Re: [Amel Yacht Owners] Masse Light and March Pump



I am almost 100% sure you used the wrong pump and I am 100% sure the UP-3 is not magnetic, unless this is something that Marco made in the last 60 days.

I recommend to Amel School Clients, either of the following MARCO pumps for freshwater:
BEST:UP14/E Electronic water pressure pump 12.2 gpm Part N 16469015
GOOD: UP12/A Water pressure system PTFE gears 9.5 gpm. Plus ATX2 Stainless steel accumulator. Part N 16468013 & 16508110
OK: UP6/A Water pressure system 6.9 gpm. Part N 16462013 & 16508110

BTW, Amel School Clients get a 20% discount when ordering in the EU from MARCO, or in the US from MARCO's partner MATE-USA. If you are interested in becoming a client and owned your Amel at least 1 year CLICK HERE for information.

I hope that this helps you.

I replaced the freshwater pump with a Marco UP3 electronic gear pump.  It has a magnetic drive.  The old pump had a bonding wire, so I attached it to the base of the new pump.  I did not hook up the "active" red light on the 24V power panel however, since we can hear this pump operate.

Now I'm getting a warning light on the "leak detector" for the bonding system for the "Ground +".  When I shut off power to the water pump, the warning light no longer illuminates.    

Since this unit uses a magnetic drive, is that causing some voltage in the bonding wire?  Should I simply disconnect the bonding wire from the pump?
