40 sedan bridge forum

Yeah, that's what I was afraid of. I guess I have winter project #42...
At least I can claim no more visitors this season. It's our first with the boat.

With regards to sending the sinks overboard, is there a reason to forgo using a "trap" by looping the drain? I suppose it's not a big deal but...spiders, bugs, etc...
I did consider that. was worried about food particles getting clogged in there. So I just keep a plug in the sink drain when not using the sink.
 
Anyone have information on the gel coat for our boats? I need to do some minor scratch repiar
Yes. Buy part number A551470k, Sea Ray Artic White 94-03, from Spectrum Color. This part number is for the 2 oz patch paste. You can do quite a few nicks and gouges with this amount.
 
There was a separate thread on this but I can't find it as easy with the new forum software, so I will put it here. I finally got around to resealing the three windows of my windshield. I used the following steps after buying 55' of the trim.

1. Pull off old trim
2. Clean and surgically reseal where needed. Note that the old sealant is very dry and crumbly. You can get carried away cleaning out more of the old stuff than you need to
3. Install new seal. It was easy to push in once I figured it out. Push the top edge of the insert into the channel then push down and in to roll the bottom edge of the insert into the channel.
4. Run sealant under and then over each joined edge.
5. Run sealant under the edge of the trim to glue it to the window. This will help prevent the shrinking (I hope).

I used OSI Quad Max sealant in black.

I have a bunch of pictures on my phone and on the Cloud to upload but I have no idea how to get a picture into a thread with this new website software. I used to be able to just drop them in.
 
I think I figured out how to imbed a picture. First pic is with the old trim removed. Second is the new trim installed.

Has Anyone changed the temp gauges to digital? Over the last month I noticed the starboard gauge going to 200. I changed the impeller (was perfect condition) and I cleaned out the transmission cooler which had some but not much obstruction. When I was running back from AC I went down and pulled open the hatches, both motors were purring along at 180 on the motor but yet still showed 195ish on the gauges.
Couple days later running it was showing 200 again and then 185 on the way home. Being the motors both show 180 the reliability of the gauges is in question (as they always are). But for piece of mind so I stop wondering if the motor is running hot I would prefer a more reliable dash gauge.
 
Ok Bill...do tell us how to imbed pics. I wish we could still see the boat details, I liked knowing whether or not I was looking at a diesel boat or a gasser as well as what year.
 
One other thing on window seal. I reused the best of what I removed to replace the severely shrunk side window trim. Before and after pictures:

I have a temp problem with one of my gas engines. My starboard engine has a constant temp of 165 deg in idle and up to about 2000rpm, with cruising rpm's of about 3000rpm the temp goes up to 175 and a lot of steam comes out of the exhaust. I changed out the impellor, no change (the old one was in good condition). I checked the trap by the oil cooler raw water inlet side and there is no obstruction. What else could it be?

For comparison purposes, what is the temp of the Port engine at those RPMs?
 
Given your location, if the impeller you removed had all of its vanes in tact, very likely a fouled inlet grate or dirty heat exchanger with the symptoms you describe.
 
As Frank stated, it's likely something it restricting flow. I had a similar situation happen and this past weekend i was able to get in the water at a protected anchorage and use a brush and pole to brush off the intake grate. I noticed my temp drop about 5 degrees. So that grate must have been a bit fouled up on mine.
 
Frank, if you're still out there monitoring this thread (or if anyone else knows), I have a question. It's my understanding that the t-Stats on my 3116 engines are "supposed" to be 190 tstats. However, my temp gauges show just a hair over 180. So I'm wondering if somewhere along the line someone swapped the 190s with 180s. I understand that gives more of a window for error, but that's not what the engines were designed for, right? If the folks who engineered the engine designed it to run optimally at 190, then I think I should put 190s in.

I was planning to do a coolant flush and change this winter lay-up and also change the T-stats. But I'm not sure if I should get 180s or 190s. Any guidance on this?
 
Caterpillar makes both thermostats for the 3116 engines.

The warmer the engine runs, the more complete the combustion process. Cat's thinking is that the higher temp thermostats, the lower the soot and emissions. You won't find any difference in your GPH and, honestly, I can't tell much difference in sooting or smoke since these engines have an extremely efficient injection system and are very clean burning anyway.

As far as temperatures and "window for error" is concerned, The 3116 has ample cooling capacity. I've run 194˚ thermostats for about 10 years and I have never seen the temperatures approach over heating. I am in warm salt water and we get crud in the heat exchangers here. The Cummins guys clean heat exchangers and after coolers about every 18 months….I clean mine every 5 years; I get no temperature rise as I approach the time to descale the coolers, and I never see temps that worry me.

This one is kind of a flip the coin for me….I can't get excited about 180˚ vs 194˚. If you get some smoke and sooting, then try the 180˚'s; if you are happy with what you have then don't fix what ain't broke.

Sorry…..that isn't my usual cut and dried answer, but it is what it is.

I'll check the inlets. Just had my bottom paint done and the inlets looked fine though...
I'll check into the heat exchanges as well and maybe the thermostat.
Thanks for your feedback

I had a similar problem with steam coming out of my port engine. It ended up being bad fuel, mainly moisture in the fuel.....which diesel engines do not like. I ran the tanks to almost empty, changed all the filters, including the fuel separators, filled the tanks half way up and ran that fuel out before filling up completely (which I rarely do because of weight). The problem fixed itself. I am not a diesel guy and cannot tell you if this was the fix.....it just fixed my problem. Good luck.
 
I will be checking out a 2000 400DB later this week. Has the Cat T3116TA engines with about 900 hours. Has the two state room layout. Is there anything in particular that I should look out for?

How much HP does the 3116s put out? There were 2 configurations, 300 HP and 350 HP. I have the 350HP 3116s and that's just enough power. I wouldn't want to have any less than that. Just my preference.

If you decide to move forward on it, just make sure you have a good marine surveyor who knows how to use a sounding hammer to check for any moisture issues. Moisture meters don't tell the whole story on these hulls.

They are great boats and we LOVE ours. Good luck with your search.
 
I looked a 400 sedan bridge today. Looked in the floor compartment in the 2nd stateroom. Had some water in it. All the other bilges / compartments were dry. Any thoughts on the cause or what to check?
