    Code reader help 4.3 M.P.I.

    No, sorry, that trick won’t work on your 555 ECM… There’s also a rental program on eBay to rent a Diacom so you could check things out for yourself if you don’t want to buy a marine scanner tool like mentioned above...

    Mercruiser 350 MAG MPI MIE SKI 0L305632 skipping

    Just a quick reference point in regards to this design cap didn't really start until very late 2002 but considered 03 year model for the Merc marine side...VP too I do believe. The serial number suggests this will be the distributor ignition sensor design...

    Mercruiser 350 MAG MPI MIE SKI 0L305632 skipping

    Are you getting any warning horns associated with the skipping? Any of the other gauges skip as well? Make sure all wiring connection points are clean and tight. Doing this hot or cold? or both? X 2 on timing light testing too. You may want to connect a fuel pressure gauge to the fuel rail...

    1985 4.3l v6 mercruiser piston rings

    Sorry, possibly my mistake. The number you gave was a engine block casting number and from searching that number out seems to indicate the engine you have was used in 1987... Your 1985 engine block "may" had been changed out at some point. My first thought was to confirm the year of your...

    SEI preload and a stern jack

    Either way it may have to come back apart but it's been a while of physically doing this for me, but I believe there is a process defined as false preload reading before the nut gets any real torqued down in which sounds as if hasn't happened yet? Basically near finger tight still? You'd need...

    O2 Sensor codes . . .

    Sorry Ted, but seems about the only thing I can suggest here is go buy a book (another service manual in your case) and join your admiral in the sun. 🌞 🙂 Some general info regarding the health of the catalyst exhadust...

    Bellows ground wires cut SX-A

    Tough one to be exact in explanation for the Volvo as there isn't/doesn't seem to be a direct guide for the grounding/bonding corrosion protecting system like merc offers in their service manuals. To get a visual of it outside of having one near by, you'd need to keep studying the schematics...

    What is this filter on the ignition power wire?

    It’s often referenced as a noise filter. There are times when it falls, the engine may not start/run but that condition is intermittent. You’re able to buy a new harness from Merc using your serial number to help ensure the correct part number for about $87.00. Example is item number 17...

    Your next option to try is contacting MerCruiser Customer Assistance either by phone or their website explaining the situation in the note section of the following link that the serial numbers are correct for diesels but they are coming up as petrols in parts look up catalogs here the USA and...

    Mercruiser d4.2 220 turbo AC - when they were built ?

    When you get a chance, try double checking these two numbers… The first one 0L667048 doesn’t come up as anything known but playing and comparing it to the second number posted, it appears the second 6 should be a 0 so 0L607*** for both. Problem is both numbers come up as 5.7L gas engines and...
