I am experiencing fuel system problems with my new NC 895. Its hull no 33. Its one of the first if not the first 2019 model from Cadillac. We took delivery this summer. Jeanneau America has made changes to the fuel system on this boat. These changes are not yet indicated in the manual as it shows the previous system. This is the boat with a single F300 Yamaha that was so late for delivery as chatted about in some of the forum threads.
Here is the first problem. The fuel fillers have been relocated on the port and starboard side walkway surfaces with the vents directly above. They were previously on the stern above the swim steps. I presume this change is to have the locations better protected from sea water entering the system, but I don't know for sure if this is the reason. Cap'n Ron reported on the problem of water entering the Attwood fuel system on his 795. See the recent thread titled "You more than likely have water in your fuel system" for more info. Anyway, the relocation of the fillers and vents would appear to be a good idea if executed properly. But it appears there may be an issue with the design. The dealer initially had problems getting a full tank of fuel into the tanks. When filling, the fuel would at some times back up in the filler with fuel and air bubbles as if it was full when the tank was not full. In fact the dealer (Sundance) attempted to fill both tanks for delivery but upon delivery I determined that the one tank was approximately 40 gallons from being full. I filled that one tank by slowly adding more fuel even though the fuel nozzle kept shutting off due to the backup of fuel. I've had this problem to some degree every time I put fuel in the tanks regardless of the amount of fuel in the tanks. At the 2nd time I added fuel (since new) I managed to get a significant amount of fuel in before I started experiencing the backing up of fuel and the nozzle shutting off. The last time I added fuel (after the tanks were empty - more on that below) it was very difficult and took a long time to get 40 gallons in. And the entire time fuel with air was bubbling near the filler and backing up to the top of the filler. This was so extreme that no matter how cautious and slow I went I still spilled some fuel. Today Sundance sent Seahawk Yacht Services to look into this problem and also some other warranty items. Alex from Seahawk opened things up and immediately had concerns on the placement of the charcoal fuel canisters. The suspicion is that the fuel canisters due to their location are getting fuel trapped in them and thereby not allowing the air to pass through and vent properly. Alex is contacting Sundance to determine how to proceed.
Now the 2nd problem. I ran out of fuel. I was very lucky in that we were in a small protected marina and folks immediately came to our rescue. Prior to this we had just crossed the Straight Of Juan De Fuca. Lucky we didn't run dry there! Both fuel tank indicators indicated 3 bars of fuel, which should have been approximately 1/3 full in each tank. Alex also looked at this today. I informed him that the Sundance folks told me they didn't calibrate the gages as it appeared they were working correctly. And he is pretty sure that is the problem. But before calibrating he wants to check into the fuel sensors as the sensor part numbers (in the left and right tank) do not match each other, and also make whatever changes are necessary due to the venting problem. Once this is all sorted out then we will need to empty the fuel from the tanks and perform the calibration. Bottom line here for you new 895 owners is make sure your fuel system gages are properly calibrated.
