Went to change the oil on my Panda 10000i genset today (160 hours) and discovered dried salt all over the front of the unit. I think the likely culprit is the sea water pump seal, based on the rust by the weep hole where it mounts to the block. Iíve ordered a new pump and will rebuild the old one as a spare.
Otherwise this genset works as it should.
Anyone ever remove and replace the sea water pump on one of these Kubota engines? Canít find documentation of how to do this.
Note, Fischer Panda advised replacing this pump as soon as possible. A catastrophic sea water leak from the sea water pump quickly fries the electronics on these gensets, apparently. This is a known fault with these Johnson F4B-9 pumps, according to the US distributor in FL. 160 hours/2 years is a pretty short life span. Sheesh.

Kipwrite,

We have a FP 10Kva unit onboard and have had the same problem. The pump is crap. We now have 930 hrs after our 4 year of liveaboard and purchased a a new pump, rebuilt the original pump and then both had the same issue again. I have just had both pumps rebuilt over winter.

To remove the pump -Remove the water hoses after turning the water vales off, then there is a bolt (about 7mm - 1/4in head size and about 50mm - 2 inches long) which goes through the clamping arrangement which holds the pump on the motor. Once you remove this bolt you will be able to pull the pump out of the motor housing. You don't need to remove any other bolts, just this one.You may need to use a flat screw driver to pry the pump out and maybe a back and forth twisting action will help. But it will come out.
