    Maintenance specs-gctid809063

    I have a 2011 3.0 mercruiser tks. Doing oil change and spark plug change. Does anyone know the NGK (plug)code and the FRAM (oil filter)codes. Thanks.

      Stick with the OEM plug. Being a retired engineer, here's why I do so in my boat.

      When this engine is spec'ed out by the engineers, they try many plugs. The one they chose gave the best all around performance of all they tried. And they have a lot better test instrumentation better than we do. Moreover, if say, NGK says (whatever) is the equivalent, it may not be an exact equivalent and lack a parameter.

      A case in point. My engine calls for MR43LTS and it runs great with them. Some years back, the mercy dealer told me that merc factory bulletin said a certain NGK plug boosted performance, so I tried a set. The engine sounded like 3 cylinders went out on strike. I put the ACs back in and it ran properly. I took the plugs back and we compared them. The AC plug had nearly a3/8" inch more "reach". Reach is the distance from the seal ring to the electrodes inside the engine. Too little, the plug was firing in the threaded areas, and not firing off the air fuel mix properly.. Too much is possible to hit a piston and something breaks and rattles in the engine causing damage. The dealer was cool about it. refunded my money and gave me a set of MR43LTS.

      Point is: as said, sometime saying equivalent/better is spoken by that companies marketing group; not their engineering.

          Good day sir! I am wondering if the specs have changed from year to year. This thread is for a 2011 and I have a 3.0 from a 2007. Same plugs and filters? Thanx in advance!

        Tip:

        When changing filters (engine oil and/or fuel), use a permanent marking pen and write the date and engine hours onto the cartridge itself.

          Tip ... Spray paint the filter a few coats.
