    mercuiser 888 wont idle below 1000 rpm

    So far signs are not showing a simple answer. If you hadn't said the motor was torn down and put back together, carb rebuilt I would advise to do just that. If power valve is leaking then this would cause excess fuel, but so would a mis-adjusted carb do same thing. Back fire is caused by...

    Sensor 496 HO 2007

    No, in order to find out what the beep... beep is need to connect a scanner to the motor. RINDA Not knowing what your serial number is I'm guessing as to what ECM you have. Is it several beeps, constant one beeeep, some many beeps it stops then starts again or other?

    Sensor 496 HO 2007

    It appears to be something below the manifold air temp sensor. Saying it has 3 small screws means it's not the fuel rail damper. Have a pic just a tad bit further away to get an idea what is connected to it?

    Tahoe 4.3 no Power 3400 max RPM

    2A046127 Normally the 4.3 lags behind Mercs other motors so the control system will not be the latest. Your 4.3 uses the older HSV distributor and Gen 2 cool fuel. It does list the newer PCM 112 (8M0059350) for closed cooling. I bring up the old and new because the older 4.3 used Batch firing...

    mercuiser 888 wont idle below 1000 rpm

    The motor is not burning all the fuel. Carb needs adjusted or rebuilt again, plugs not firing correctly, low compression. White smoke and head leaking, check the oil level. Might have water going in the block. The ticking is most likely a lifter, needs adjusted or collapsed

    Merc 300 Bravo slips out of cruise

    My guess Most likely cause is a bad connection, loose or corroded. Power is interrupted so the solenoid operating the shifting goes into neutral and the PCM throttles back because it's not in gear. I would start at the battery and work my way thru every connection. Turn Bat switch OFF then...
