Have a new 410 (everything working very nicely so far, thank you), and noticed recently when inspecting the engine compartment that there is about 3 or 4" of water in the molded in pan under the engine. Surprisingly, this pan does not seem to drain into the bilge. I am tempted to poke a hole in it and let it drain. Anyone know if this pan should drain? If not, where does the water go? Should I expect this pan to be dry? I've been too lazy thus far to pump the water out and see if it reaccumulates. Any comments appreciated. S/V Breathless

Engine Oil
On our 380 we have the same type situation. I think it was designed to contain any engine oil that may leak or spiil. But where the water comes from is a differant question. I can't tell if it comes from the shaft seal when heeled over or from the anti siphen valve above the engine Andy Hansom 380 Vanishing Point

No Holes There
The pan is designed to hold any oil that is lost from the engine. If it were to drain to the bilge it would be pumped overboard and brake about a zillon laws. Our 430 is always dry there. Probably ota dry it out and see if it reappears...could be the sign of a problem..Congrats on you new Hunter Dick McKee s/v Constellation

by design
Steve: Several of the models are designed this way. Our 1985 H'31 has a limber hole between the engine bilge and the secondary bilge, but other do not! I am not sure why the boats were delivered this way. We always keep an oil absorb cloth in our engine bilge so we can contain the oil and any water from the pack gland can seep through the cloth. I would drill the hole and leave an absorb cloth in both bilges. This will keep the water off your floor and oil out of the bilge too.

From cooling system?
The water is probably from the cooling system. See if it's salty or fresh (by taste, or look for color if you have coolant in the fresh water system. There is probably a leak somewhere. Are you finding your coolant level going down?

Water
This may be a worthless post, but ............... We recently took delivery of a new 450. The other post are correct that the engine pan is isolated for possible oil spills. The water when it reaches a certian height will spill over into the bildge for the bildge pump to remove. But back to your condition. On the 450 the water cooled Fer/Freezer unit is located in a cabnet above the engine compartment. Whent the boat is delivered by Hunter, the condansate line emptys into the engine pan. Therefore if you have a water cooled Ref/Freezer, were is the unit and condansate line located. I re-plumbed all my lines including the Ref/Freezer, Air Conditioners, Dry Sink, ect. to shower sumps. Hope this helps.

probable culprit
That water shouldn't be there, and probably indicates a leak. It may be that the water hose coming off your dripless packing gland is the culprit. (This was the case on my 410 originally.) Try this test: watch the end of that hose while someone puts the transmission in reverse and revs the engine. If water spurts out the tube, you have a problem. The quick fix is to install a stopper at the end of the hose, which is what my dealer did, but a better idea is to splice the hose into the raw water channel on your cooling system. I had my mechanic do this, but am told that someone with minimal mechanical skills could do it himself. Whatever you do, do it quick, because if it's salt water getting on your engine you're going to have rust problems. Within the first month that I owned my 410 I already had rust on the aft starboard engine-mount bolt as a result of this problem. By the way, if you poke a hole in that pan you will potentially allow oil to flow to the bilge. Not only will this screw up your bilge, making it almost impossible to clean, but it will buy you a load of legal trouble as well as the distain of fellow boaters who will have to put up with your oil in their marinas and waterways.

Another possibility
I would look closely at the dripless seal also (assuming it is dripless and not packing). John mentioned the water hose feeding the seal as a possible culprit. That is certainly a possibility, but not all seals have this water hose (maybe all 410's do, I don't know). In any case water hose or not, when the boat was first launched, perhaps a diligent yard worker burped the seal (necessary if there isn't a water hose) to allow the air out of the stern tube, but failed to wipe up the water thinking it was headed to the bilge. Right now your first step has to be to pump out the water and then determine if the leak persists. If it doesn't all this speculation is irrelevant.

Water
I agree with John F. On my 410 the hose off of the dripless packing gland would overflow causing rust on the aft starboard engine mount and causing water to pond in the pan under the engine. The dealer capped off the tube and there has been no subsequent leaks. There is a lip between the gland and the engine pan which should prevent most water from the gland leaking into the pan if the leak is from the gland itself, even if it is burped. If your problem is not the tube you most likely have a leak in your cooling system in line before your heat exchanger. If the leak was in the heat exchanger you should see green cooling fluid in the pan.
