A picture would help. Not sure why a bilge pump would in the forword cabin area since it's the highest point of the floor. My c22's bilge pump is under the cabin step. Are you sure this isn't an old paddle type knot gauge transducer and a depth finder transducer? That's where mine are.
Also...bilge pumps have hoses connected to them, do these have hoses?. If the boats on a trailer look under the hull in that area. You may see a little paddle wheel on one and maybe a mushroom shaped plate on the other. If so, they are transducers. Maybe your displays are gone but the tranducers still remain.
