Earlier in the Summer, we sold our pontoon boat and bought a 2000 Monterey 220 deckboat with a 5.0L Volvo Penta Motor and SX outdrive; changing from an outboard to an inboard - with no inboard experience, but I've learned a lot from reading on this forum. The boat has one bilge pump - that I can see - right in front of the engine. But I have yet to see more than a 1/4" or so of water around the pump. If I turn the console switch on, the pump runs whether there's any water around it or not, so I'm assume that it doesn't have a float switch. That said, after spending a few hours on the lake, when I pull the drain plug, I always get a fair amount of water (estimate maybe 2-3 gallons?). Is there another bilge pump down in the drain plug area? Should there be? Since there's never much water around the pump, I almost never turn it on. Should I just leave it on anyway, or will it hurt it to run without water? I bought the boat used and without manuals. I've downloaded manuals from the net, but they're pretty generic and mostly safety related.
