Would replacing aerator pump with simer require relays?

[wakejunky]

I'm going to replace my aerator fill pumps on my 03' rear tanks with simer pumps, does anybody know if the power to the existing aerator pumps are relayed or would I have to interface a relay in line with the power? I'm tired of the helm valves getting stuck closed and/or open and I figure, I'd rather wait to fill than continually have check the tanks when I don't want them to fill.

I'm not sure, but I think that you are either going to have to re-wire with heavier gauge wire or use relays. Impeller pumps can have a 20 amp draw, which is much more current that aerator pumps. I think I used 10 gauge wire on my Johnsons. Whatever I used, it was the biggest wire that I could find quick connects for (which I needed for my switches). I also added in 25 amp blade fuses and a fuse block for my 3 pumps.

I did the same as chexi. I added a separate fuse block with 20 amp blade fuses and ran 12 gauge (or 14) to the switches. They work great, although I wish I could figure out how to determine if the bags are empty other than trying to hear a difference in the sound of the pump, or actually looking. tough to hear over the music, engine and people, as wel as tough to rearrange the boat to look
