Default Backup Bilge Pump anyone??

I have a Cobia 240 and was wondering if I should install a second bilge pump. It was an option when I bought the boat that I passed on, and the boat is pre-wired for it. My installer want's $600 to install. Any thoughts or recommendations? How many of you have a backup or second pump.

thanks

Yes, properly install a backup pump system per ABYC specifications.

My engine room has three, one is an emergency high-level pump.

Yes. But just as important is to check/verify the operation of the pumps AND the float switch regularly.

Easy to install especially if already wired. But you need to install a thru hull too.
But again, easy so long as you can get to it

I can't imagine running a 24' boat without two bilge pumps. $600 estimate probably based on difficulty of connecting pump to thru-hull fitting.

You need two especially if you go offshore

i would probably have two fixed mount on that boat and one portable that can be dropped in

redundancies include wired to different battery, separate overboard hose, etc

Yes you need one, make it totally separate from the other one.
I can't imagine owning a boat that size and not being able to install a bilge pump.

I installed one of these on my last boat as a backup. Auto sensing bilge pump. I put alligator clips on the wires and just hooked them up directly to the battery when I put the boat in the water.

Still have to run the plumbing line and drill a hole in the side of the boat, but parts total around $100. No way I’d pay $600 for this job.

Had two bilge pumps on last few boats. They should be wired separately and one should be wired so will pump regardless of battery switch on/off. I replaced one on last boat when one took a crap (important to test them, better to find out at the dock), not difficult to do, just PIA working in bilge area.

People say $600 is too much but if the access if not so good $600 might be a good deal.

I think it is important to have two bilge pumps and to test them regularly.

I have had a bilge pump die on me offshore before. For that reason I keep a rule evacuator on my boat at all times now in addition to the two bilge pumps.

1 1500gph on a float switch and a backup 1500gph rigged as a crash pump.

Add another fixed and then carry a spare 1500gph with alligator clips and the appropriate length of wire. Can drop it into forward compartments if you had to.

$600 seems high to me. I had a 2nd pump put into my 214 2002 Cobia for less than that. It's a bitch getting access into the bilge on these boats, and the hatch is located on the swim platform, so you really couldn't open it to put a portable in if you are taking on water (opening the hatch at that time would likely let water into the bilge). I also installed a bilge alarm.

My boat came standard with two bilge pumps . One is forward and one is aft and I have a high water alarm as well, standard. I would suggest you install it forward and perhaps the price is worth every penny depending on your skills and ease of access.

I got 2 on my 23ft, one sits higher that the other, both have auto switch plus a wired switch to the console, each feeds from a different battery bank. I like Johnson, have used rule in the past as well, not sure if one is better than the other but prefer Johnson cartridge type.
