  • '03 X10 issue (please help!!!)

    Hello all,

    My Dad was out in our 2003 X10 about a week ago, and the boat stopped working. It had to be towed into the dock, and has been at our mechanics place since then. Our mechanic has been working on boats all his life, but doesn't work with very many Mastercrafts. To sum it all up, he doesn't know what is wrong.

    He originally thought the fuel pump needed replacing, went ahead and bought a new fuel pump, and installed it to no avail.

    He contacted our local Mastercraft dealership locally near Vancouver, BC, but they can't even diagnose the issue until July 11th at the earliest. Terrible news obviously...

    Here is what our boat mechanic just told me over the phone (main issues):

    - 0 fuel pressure
    - The boat is not getting fuel...and the new fuel pump installed didn't help
    - The dash is "flat" and not registering on any of the gauges
    - He thinks it may be an electrical issue, but isn't sure

    Any thoughts/suggestions? I am going to forward on any responses to our mechanic, in the hopes that he can diagnose the issue a lot earlier than July 11th...thanks for your time!

    Elect fuse/breaker on the + wire going to the ignitionkey/dash functions?
    Does the fuel pump come on when turning the key on to pressure up or not? If not he should have never replaced the pump if it's not getting power. If it is getting power and triggering the pump with 0 pressure build, then new pump is bad.
    Guages on my 06 are stepper motor and will cycle once key on and then go dead until the engine starts. My 96 had old elect potentiometer ?? guages. Again nothing except maybe the volt guage and gas guage is going to register until the engine is running.
    Need more info to help diagnose.

      If you dont think you have the time or inclination to find and fix the problem, you might want to contact some local inboard dealers and see if they have any time to take a look. Any Mailbu/Tige/Moomba/SAN dealers in your area? Maybe some of them can help sooner than the MC dealer (or recommend an independent mechanic).

      Just a thougt and good luck!

        Def should hear the pump kick on and as Thrall said see the gauges cycle immediately after turning key. If not, there's an electrical issue. Does the starter engage, click, anything when you try to start it? Is the kill switch bad? IIRC it cuts power to the fuel pump. (Just because lanyard is attached, doesn't mean its working) A simple test light should help isolate the problem.

          There is a circuit breaker on the port side of the engine. A red button. Reset it.

                I had this issue with my '03 x-30. It was the safety lanyard kill switch. I pulled the wires and jumped them together...everything worked. Hopefully it is that simple for you

                  I had the lanyard kill switch problem last week.
                  I was on the water wakeboarding and when i finished my set, my girlfriend stopped the engine. when i got back in the boat, it would not start. it was cranking but not starting. After 5 minutes of checking things, i removed the lanyard and re-installed it again. then it started as normal. 10 minutes later, same problem. i had to shim the lanyard kill switch with this :

                      That was my second choice. My first was having my girlfriend holding the switch while i do another set

                          Thanks for all the replies so far everyone...appreciate it. Since I'm being passed on this info from my Dad (who's talking to our mechanic), I may not have all the answers as or now. But here is an update from our mechanic:

                          - narrowed down to an Electrical issue. The boat engine cranks, but it won't fire up obviously.
                          - there is no fuel getting to the pump, even when the new one was installed.
                          - he tried the port reset button (kill switch) in the engine to no avail.
                          - he's wondering if there is a wiring diagram available for 2003 MC boats. It would help him with a diagnosis.

                          My Dad has contacted independent boat mechanics as well, since any nearby MC dealerships are booked solid for the next 2 weeks. They all seem to think that a specific MC software is needed to diagnose any electrical issues, etc. So we're kinda stuck in the current situation for 2 weeks unless our boat mechanic can get to the bottom of this.

                          Hope this info helps...any new suggestions?

                            I assume you mean no power to the pump? The kill switch and reset button are 2 different things. By kill switch we are talking about the button by the throttle that the lanyard attaches to. Sometimes the switch goes bad and even if the button is depressed, the connection will not be made, thus resulting in no power to the fuel pump. Its easily checked with a test light by checking the wires on both sides of the switch for power with the key on.
