On the 2018 33 Express the shower pump is located in a box below the cabin floor. The pump burned out and the water was overflowing out of the clear plastic box. Next to the shower pump box is a hole, which the water spilled into. Does that opening lead to the aft bilge pump?

It's called a 'limber hole'. And yes, if not plugged from the other end of that hole.
IMHO, it should never be plugged!

Some seen in the past that some limber holes are plugged, dont know why? Suggest OP should look at a Johnson 1000 GPH Sump pump with electronic water level switch ($98 when we purchased it from Amazon).The 1000 GPH do the job when taking long high water flow showers so they can keep up with waste water! No problems since installing this electronic switch controlled sump pump version (both sump pumps are now this version) , just dont wash anything with grease on it (dishes, etc.), wipe off heavy grease with a paper towel then wash dishes in the sinks..We pour about a pint of H2O2 (Hydrogen Peroxide) down all sink/shower drains about 3 times per year (also, about 1/2 pint in both HVAC drip pans, keeps the pans from getting mold/scummy etc.) , pumps still working great. Our older float level switch pumps were a PITA as the grease etc. just caused the float to stick down and not actuate the pump motor. Last bit of advice, never pour bleach down anything in the boat, even toilets!

I had the Johnson 1000 GPH pumps for both sumps Forward and Aft on my 4460. The pumps worked great, but I normally had one of the two electronic float switches go bad on me at least once a season. After the first two years, I ended up always keeping one of the electronic float switches on hand when one of them would end up going bad. When I swapped the spare for a broken one, I simply ordered another one. I would recommend that you keep at least one electronic float switch on hand. I never researched what could be done to clean them or why they go bad though. Perhaps the peroxide flush on some regular interval would have helped.

That being said, I'm on my 3rd boat and also have an unground pool with auto cover. Point is, all of them, from time to time had pumps with electronic switches (Not to be confused with electronic FLOAT switches). Every one of these failed, in my opinion, prematurely! The installation of separate mechanical float switches and a quality pump have solved all problems.! |

The electronic switches will work for a long time. Since installing the 1000 GPH Johnson's and complying with my previous post, no problems in 4 years. Do the H2O2 treatment and once/twice a year remove cover and look into sump, if a little cruddy flush it out and should be back in service? Also, if sump overflows effluent should end up in one or two of the bilge pumps if limber holes aren't plugged.Not sure why these holes would be plugged in the first place?
