Shouldn't be a bilge pump under the engine
Sounds like you have some kind of leak. Soak up the oil with something absorbent. Just about anything will do - you do not have to buy the little oil pads. Rags, paper towels, toilet paper, newspaper, sawdust all will absorb the oil. Discard of them appropriately. It is a messy job so be prepared. If you are a brave soul, you can try just a tiny taste of the water. Sweet is coolant, salty is salt water, etc. Add some dish detergent - a small amount will do - think drops per gallon. Pump it out or sponge it out and clean and dry the area.To determine where the water is coming from, first check the coolant level to see if it is down. If the coolant level is ok, you can try running the engine with a clean dry newspaper spread underneath it to see where it is coming from.Caution, keep your hands out of the engine compartment when it is running. If you have a pinhole fuel leak, you may not see it and it can spray out under such pressure that it will penetrate your skin. If you have to trace such a leak, use paper on a stick or similar to locate it.
