm’s?

    Carb to MPI problem 2011 Merc 4.3

    So I’m a rookie at this but I can figure things out. The pump circuit is part of the carb? I know stupid question. Do you think a rebuild on the carb could help? Everything else is good. All gauges etc…. Thank you for taking time to help me out. I really appreciate it.

    Carb to MPI problem 2011 Merc 4.3

    Hi Scott, I hope rebuilding the carb will help. It idle fine and when you give it some gas it runs rough and then smooths out. I’ve changed Fuel filter, new plugs and wires, new fuel pickup value. So I think it’s the carb issue.

    2011 4.3 Alpha MerCruiser winterizing question

    Is it possible to put some air in it and blow the water out like you do for an RV? Would that hurt things. Maybe keep the plugs out and take it for a spin around the block to move any water left out? I know how to change the oil and lower unit. Just wasn’t 100% on getting the water out...

    2011 4.3 Alpha MerCruiser winterizing question

    Ok. So I will open this one single handle deal and take out the 5 drain plugs. If I take the 2 front hoses off one on each side and pour some RV antifreeze I should be good to go?
