In that case, I'd sleep better with an automatic bilge pump. I like Jimmy's setup. Out the back where healing can't submerge the outlet.

I also considered hard wiring a bilge pump with an auto feature and a proper bilge pump switch with Man/Auto function.
After some thought I figured a portable pump would do just fine as a couple members here have already mentioned. A big sponge and a
bucket for the rain water that comes in top side also works well. I'm hoping to rectify some of these top side leaks this summer.

I wired the pump with battery alligator clips but also kept the automatic mode using another battery clip so I have manual or auto option. Not sure yet where I would discharge
the water if I was to leave the boat for an extended period if in auto mode. Option is nice. See pic.

I have a large bilge pump mounted under the ladder in front of my batts with a band clamp that,s the lowest part of the bilge in that area the Hull runs up from there to the transom about 1 1/2" mine also runs aft and my through hull runs out of the transom also high above the water line , I used heavy wall clear vinyl marine tubing designed for bilge pump use it lets u see if anything is growing inside it or if there is a blockage plus less restriction to flow , also make sure ur bilge pump is rated to pump as high as ur installed through hull fitting
I,m not a fan of those white plastic core-gated bilge hoses they reduce the flow rate of ur pump quite considerably, they trap water which also allows unseen mold to grow & they r prone to splitting with age :o

I don't think I would have enough room to mount it there. I will definitely change out the corrugated hosing to something smoother.

I just installed a rule 500 gph pump and a float switch under my batteries on my '02 26x.

I wired one switch for auto using the float switch, and another switch if I just want to turn the pump on. I live in AK where it rains a lot and last summer I got by using a portable pump with a bucket, but this year I want piece of mind when it's raining and my boat is 2 hours away in a slip. I can't confirm that this one pump is enough or how well it is going to work yet, but it seems like thats the low point on the port side.

If I install another one, I think it will be under the bathroom sink on the starboard side. I feel like those two spots are the lowest and are a pain to get to with the portable pump. A third pump back and center under the beds would be cool too, because there is another low point back there, but I think thats the easiest for me to get to with the portable pump if necessary.

We'll see how the first pump works and go from there. Hopefully it's enough.

I installed the pump because my chain plates are leaking bad when it rains. Just posted a new thread if anyone has advice on sealing them.
