On my boat I have 2 bilge pump switches. The switches are labeled port and stbd. Obviously I have 2 bilge pumps. The switches only have 2 positions...either on or off. No way to switch the pumps to auto so that they come on as needed..? seems odd seeing as though the bilge pumps appear to have built in float switches. need some info as to why the pumps are wired with 3 wires but no provisions for a auto feature

The auto is hard wired in so you can't shut it off.

^^what he said. Hard wired. Out of your control.

ohhh so my floats that are built in the bilge pumps must not be working..?

Odd for both to go out at once. Check wiring. Bilge pumps usually have 3. Ground. Switch. Float/all time hot. It's possible someone replaced and wired backwards or something. Also the pumps are old. Likely the lovetts. I just yanked those. Not made anymore I'm switching to rule. Motors are out so I'm replacing all the hidden bs. Lol

yes my pumps appear to be original. and they do have 3 wires going to them. They do not automatically start up if I fill the bilge with water though. If I flip the switch they both work great. just hate having to flip the switch

Check your breaker under the seat

Also my old ones the float went bad or stuck. Went with rule for the new ones.

I'd consider new pumps. 20 years is a good run. Lol. Also what power/speeds?

Mine are just like this and they automatically come on when needed.
