You wiring for the boat has 3 wires to the pump. Switch, auto (hot all the time), and ground(common). The auto wire connects to the battery via a fuse near the battery. Check the fuse. The prior owner of my 200 had a non-automatic pump installed with just two wires to the pump. I replaced with a three wire automatic pump. Best to be safe with a working pump.If you store your boat on the trailer, you can always use a garden hose to fill your engine compartment to test your bilge pump. It should kick on automatically once the water is about half way up the pump. If it doesn't kick on, the float is either stuck or broken. Then try the manual switch to confirm the pump is actually working. If it's not you'll need to check electrical connections. If they're all good, then you may need a new pump.
