I have just installed AC on my 2002 Beneteau 331 and I am looking for a condensation pump. I saw a pump on a Beneteau 37 but was unable to find the manufacture. Also looking as to where to drain, sink or drill another hole in the hull to drain the water.
Condensation pump for AC

Do a search for a venturi tube. Install it on a "T" in the discharge line from the A/C pump. No need for a separate thruhull as the condensate will be drawn into the discharge water flow.
That would be the Mermaid Condensator. It works on the venturi principle and uses the AC water coolant discharge hose to extract/discharge the condensate. It is vital that you check and clean the condensator filter.
Actually, any venturi tube will work and cost substantially less than the one marketed as Mermaid. All you need is some tygon tubing or anything similar and a venturi from any water bed store or hardware store. No filter should be necessary
Its a Beneteau thing - draining to the bilge is a poor option. We have this grid system, and while it makes the boat super rigid, it doesn't facilitate good drainage to the bilge sump pump. Water pools and mildew ensues.
Your other option Richard is a reworked shower sump kit with float switched pump. This requires power, and a discharge point (thru hull). You may be able to tie it into another thru-hull, include an anti-siphon loop. Didn't work for me, so it was the Mermaid.

The shallow bilge also creates another issue and that is normal float switches wont actuate the bilge pump until the water is well over the sump. I just purchased a Water Witch Mini 101 electronic bilge switch and plan on installing it as deep in the sump as possible. I already have the condensation tube draining into the sump.The new switch will activate the pump sooner and prevent water migrating between the bilge compartments. It worked on our B361 and expect it will handle our 43 as well.
Gunni, the AC pan has two condensation drains, one to the condensate pump and a second one for overflow. It's the second one that was routed to a compartment just in front of the bilge allowing water to migrate everywhere. I bought a double ended fitting and length of hose and ran it through the limber hole and back to the bilge sump. That's when I realized the float switch internal to the Rule 1100 bilge pump's actuation point is 2 3/4". Unfortunately that's just above the point water begins to spill out of the sump. I hope to install the new switch this week while on vacation. I expect it will help keep the sump much dryer. I'll also clean the condensate pump filter which should minimize any condensation flowing from the second drain and into the bilge.
This is our second season with a B331. The A/C drain has been problematic from the beginning. It was supposed to drain into the bilge, but found its way to the engine compartment... stopped there. Beneteau's fix is a small pump and separate through-hull. I opted for the Mermaid Condensator. Works well, except the installer kinked the drain hose. I installed a plastic ell fitting. Should be fine now.
Richard, I installed a shower sump pump the first season that we had our 331. The tank for this is approx. 6" x 10" x maybe 5" high. It has a small bilge pump inside. I put a thru hull near the thru hull outlet for the AC discharge. I placed it on the port side under the aft bed, close to where the AC pump is. I did that in 2004, so far so good.
