Official 2003.5-2008 340 Sundancer Thread

What a fun morning. Been fighting the generator on my 2006 340. It would run for 5 mins then shut down. Changed out the impeller, flushed out the exchanger, then when I went to clean the strainer, the cap top broke right off. So now I am at home with the broken top piece, but no part number. Could someone take a look at their cap and tell me what the part number is? My piece is 2 3/4" diameter without the ears. I know it is a Groco, just need to know which cap.
My boat as the perko brand and is different. But if you got to https://ownersclub.searay.com/ and sign up and register your engine serial numbers (or maybe it was the hull id) you can then get most of the manuals in pdf form. I use my parts manual all the time.....unfortunately.
 
I think my shaft seals are leaking, seems to be something wet under that blue colored boot where the shaft exits the boat, anybody seen this at all?
Yep. Just replaced my shaft seals in February. They come with a spare. If you look between the boot and the transmission you may see another collar. In that collar is another seal that can be slid down into place after cutting out the old one. If that collar is not there, then this process has already been done (or maybe yours didn't come with a spare, but they usually do). If no spare, you'll have to have to pull the shafts in order to replace. Cost me about $4,000 after the dock haul and storage fees (that part was around $600 for a week of storage).
 
Webasto A/C shut down with an E1 error code. Looks like it may be a clogged system or over pressurizing by google searching.

Has anyone flushed the system and how did you do it? I searched here but came up empty?

Thanks

Sometimes the thru hull gets clogged and prevents the pump from picking up water. If you have a shop vac you can use a funnel and put it in your strainer ...stick the shop vac hose into the funnel and use it to blow and that might clear it. Open and close the seacock so it blows through your system too.

I would try this before you do a full system flush. I personally use a Seaflush to do both tasks, but a funnel should also work. If you go to seaFlush.com there are videos about how to flush as well as use a shop vac to blow out potential clogs. A funnel should be a sufficient compromise for the shop vac side of this process.

Agree with Kevin. I too use Seaflush. Though if the system is priming enough to pull the fluid, you can stick a hose sprayer on the end of one of the pipes. Shut off your sea cock, pull the hose from there and spray through all to ensure you flush all lines including the sea strainer. Then use Seaflush and pull some barnacle buster or the like into the system and let it sit for about an hour or more, then flush with freshwater again. I do this a few times a year.
 
I paid a guy who only works on generators to look at mine. He said my carb was bad. It is a 2004 Kohler 5E(Non Led display) with 180hrs. Paid him to replace the carb, plug, fuel filter, oil and go over it last weekend. She ran like a clock all weekend. Sorry I do not know the cap part number.

thank you

unfortunately I’ve already done those things and still the problem persists for mine
 
I did this on my 2003 with Simrad. You have to replace the wiring harness under the gauges to get the smartcraft and new Simrad (and other brands from what I understand) and the original gauges to all work together. You have to set the smartcraft and the new device (Simrad) id correctly too, ie 1, 2, etc...And this will transfer your smartcraft settings to the new device as well. I contacted Mercury and they assisted with the proper wiring harness for my boat.

Thanks, I will give them a call. Maybe they can also help me get my gas gauges reading somewhere close to correct.
 
Guys wanted to share this upgrade I did over the weekend. Never had anything for the space under the port cockpit seat and I always need more fridge/freezer space, so I got this Alpicool C15 fridge/freezer. Ran a 12v outlet from the house battery bank. It seems it was made for this spot.

Nice boat pic. What sun fly are you using?

Just curious...I had a similar, not the same issue....but have you done the basics for the fuel filters? Mine has a fuel/water separator and then a hard inline filter just before going into the generator. I'd replace both of those. And when you do, fill the fuel/water separator with SeaFoam so you can get a good cleaning through the carb and lines/valves too. Doing this fixed my problem, but mine would stay running, just ran like crap.

You may want try burping the coolant system by opening the bleeder valve. Skip to KevinC's post below for more detail. The tech said an air bubble can develop causing the overheat sensor to trip. He said 9 of 10 times when he gives that direction over the phone he does not hear back. I tried that first but it did not solve the issue. Good luck, we all need our AC for sure right now.

LOL ..yes the light! Good eye! Thanks for reminding me. I need to connect those with heatshrink connections properly. Also so far as running 12v to panel ..this is fine for now, but good idea. My boat stays in year round so if it’s not on the hook, it’s plugged in at the dock. I’m scrambling getting ready for an 18 day trip out coming up here next week, so I’m going with this for now :)
You may want try burping the coolant system. Take the cap off, run it until fluid overflows, shutdown and top back off. Makes a mess so have rags handy.

There was a discussion about this here:
http://www.clubsearay.com/index.php?threads/kohler-5e-generator-help.93812/
and @mnm99 added a bleeder for the system.

It did require drilling and taping a new hole.

Can those who have connected an aux input to their 2004 stock Clarion head unit tell me if these two rcas are the input?

From recollection I believe there’s only one aux input and that’s likely it. Try it while it’s still out. I put a Bluetooth module on mine a couple of years ago. Was a great upgrade.

Thanks ..I made my own. It’s just an 8x8 sail shade (maybe 7.5x7.5) from Wayfair and two boat hooks stuck in taylormade rod holders I installed aft. It works great. There was a thread I started all about this with others’ ideas as well. Here’s the post of what I ended up doing, but check out the whole thread. There are lots of good ideas and installs here.

ok so i been asking some questions and just want to throw this out there. i did my elbows and manifolds 2 seasons ago and thought i was all good to go. then i ran my boat on a big trip. 107 miles each way. i blew a transmission cooler. i didnt even know that was something that should be replaced. then i found out we have oil coolers also. i can only imagine an oil cooler letting go and flooding a motor with sea water from the bottom up. anyway just thought i would tell u guys replace your transmission coolers and oil coolers. relatively inexpensive and can save you big time down the road. i live on long island in new york. i live in massapequa. my trip was from massapequa east. 3 nights in westhampton beach, then on to montauk for 2 nights, then across to block island for another 2 nights and then all the way back home. amazing trip. luckily i got a shaft seal and a tranny cooler replaced in montauk. rode the inside through the bays and through shinnecock locks and up around shelter island. such a beautiful ride.

M Prod, thanks for the quick response. To take that pic I did not pull the head-unit. Pulled the circuit breaker panel and stuck my iPhone in the opening and started snapping pics until I got one that showed the RCAs. Question on placement of your Bluetooth Module/Dongle. Did you place it behind the head-unit/circuit breaker panel inside the cavity? Or did you run the aux cable outside and then attach? The Aux is on the head unit above the breaker panel not the unit above the galley? The Bluetooth adapter I have needs 12v so I need to figure out powering it. Ordered the RCA to 3.5mm adapter and plan on plugging in Friday evening for sound test. Plan is to get it working then figure out the cleanest permanent installation. Thanks in advance for any advice.
