Should I run an un-switched line from the battery switch (that is, from the Bat 1 post) to my bilge pump switch (through a breaker, of course) so I could leave the bilge pump on ¥¥¥auto¥¥¥ while the battery switch is off? Or is that a bad idea? I don¥¥¥t like leaving a boat with the battery switch on, but there may be times when I want the bilge pump to run automatically.

Loafer - simply remove your plugs when you leave the boat and leave the bilge pump off - automatic draining. This has been "kicked around" a few times before, so using the search function will show you the other comments. --- Jerry/Idaho

Wiring an automatic pump to the battery via its own over-current protection is often done. The only drawback to this type of installation is the potential to drain the battery if something causes the pump to become stuck ON, for example, some debris under a float switch, or if the automatic feature of the pump malfunctions.

If your boat has self draining, like most Boston Whaler hulls, and you have to leave it unattended in the water, many opt to permit some water to accumulate in the bilge sump in preference to having the automatic pumps left in operation.

That is how I ran my two bilge pumps. I actually put mine on a 3 position switch, with the first position being the main bilge and the second also including the pump in the splashwell. If you plan to leave it on, I would suggest a solar trickler charger.

Thanks for the responses¥¥¥ since this hull (¥¥¥74 Revenge 21) is new to me, and I haven¥¥¥t even hung the engine yet (I know, I know¥¥¥ wasting time on cosmetics and trivia such as wiring), I¥¥¥m not sure how high the water will come with the plug out. And as much as I don¥¥¥t like leaving power on while I¥¥¥m away, I like the idea of saltwater in the cockpit, above the fuel tank cover even less.

However, I plan to keep her on a trailer most of the time I¥¥¥m not Whalering, so I think the unswitched power and three position (off/auto/on) bilge pump switch will be the best combination when I do have to leave her in the water.
