Sorry, I should have been more clear...this is the actual portion of the assembly that I'm looking for:

I'm more curious as to how you acquired this schematic, if you don't mind me asking? - Todd

I believe its from the wiring diagrams. Here are the three documents I have.

Ok, this weekend I had a survey on a 92 model with Cummins diesel.
The boat was not near what I was hoping for.
Since the owner is in a wheelchair he did`nt cover her up for the winter, so the inside was very wet.

If the owner is right, the water under the floor comes from a dead greywater-pump, followed by a dead bilge pump due to dead batteries. He said he had some help to clean inside the boat, and they put the water in the shower drain. I find that a bit strange, because I believe it is about 50 liters water in there.

My fear is that he is partially right, but that most of the water comes from leaks in the railingsupport. The picture is from the port cabinet in front, and that`s an easy fix. If the supports behind the bathroom and kitchen cabinets leaks as well, I have no idea how to reach it.

I haven`t given her up yet, because I really like this model and it is quite rare in Norway. If I belive I can make her dry, and I get a good deal, this could still happen.

BV,
I can't tell if the shower sump box is full up to it's overflow line. It's overflow line runs to the bilge under steps. So, if someone used a lot of water to clean boat and then dumped it in shower it would fill sump collection box, then overflow in bilge and fill that center locker if batteries were dead. I noticed the water has not stained the carpet or the fiberglass in storage compartment so its not a long term leak that caused stains, so owner could be telling the truth. I would get a fresh battery and hook it up in boat, both pumps should come on instantly. The house battery bank will work with one battery, I believe you want to hook up to the battery lugs that are the furthest aft. Of course make sure main battery switches are n on position. If both pumps come on you should be ok but I would do more investigating and pour water in the shower drain several times and watch collection sump fill up and look to see if that pump and float works.
Let us know how that goes. It still sounds like you have other potential leaks that need to be investigated.

Another note: It's interesting you have an insulated HAVC line in center locker running forward. Where does it go? My boat has two AC units, one under salon couch that feeds air to port side behind refrigerator to outlet by coffee machine and the other on starboard side running behind the mirrored wall to outlet by couch. Make sure someone didn't run that line to the front AC units diverter box because that AC unit died. The front AC unit is under the bed and feeds front cabin, side cabin, and bathroom. Both AC should work, if not, very costly to repair.

He replaced the batteries before I came, but the pumps didnt kick in. Maybe they broke down from beeing drowned in water a couple of months? Anyway, the owner told me he would get his helpers to dry it up and replace the pumps at his cost. He had the batteries replaced the minute he descovered they were frozen in pieces, so I don’t think he’s trying to trick me.

In Norway people rare use AC, so in this case it is replaced with a Eberspächer air heater. It warms up all cabins, included two outlets in cockpit. I’m not worried about that as soon as it dryes up, but I guess the insulation must be replaced.

The owner told me he would dry the boat and use an air dryer, so I’m planning a new survey May 1. I’ll keep you updated.

It's nice of him to replace the pumps and floats. Make sure the main battery disconnects are "ON" or pumps may not turn on. Mine is behind the large bench seat in storage compartment by entry way on trasome of boat. Those pumps should work even if submerged in water for a while but if water froze with pumps submerged they could have been damaged. I assume the water was collected in locker area recently, i.e. after the weather warmed up to above freezing. For safety all bilge pumps are wired such that even if all the breakers in main disrtibution panel in salon are off, they will be live in the event a boat takes on water whilest moored at marina, but I am not sure if main disconnect is switched to off. I think even the shower sump is wired this way. Others may confirm. Also check the main circuit breakers in engine compartment for a tripped breaker, red push buttons, note in the picture one labled "Sump" and one labled "FW Emergency Pump".

These fixes are pretty straightforward and not difficult. Repair or replace pumps as needed. Water vac as much water as possible out of the bilges and enclosed spaces. Spray down with a bio agent like natures miracle that will attack organic matter in carpet and surfaces and eliminate it. You don't want mildew or mold in the boat. Use a portable dehumidifier and fans to quickly as possible dry all areas. Make sure to empty dehumidifier or place it over galley sink and direct water into it for overboard discharge. Then address re bedding your deck rail stanchions so no more water will enter cabin. Not a deal killer as long as you avoid mold and mildew.

Getting pumped.....last weekend I installed both FOX digital gateways in my 400. This week, the 2000 NMEA backbone goes in and installation of the new Garmin displays......will post photos when done. Then on to the installation of all new cockpit interior.

Sorry for the poor photography.

no luck finding new series V switches so the old ones will have to do till I find some...apparently a supply chain shortage in effect.

 

[BVegard]

Thanks for tips and support guys. I`m a bit more positive now. Looking forward to next weekend to see the owner has dryed her up, and oil change on both engines + fueltank inspection. If all this ok, I guess we`ll make a deal.

Just curious of Norway have those crazy high "luxury" taxes on power boats like some of the European countries?

I think we used to have some kind of hp-fee for new boats, but I think it was removed when the conservatives won the election. That beeing said, we do have high taxes in general, but thats the price you pay for free schools and health care.

