If the mfg put one in the bilge pump switches should be next to each other. If they did not and the PO put one in there still should be a switch in the dashboard area. The next thing to do would be to verify where all your thru hull fitings originate from.Generally if you had a forward bilge the thru hull would be in front of the helm area. If you have lifted the floor access hatches and don't see anything the odds are there isn't one. If you have a shower ,that usually drains into the bilge where the forward pump would then operate and dump it out.
