Here is what I'm chasing. I get this dirty sooty mess in the bilge. Initially I though it was just a transom leak, and re-calked the seam. After that was fixed, I noticed rusty staining on the exhaust.

I would just bite the bullet and spend the $300 to cut out and replace the exhaust hose (to make my life easy)....but I blew all my money on 8" orange fenders....:grin:

Well, I found my leak Paul, after cleaning up the area really well. Time to replace the small exhaust hose and clamps. Parts manual says it 3" inside diameter. Now to find someone who sells it long enough (which I haven't measured yet). Sorry for the crappy cell phone picture. Should I do the blue hose here too? IMG_2577.jpg

What hose is that? I'm not sure 3" ID exists anywhere on a 400

Its the small exhaust hose out of the top of the muffler that runs parallel to the big exhaust hose and exits to the starboard side right next to the muffler exhaust. Its the exhaust path when running at idle and low rpm and is where the water shoots out when you fire up the engines. The parts manual says its 3", but I will measure.

My first thought would be smaller, but maybe. I'm with Mark on this, it's water cooled.
 
Just measured it. Looks a lot bigger than 3". I measured the circumference of the pipe and its 9 5/8". So thats a 3" inside diameter. I need a good 7 feet for that run. So I will buy an 8' length

Ok, good idea, I will clip one and see which one is bad.

I just did that, I cut the wire from one pump, still the same problem,so I said easy have to be the other pump, I cut the wire in the other and the same issue, breaker trips with either pump.
What can it be?
 
You have a clog after the pumps. We had a wad of paper towel (nasty guests) stuck at the entrance to the holding tank. If you can run a snake through the line, that should tell you were the clog is. Just recently we had to replace the hose completely form the pumps to the tank. They were filled with calcium deposits and the calcium broke apart, stopping flow and making breaker trip.

Ok, i agree with you, have to be after the Pumps, that will be easier, because disassembly the pumps is very difficult on that tiny space.

I am going to try that, thank you very much bahamabreisus...

What kind of snake? Just regular manual from Home Depot?

A snake will not help here. If you have a clog
, it is at the duckbill......and all you'll do is destroy it.

Are you saying with both pumps cut, you are still tripping the breaker? If I remember correct you were seeing a wide swing in amps as you reset the breaker...if that be the case, your problem sounds like a shorted wire between the pump and breaker. You can test this with a continuity or ohm meter.

Not saying snake through the pump, start after the pump

Yes I believe you mean is to use the snake after the "Y" to the Holding tank
, for what I see in the manual parts there is not duckbill on that.

What I did was I clip one pump and try the breaker and it trip, then I disconnect that and connected the other one and also trip , so I believe the clog should be after the Pumps , I agree with bahamabreisus, the only way to introduce the snake is removing the "Y" and from there to the holding tank

With the 2 pumps cut, breaker is dead, it does not trip
But if when I connect either one or the other, it trips.
