Bilge Pump Systems for Powerboats

A bilge pump is typically located at the lowest point of your boat in a standard powerboat bilge system (below the floorboards). That should suffice for most powerboats, but today’s faster, higher-priced boats and yachts may need more. When you’re flying, the majority of the bilge water moves to the aft area, where it can dig your stern deeper into the water, extending your draught and robbing you of your fuel economy! Let’s see what you can do to improve your fuel economy and safety.I strongly suggest you to visit https://medium.com/@merritt_supply/if-you-do-not-know-what-a-bilge-pump-is-read-on-854a5e17b630 to learn more about this.

Check to see if your current bilge pump system is properly installed, including the pump, auto switch, and wiring. For most midsize powerboats, a primary pump with a capacity of 1500 to 2000 gallons per hour would suffice. I like to connect a “Buzz” alarm to the bilge pump system (like your low oil pressure alarm) so I can keep track of how often it goes off. You can also instal a light on your steering console that turns on when the bilge pump is enabled. When you see the bilge pump running often, you know something is wrong. It’s possible that a prop shaft packing failed, or that a through-hull hose or hose clamp came loose, allowing water to reach the bilge. You’re inspired to get into the bilge to figure out why the alarm is going off so often before it gets out of control. I also installed a backup bilge pump (3000 to 3500 GPH) with a float switch higher up in case the primary fails or, even worse, the primary can’t keep up with the water entering the bilge! With this type of setup, you get a sense of security.
Now, when you’re flying along, it’s a smart idea to have a small bilge pump mounted in the stern region to remove any water that accumulates. You can have it on an automatic or manual switch…the choice is yours. If you’re powering inshore to those beautiful harbours for the weekend with friends and family, or powering offshore for big game fishing, getting this type of bilge pump system keeps you in control. And when you’re not on board, a persistent warning from your powerboat attracts attention… Have fun cruising!
