Amel Super Maramu 2000
Automatic Bilge Pump and High Water Alarm
Following the recent alarming leak from the bow thruster (1 year after being services by Amel Martinique at a cost of $2000 / 2700 Euro in Nov 2012) and after hearing several similar stories from Super Maramu owners, I decided to add an automatic bilge pump and high water alarm.
I looked at battery operated high water alarm, but many reviews were negative, so decided to go with a wired one (24 Volt).
I chose the:
The Rule Fully Automatic Bilge Pump Model 25S-24 will start every 2.5 minute for half second. If there is water it will pump it out, until empty. If there is no water will stop (after half second).
I did some test, putting several gallon of (fresh) water into the bilge, it works well.
I put the high water alarm in case the bilge pump fails.
Richard mentioned I could get 24 Volt from the power panel above the door to the forward cabin and then run the wire through the drain hole in the forward hanging closet which I did.
For now, I connected the water hose into the shower with a hose going through the wood cover as a temporary installation. An option is to connect it into the T on the hose going to the Bilge, but the Rule Automatic Bilge Pump instruction manual mentioned to NOT USE A CHECK VALVE.
For the on/off switches for the bilge pump and high water alarm, I put them on the cover (see pictures). I made sure to use long enough wire so that I could have the panel resting on the floor.
I work slowly, so it took 2 days to complete the whole work.
Mistakes I made:
For the bilge pump wiring, I used 14 gage wires I had; I believe they are automobile and not marine grade.
What I could have done better:
I used heat shrink connectors everywhere, except for the switches (On/Off and Auto/Off/Manual) as I run out
Below you can see I unscreew the connector
Cover panel with 1 switch already installed by previous owner (for Furuno PG=1000)
Wiring in the hanging closet
bilge pump high water alarm
Switches and siren before labels
Hose to evacuate water from bilge pump
To the shower (this is a temporary set-up)
Or going through the wood cover so no one will fall in
Can still open for inspection
Very long wiring to allow the panel to stand on the floor
The wire are going to the left of the picture (starboard side) down to an existing hole, down to hanging closet compartment
Close up with the 4 new wires connected
I kept the same concept as Amel dud, if water comes from the mast, the curve wire will let it flow down
Most the wire folded in
Added the labels (using clear "Avery" labels)
