    2452 Ciera Express - bogging down and stalling

    1995 Bayljner Ciera Express 2452 with 5.0 Merc

    Problem 1: after coming out of the hole and being on plane 4 a couple of minutes the engine bogs down. If I continue at idle speed within 10-15 minutes the engine bogs down again and will not start. If I wait long enough it will restart and the issue will repeat. I am thinking some kind of gas venting issue perhaps? The engine does not overheat. Any ideas from the local gurus?

    Problem 2: easier, neither of the trim tabs are working. I checked all the fuses and they are fine. Any suggestions?

    thanks a million in advance for any suggestions you might have!

    Sounds like a classic plugged fuel tank vent line, you can test this by running her with the fill cap removed. If the problem goes away then your vent fitting is likely plugged up.
    Bennett tabs? Test for voltage at the switch and then the pump.there are several good you tube videos from Bennett on trouble shooting tab issues.
    here's a start.

      Thanks a million!! . . . . Hmmm, sounds like that could very well be the issue. Is it difficult to access and clean the vent line? Any hints? I have not had the boat long so I don't know it well.

      Thanks also for the tabs links I will start digging in and trouble shoot.

        Should be a vent fitting for the fuel tank somewhere on the exterior of the boat, mine is located high on port side transom. Original vent fitting probably looks like this. They can become corroded and closed up or bugs make nests inside etc.

          If in fact it turns out the vent fitting is corroded up I'd just replace it with a quality stainless type fitting. I've used this type on mine.

            Thank you so much!! I might just replace it anyway just to make sure and eliminate one possibility.

            Cheers

              Are you reading the temp gauge or using a infrared thermometer gun? I was having a similar issue, boat would run great then lose power and die. I thought possibly a collapsed fuel line , plugged vent or ignition issue. my temp gauge was showing 175 but my temp gun showed almost 220 at the thermostat housing!

                I will look into a clog fuel tank vent line and then go from there.
                I sounded confirmef one vent line to the gas tank. it is aft of the boat. there are two others on the port and starboard side That are identical. does anyone know if they gas tank is vented through one vent line or does it have one in the front and 2 on the sides?

                  One vent for the gas tank, one for the fresh water tank and one for the waste tank.

                    I would first run the boat with the fuel fill cap loose to see if the problem goes away, this is the same as adding a vent.

                      Agree this should be tried first.

                          Sorry guys, I was out of pocket for a while but I am back.

                          the issue was easier than we would have suspected. It was the gas. It was old and not firing properly in the cylinder. Dained it, put high octane gas and ran like a champ.

                          it was too big for me to tow so I sold it and bought a 2002 Ciera 2252, which i am now trying to get seaworthy.

                          thanks a million for all your help.
