    2005 Mercury 50hp 2 cycle surging under power

    maybe one option would be to unplug the air line and see if it's actually working with or without it. Keep removing suspect parts/functions in and out of the equation.

    2005 Mercury 50hp 2 cycle surging under power

    I wonder if the fuel pump is not actually running, i.e is the air line to it actually moving the diagraphm. I have no idea what typically fails on these types of motors, but I would start with fuel obstructions (assuming you've already confirmed the rebuilt carbs are good) and then move on to...

    2005 Mercury 50hp 2 cycle surging under power

    Is it misfiring or just erratic speed? What about the airline to the fuel pump?

    2005 90hp 2 stroke cdm wires are wrong?

    it runs, but backfires. I was 99.9999% confident this is right, but the engine failing to maintain speed (plus these older manuals) were sending me down a rabbit hole of options. I'm thinking now being hard to start, the engine struggling at higher RPMs makes me think perhaps I'm having issues...

    2005 90hp 2 stroke cdm wires are wrong?

    Thanks! I have not been able to find this info post 1993 and 132 seemed to be very common. I think you're saying it should be fine because the wiring likely didn't change with firing order? I.e. white used to be 2, but now is 3? I think to verify this, I'd still have to ensure the trigger...

    Motor has no power under load

    Wondering, did they have a power supply hooked up on land? That would be one key difference vs in your boat with just your battery.

    2005 90hp 2 stroke cdm wires are wrong?

    I replaced a cdm module. I looked up the owners manual and it says the brown trigger wire 4pin should be on the bottom, white in middle and our please on top. So does the install instructions for the harness from CDI. Mine has the white on bottom and brown in middle. Does anyone else...
