    2556 Ciera Sunbridge-gctid715115

    Hi folks, I'm a newbie and hope I can help Bayliner lovers and get help regarding my 1993 2556 diesel Bayliner.

    I'm hoping with my first post that someone could advise me on prop size. I currently have a Bravo 2 leg running an 18 3/4" diameter prop with a pitch of 17". I'm not reaching WOT revs and can only get a top speed of 16 knots on a good day. My engine is a Mercruiser D219 putting out about 180 horses.

    Any info would be most grateful.

        You won't get much help, since 99.9999% of those boats are gas, and nearly all of them over here are gas. I don't think this was a factory offering, so yours would have been swapped.

            Love the boat, but that is the most unique power package I've heard of on the 2556.

                Assuming the boat bottom is clean, how shy are you of max WOT rpm? I believe the Bravo 2 can take up to a 20" diameter prop. You want to decrease pitch by 1 inch for every 200 rpm you're shy. Give us more info, and welcome to the BOC!

                  This video shows the same engine in a 2556, and it looks like he is getting 23 knots? Maybe you could find out from the owner of the YouTube video what setup he was running. He mentioned he was selling the motor in his comments.

                    I would start by checking the gear ratio on that B2...

                      Welcome to the forum!!

                      As others have stated, lets start with as much info as possible.

                      What is the max rpm of your engine?

                      What rpm are you able to reach now?

                      What is your gear ratio?

                      Is the bottom clean?

                        Sorry for the delay in getting back to you but I've just got my boat out the water to find out the gear ratio which is 2.20:1

                        My engine should be able to sit at 3600rpm but I'm lucky to achieve 3200 and my top speed is 16 knots.

                        The bottom is totally clean and the engine I'm pretty sure is putting out lots of horses.

                        Any help in fitting a better prop would be great, I would be as sick as a dog if I spent £500 on one that didn't perform any better than the current one.

                        Thanks again - Mr McClown

                          I think I've the same boat with the same engine. Has anybody a PDF about this lovely boat and about this engine?