It can not be compared to socialism if anyone believe that. I saw a interview before the your election in november with the qoute «we dont want to be like the socialist countries in Europe, as for example Norway or Switzerland.»
My theory is that people who believe in this dont know what socialism is, or where Europe are.

Sorry for getting carried away, but there is a lot of ignoranse and misconceptions out there.

Yesterday my son and I spent the afternoon installing a new 9.1 cu. ft. Nova Kool refrigerator. We had to remove the sliding door, and it was a tight fit between the helm, and companion seats, but a pretty easy swap out.

Over the winter we replaced the salon floor and carpet, the forward search light, the cockpit side panels, and the rollers on the sliding door all using advice found in this group. I thank you all for your input.

Now we are getting ready to take on our last project before the boat is put back in the water and that is to replace the manifolds and risers. Does anyone have any tips or tricks?

Use some threaded rod the same size/pitch as the manifold bolts about 3/4” longer than the bolts WITH a slot cut in the end. Pull 3 bolts and screw in the rod pieces. Then, pull remaining manifold bolts, get in a good position to lift and slide manifold off. Install new ones snug up the bolts, unscrew the rod pieces, and torque properly.

FYI- make sure that you can handle the weight in the position you’re in. Good luck

Use OEM parts.
You have two choices, the ceramic coated or the E coated.
I buy the ceramic but, believe the E coated are fine..
Replace the elbows and gaskets every 5 years without fail.
Replace the manifolds every 10 years even if cooled with antifreeze.
Check the mounting surfaces are flat, OEM are normally good.
Do not remove the “paint” on the gasket surface, the “coating” is what we’re paying for.

Nuwave Marine has good prices.

Also, on my 10 year replacement plan is the oil, transmission and main heat exchanger. For these I recommend aftermarket parts from Lenco Coolers.
OEM quality at much more reasonable prices.

Admittedly, I could be over-doing-it a bit on this schedule but, the cooling system is the biggest killer of gas powered boats...and I’m keeping my boat.

Ok, this weekend I had a survey on a 92 model with Cummins diesel.
The boat was not near what I was hoping for.
Since the owner is in a wheelchair he did`nt cover her up for the winter, so the inside was very wet.

Well, I'll play Devil's Advocate on this one. First, the bilge pumps may not have activated even with new batteries because the switch had become faulty over the years. But it's more likely that they activated for a while and pumped continuously until the motors burned up. It happens a lot - don't ask me how I know. In this case, the batteries went dead because of something else. Pumps usually burn up before they drain batteries.

But something still doesn't smell right about this - and it isn't the mold and mildew, but that's likely coming. First, it seems to me that 50L of water/cleaner is a damn lot to use to clean the inside of the boat. Second, why would the "helpers" pour it down the shower drain rather than just pour it over the side. Third, that water looks damn clear to be cleaning water, esp since there seems to be no trace of dirt that settled. Fourth, the water stains in the (port?) locker sure didn't come from the shower drain.

Also, I'd be really sure that the stringers haven't gotten wet inside. Make sure your surveyor measures moisture level with a moisture meter and also "sounds" the stringers thoroughly with a hammer to look for moisture / rotting in the stringers. If there is moisture in the stringers, that's big bucks and/or hard work. And those stringers look mighty clean for a 1994 boat.

Was the vessel in the water or on the hard during the winter?

What did the surveyor say specifically about the water? I'd believe him more readily than I would the current owner.

Anyway, that's my 2 cents. Good luck.

Thanks for good advice and theories, I think you are on the right track. I was on a new survey this weekend, and I got some answers and maybe some new questions. First of all, the water was gone, his socalled helpers had bin there to clean up. A dehumidifier had bin used since last survey, so the smell was much better. Still a way to go, but my neighbour works with car care, so with a carpet cleaner and ozone treatment she`ll be allright.

The pumps still didn`t work, so I guess they must be replaced. The owner said he`ll have it fixed, but since he is in a wheelchair I don`t trust his helpers. I think they`ve done a shitty job in cleaning and caretaking, and just drained the man for cash as he couldn`t control control what they were supposed to do.

The stringers seemed good condition both by looks and soundcheck.

I checked the deck rail stanchions behind the cabinet in the bathroom and they looked good, hopefully the rest is ok as well.

So how did 50 liters of water end up in there? Not the deck rail stanchions and not from water in the shower drain.
As I wrote in my first post, the boat was not covered with tarpaulin( thank you Google translate) this winter. The boat is in the owners backyard, and I think she has a bad angle so the water found its way in places it normally wouldn`t do. She was covered in 10-12 inches of snow, so if it front deck or the canvas melted and found its way in, i think that`s the answer.

They say love makes blind, so to sum up I am now the new owner. With som TLC I think she`ll be good.

By the way, we changed oil and started her up and the motors ran perfectly.

There was a forum post about sellers vs buyers doing repair work and ensuring the work was done correctly; I'm in the camp that the price gets negotiated downward for repairs and findings then I or my mechanics do the work. Yes I've been burned a couple of times; the work wasn't done at delivery which is too late or done in a shabby manner.
