    496 Mercruiser Runs Rough Until Warm

    Hi there, just a few things to mention. By design the 496's run better on 87 vs 91 octane and have a small effect on running as it might be fouling the spark plugs IE: slightly richer running/build up on the outer transom area...Have you inspected the spark plugs for a rich condition? Clean...

    Mercruiser 7.4 mpi

    In first thoughts that one is interesting though I’m pretty sure it won’t have an effect in this situation… I believe when you get the engine started again the live data may show a oil psi reading but it won’t be in true accordance (though close) with actual oil pressure because the MEFI 3 ECM...

    2016 4.3 mercruiser efi won’t start

    Is the lanyard safety switch at the shifter up or on? It seems you’re missing 12 volt power wale up mode. Do the gauges at the helm power up? Make sure you have good connections at all the power plugs. See if you have 12 volt at the engine… Say off the back of the alternator orange wire if...

    Mercruiser 7.4 mpi

    What scan tool model did you happen to get? Are you able to see oil PSI in live data while the engine is running? (When you get it running with additive help that is) I don’t recall this engine model type utilizing an oil pressure sensor that the ECM reads and looking over the parts diagram...

    Mercruiser 7.4 mpi

    Technically you're low on fuel pressure as the regulator shows it should be 43 psi for your engine model and combined with possibly old to older fuel left in the system? might be a reason you need to help get the engine started with an additive. See your fuel regulator item number 15 here...

    Bravo 3 X upper gear timing marks missing

    Being your drive is pretty new as in year model, Service manual number 28 should be considered to old and I also believe manual number 39 is a bit old too as I believe there’s a whole newer version number or possibly an updated version of 39 that’s going to cover your drive model. As it’s been...

    Most likely a 140 or 143 degree temp… In your case though the serial number isn’t enough to help locate your exact engine model due to the age of the serial number/engine year while performing a full computer search. To help local your engine parts, we’d/you’ll need the engine model type...
