    Water leak at transom-gctid556617

    What are the possible areas that water can come through the transom/gimbal? So far I have u-joint bellows, shift cable bellows, trim sender wire access, hydraulic/mercathode access, steering shaft seal, raw water intake, and speedometer tube. Am I missing any? I replaced the two bellows, trim senders, and water intake hose. Its possible, although unlikely they would be leaking. However, It looks like I have more than one leak at this point. There is a tiny amount of water building around the steering lever area, and there is a steady drip, drip, drip coming off the y pipe. I haven't been able to chase it down any more than that. Sad that it has to come back out of the water...

    Can you tighten down the bolts that hold the actual gimbal to the transom ?

    If you can turn those bolts more then one full turn, there can be a problem "s".

        A very common issue is the steering shaft corrodes and then wears the seal down. Your description of where the water is building is dead on for this. Pita of a job to fix. They sell aftermarket Stainless steel shafts on eBay cheaper than the regular steel mercruiser stuff. http://www.ebay.com/itm/Mercruiser-U...6ec279&vxp=mtr

            I'll go with the steering shaft and seal. If the OP replaced the seal but the shaft is warn then it will still leak.

              Agreed. I assumed the op would not put a new seal on a worn or rusty shaft. My bad

                Let's see first if he can turn down the bolts.

                Seems he did everything else.

                  Yeah, in addition I would get the top end steering shaft sealed up and see if the Y-pipe leak goes away. I'm assuming when you say Y-pipe you mean at the bottom where it's held in by the 4 bolts? It could be overflow from the steering shaft leak.

                  Also; how much water is accumulating during the course of the trip/day? Don't want to be a shade tree type of guy, but if it's not too bad and you were diligent about checking and making sure your bilge pump was operating correctly you could possibly live with this for a while.

                    The only thing I did not do was the steering pin. I will check the transom bolts tomorrow. I am in salt so any outside water sloshing in the bilge is rust city! Gotta get her tight...

                      Transom bolts are tight. Taking on about a gallon a day. Definitely see water at the steering arm. It looks like a bit of water is pooling up in the grease around the drive shaft as well, so I guess it could be rolling down. I've been waiting to pull her hoping I could get that A-HA moment. It's so difficult fixing a problem you can't pin point.

                        Ok. I've found the drip coming off the top of the y pipe. It slowly pools up along the two dents/channels at the top and then drips down off the exhaust pipe bolt. Ideas?

                          Steering shaft is leaking. Shaft and seal need to be replaced.
