Gidday from OZ.
Was replacing the impellers in our x3 ballast pumps yesterday in our 14 Mondo and was a bit shocked to see that the board that the pumps and control gear mounts to was not secured in any way to the boat. The board had brackets at the bottom and one to the engine side (pumps etc on the port side rear) but no screws or mounting hole noted anywhere. The wakeplate wiring kinda stopped the board falling towards the bow when the carpeted trim panel was removed and that was it!
It's been 6 years since we bought our boat and figured about time to replace the impellers, none had the blades broken off but a couple were deformed.
We do listen to the pumps and switch off when they make a dry pump sound.

Thinking of positioning the board and drilling holes to secure but wanted folks input, I'm not too excited about drilling holes into the fiberglass floor but not enthused by letting things rock around as before either. The wakeplate wire insulation on one of the wires had rubbed thru and the wiring exposed, wrapped in amalgam tape and sleeved with corrugated conduit sleeving.
