    Agreed!

    The 2556 (a favorite of mine) actually needs a 6.3L with the Duo Prop.
    Even with a good 5.7L and the Duo Prop, the boat will scoot.
    I've installed a few Duo Props on the 2556s, it made a big difference.

    Perhaps the BIII would be an option for you.

        A portable Honda has neither of those things.
        Both are required in the US, based on what I know of European Regs they tend to be a bit more restrictive than the North American versions.
        Yes, I am in Europe. Thanks for educating a technical idiot

          Excuse my ignorance but do I have to add something to my existing starter so that it becomes ignition protected or do I have to replace it with a new specially protected one?

            No add on, replace it with a marine starter. Amazon has them at a much more reasonable price than Mercruiser.

          What would be the $$$ difference between upgrading to 6.3 with a Duo Prop and replacing the BII i currently have with a BIII?

            A LOT! In Canada I believe a factory new engine and drive would be $25k. So something to remember is that if you DO repower this boat with a new powerplant you are sort of married to it unless you're willing to take a big loss should you sell it. One local boater put $50k into a boat (two new engines and outdrives) only to buy something longer a few years later.

            Talking to the guy with 23 years of servicing boats and engines experience whom I've entrusted with the repairs of my 2556 I got assured that the transom and stringers condition can be checked without removing the engine. As for the fuel tank, when I suggested to him we do a pressure test he was absolutely against. He argued that a pressure test can make the tank leaking prematurely.

            The boat is on dry dock for the winter months and I hope to get her ready for sailing by April next year.
            I agree with both.

              If money were no object I'd rather sell the 454/Bravo II and repower with two 175 hp outboard engines much like this brave guy who had the guts to do it: https://www.thehulltruth.com/boating...st-tropez.html

                I would not do that. No way. You are giving up what is arguably the most durable heavy duty engine GM ever build for a pair of overpriced outboards that will cost 3x as much as rebuilding a 454 and after 10 years in salt are a throw away engine.
                Ive been inside a cast iron GM engine doing a partial rebuild and they are simple, cheap to repair and tough. Outboards are great if you don’t mind spending 3x as much for the same torque and don’t want to do maintenance.
                Stick with what you have.
