That seems like a tricky one. There's not a lot going on in that area. Strut bolts is about it (unlabelled + signs with boxes around them, I think), but it sounds like an awful lot of water for that to be the cause. I guess if was considerably loose it could. Any vibration?Okay you leak hunters, see if you can help out in this one. 2004 420 SB always had been a dry boat same owner now for three plus years.
There is water collecting in the aft pump well via the channel on Strd side of center walk. We sponge dried a few gallons out of the well, then tracked back and found water had collected in the underwater exhaust area out board of rudder shaft well. Dried all of that area then went for a run. All was dry until we came off of plane and found just as much water in those areas. I sat back there behind the genny with a flash light and watched as we went back on plane then back off, get a bunch of water sloshing to the stern from under the genny into the rudder shaft box and then into the exhaust box. Come off plane and it drains forward and eventually ends up in the pump box.
We will pull the batteries, AC freshwater pump and a few other odds and ends and pull the floor up to see where the water may be coming from. Only seems to come in while under way not just sitting. I’m thinking possibly the strut bolts may be leaking thru?
Any ideas anyone?
Thanks

I spent 30 minutes inspecting the entire engine room while under way this after noon from idle speed to wot. I think my hearing is coming back finally. I saw no dripping or spray from either exhaust system. Genny was not running. I think it is only leaking at speed when the bow is up. Harold is pulling the starboard floor forward of the genny and we will take it for another run and be able to see where the water is coming from. It will serve a dual purpose as there is a mess under there from an unfortunate past sewage situationThat seems like a tricky one. There's not a lot going on in that area.

Could it be a generator muffler hose off or cracked? Rusted generator muffler? Rusted generator heat exchanger (but I guess that wouldn't be affected by on-plane / off-plane), cracked or loose generator raw water hose? Cracked or loose underwater exhaust hose?
Is it accumulating only on the starboard side? Not a lot of hoses down low back there...

Generator heat exchanger is on the port side of the generator, I think, but I suppose water could make its way over to the other side.
Rusty - My bet is the deck to hull joint. I think you will find the rub rail in the aft areas of the boat pretty much wetted all of the time when running and coming off plane. That joint is also like a roof leak on a house in that the leak location may be different than where it shows.

I had exact same boat, and exact same mysterious water in aft pump well. One year when I put the boat in drydock (inside a building) I vacuumed the water out and it reappeared a few weeks later. I chalked that up to water that had been vacuum held in one of the pump hoses eventually let loose. I also had mysterious water under port engine that I could never find source. I don't own the boat anymore but I'm still very curious where it was coming from.Okay you leak hunters, see if you can help out in this one. 2004 420 SB always had been a dry boat same owner now for three plus years.

Replaced with the isotherm 49 drawer. Had to trim about 1/2 inch on the side to get it in. Much nicer fit and finish plus way quieter than the old one. The hum from the old fridge would drive me nuts when relaxing on the salon sofa. It was louder then the gen.Does anyone know of an appropriate sized replacement fridge for the port cockpit fridge? The old black one is looking pretty tattered.
I had to replace mine when I bought the boat. Got a new one in Plymouth before leaving. I am 90% sure it was this one (not at the boat, documentation not near me, double-check dimensions!) :Does anyone know of an appropriate sized replacement fridge for the port cockpit fridge?

I got a Dometic two years ago that turns into only a refrigerator(has a removable freezer) Had to enlarge hole maybe 1/2 inch--has been working greatI am in the process of a recon on my original cockpit refer that still works. If any of you that have removed your old refer
have good hinge pin brackets I would be happy to purchase them.
I believe you have to remove the exhaust pipe. I had both pipes out the winter of 2018-2019 to replace all the sanitation lines and I almost had the hot water heater replaced then, but didn't do it. I should have.My water heater died and I'm having a heck of a time figuring out how to get it out and a replacement in there. Anybody done this before and have any tips on the best way to replace it?
I'm putting in an Isotemp SPA 40 to replace it and I want to orient it sideways to make replacing heating elements on it easier than the Attwood in there now oriented forward.
BTW That Attwood is a horrible design and I can't understand why Sea Ray would put a unit in that has to be removed to change the heating element.
Thanks!
How hard is it to remove the exhaust tube and can you do it with the boat in the water?
It sounds to me, if your holding tank keeps filling up, that the problem is at the toilet, not the vacuum pump. I would check to make sure the flush lever is fully returning to the closed position. If it isn't, two things will happen. The ball valve won't seal so the vacuum pump will continue to pull air and fluid from the bowl. Also, the water valve on a cam in the lever will not close so water will continue to run into the bowl. This would fill your tank. Some rebuild kit for that set of problems!Jeez, i hope the exhaust tube doesn't leak. My WH is ok for now. I just replaced the dripping pressure relief valve. There is some corrosion at the base but not too bad yet. Maybe next year i'll get to it. Good luck with your's and keep us posted if it leaks when the exhaust tube is removed.
I do, however, need to fix my stbd head. There is some sort of leak, where it effectively continues to fill my holding tank if i don't shut the breaker off. I have read there is some sort of gasket/seal rebuild kit at the pressure tank, which is right by the water heater. It would seem i need to also remove the exhaust tube to work on it.
Has anyone had to do this rebuild? I suppose i have been fortunate that in my 10 years of cruising i have never had to get too dirty with head work, minus kid clogs that could be handled at the toilet... It was only a matter of time i suppose....
