Deckwash install question
Submitted by beeroclock on Thu, 2025-01-23 16:53
Hi guys im planning on installing a seaflow deck wash its specs say its max amp draw is 12A and its fuse is 18A. Should i still run an inline 18A fuse between the positive battery terminal and the pump? there is no inline fuse on the positive wire of the pump (i presume the 18A fuse it has is internal). Im planning on running it to its own basic toggle on/off switch installed near the pump (not through the main boat dash switch panel) cheers for any advice

fuse?
if you cannot see a fuse on the pump already, install an in-line one as you described

20 amp
yes you still should have a fuse between the pump and the +ve batt terminal, and a 15-20 amp fuse is what you should use.
most switching panels these days are fused, so if you havent bought it already, buy a fused switch, or switch panel.
For the record, I run thick gauge (6mm) dual core wire from the battery/battery switch, to a 6 or 8 gang fused switching panel, then reticulate most of my hardware from there - freshwater pump, saltwater pump, trim tabs, lights, etc. I do another run of 6mm dual core to a fuse block ,and all other hardware (plotter, VHF, stereo, basically anything that already has an on/off switch inbuilt) runs off that.
any appliance that has a big power draw, like anchor winch, pot winch, etc, I use individual 10-12mm cable direct to the battery, and marine grade circuit breakers and solenoids instead of fuses. anchor winch breaker is rated to 120amps.
