    2000 Bayliner 3055 issues-gctid825731

    Took the boat out on the weekend and it started and was running fine

    Once out of the marina I tried to get the boat on the plane and it just wouldn't get up

    The engine would not go over 30k rpm and around 20km/hr (12miles) regardless of throddle position

    At one stage the port engine actually cut off all together

    After about 15-20 min running at this speed both the speed and rpm increased and the boat ran like normal

    We have had this happen once before when we first took ownership of the boat

    Both this current time and the first time we had the problem the fuel tank had been on empty and we had just refilled the tank before heading out

    Ive called the mechanic to get him to have a look just wondering if any one has any idea of what it could be ??

    Boat is a 2000 3055 with mercs

    Thanks in advance

      Did you check the bilge before heading out? 12" of water down there would create same problem until bilge pump emptied it, assuming bilge pump is not wired for automatic discharge while tied to the dock...

        is the fuel filter some thing that a novice can change or better to let my mechanic do it ??

        The bilge pump is wired to auto and will pump out when ever it detects any water, our dock is powered so boat is always connected to power

          You should be able to check and replace the fuel filters - just remember you are dealing with fuel!! (BOOM!) ... When you remove, be careful not to spill the fuel out, tip the contents into an ice cream container (white is preferable) and check for water etc. You can get replacements from pretty much any chandlery (Whitworths in Townsville???) I am pretty paranoid about fuel condition so I have also added second filters on my bulkhead above the pickups. If you do this, don't use glass filters designed for diesel or outboards, use the same ones as you have on the motors - once again I got the assembles from Whitties... https://www.whitworths.com.au/main_i...AbsolutePage=1

          Good luck.

            You could try the fuel filters but I'm not convinced that's the cause. Could be the water seperators too but that's a guess. could also be an ignition problem.

              The Mercruiser fuel filter also acts as a water separator. It does sound like either water or crude in the fuel. Replace the filters and pour the old contents into a glass jar after it settles you will know if there is water in it.

                thanks guys i will replace the filters and inspect the contents.

                When installing the new filters do they need to be primed with fresh fuel before installing ?

                  I never had to with mine. You probably have an electric fuel pump, bump the starter and it should run for a minute or so then stop. The filter is full at that point as well as the carburetor.

                    No need to prime - but remember, the electric fuel pump is wired into the oil pressure switch so will only start pumping fuel when it sees oil pressure - generally after a couple of seconds of cranking. You prob have enough fuel in the float bowls to start anyway...

                      The starter soleniod provides power to the fuel pump when cranking and once started the oil pressure switch provides power.

                        My first thought was fuel filter/separator as well, especially if you ran the tank to almost empty. Any grunge on the tank bottom could now be picked up and trapped in the filter, plugging it's flow. I'd follow the recommendations above including checking the removed filter fuel for contamination. Good Luck.

                          Thanks guys

                          will grab some filters and switch them out this week.

                          Probably a good idea to keep some spares in the boat

                          Thanks again

                            Sounds like water in the fuel system to me. My pal had this similar problem and had to remove his filters several times to dump out all the water. Good luck. Griff

                              my mechanic was at the marina yesterday so he jumped on and installed the new filters.

                              He also believes that running the tank so low was the cause of the issues.

                              I will change the filters every few outings to make sure there is nothing still clogging up the system

                              Also going to look at installing another set of filters like Oz suggested

                              will be on the water this weekend to test
