Mine do I am mechanical…not sure with the electronic versions
Disconnected them on the 480CE and never had an issue. Boat was in Florida so they were not necessary.

It would be easy enough to do a test. Disconnect one engine and compare to the other in Oct's cold mornings. I don't think I'd remove them without doing that first.Mine are mechanical also. When I start my boat I see them cycling on and off. I am in the water from late April until late October. If I disconnect them I wonder if it will cause starting/ running issues in the cooler months.
I just removed the harness …not as fun as I had hoped…. I think I peeled every scab off from my AC install……your directions were spot on. Thank-youI just wrote this up and sent it to a friend. So here you go:
Remove three bolted on small wires on the heater (two power, one ground). Unplug air temp sensor on heater (I also took the sensor out and replaced it with a plug - optional). Remove small red power cable at starter (long cable that comes from grid heater on other side of engine). Remove two bolts below the aftercooler bracket, holding on the bracket containing all the grid heater electronics (those bolts may also hold on some unrelated ground wires and/or the check valve from the airsep - just bolt them back on where they were after you remove the grid heater bracket). Unplug the three sensor connectors coming out of heater wiring harness (they will be behind the aftercooler). Then pull it all out. It's all one big system all coupled together.
That one doesn’t look too bad. Both of mine were a charred yucky mess.I just removed the harness …not as fun as I had hoped…. I think I peeled every scab off from my AC install……your directions were spot on. Thank-you
One post fried …that’s all it took to keep it on and super heat the manifold…. even with the engine off.That one doesn’t look too bad. Both of mine were a charred yucky mess.
Hey guys, new 400 owner here posting for the first time. I purchased a 2003 400 Sedan Bridge with the Cummins C Series Diamond 8.3s a few weeks ago. Love the boat and am prepping for end of season service. One question I have is recommendations for antifreeze. Cummins only recommends Fleet Guard ES Compleat, however, I’m in northern Door County, WI and can’t find this anywhere. Are there other acceptable brands?
Order it online or the next time you go to Green Bay go a few miles further to Depere and get it at the Cummins place.Hey guys, new 400 owner here posting for the first time.

Good advice, thanks!Order it online or the next time you go to Green Bay go a few miles further to Depere and get it at the Cummins place.
Any 50-50 ethylene glycol extended life coolant pre-charged with the DCA (if not pre-charged then you will have to add the DCA yourself). Most use the Fleetguard ES Compleat EG. I've used Peak Fleet Charge for the 8 years I've had the boat. Read up on the reason for the DCA and how to use annual replacement of the coolant filters to make sure you continually have the correct amount of DCA.Hey guys, new 400 owner here posting for the first time.

Got it, thanks! I ordered a DCA test kit and am replacing the WF 2071 DCA filters so, I’m assuming that I won’t have to add liquid DCA.

I never understand why anyone would deviate from Cummins recommended products….be it filters, parts or fluids. Yes they cost more but piece of mind I think trumps price…. Plus what would you think if you popped the hatch and saw fram filters ? Yes there are comparable products but I stick with recommended with something that expensive ….might just be meHey guys, new 400 owner here posting for the first time.

So you are saying we all should be using Valvoline Blue and all of us using Rotella T are not being very smart?I never understand why anyone would deviate from Cummins recommended products….be it filters, parts or fluids.

LOL…. I didn’t think you guys actually read this stuff…. Do as I say not as I doSo you are saying we all should be using Valvoline Blue and all of us using Rotella T are not being very smart?

It’s so hard to be humorous on a message board. No inflection in voice our facial expressions to help. Glad you didn’t take my response seriously.LOL…. I didn’t think you guys actually read this stuff…. Do as I say not as I do
Here are two articles on the specs

So here's my issue with the pan heaters that i recently installed this past spring. I don't want to leave them on always in the cooler months (Should I?). Since I have the 250 watt model, if I get to the boat and want to take off how long would it take to heat up the oil to a useful temp?Your motors will start and run fine without the air heaters. What you will notice in colder conditions without the air heaters is a little smoke and diesel exhaust smell. I removed my air heaters 5 years ago and went with pan heaters.
I have no regrets. Earlier this summer we went to Lake Superior and were out at Isle Royale for 11 days on the hook. I didn’t bother running the pan heaters for the few hours per day we ran the gen to keep our batteries up. Under those conditions the pan heaters wouldn’t have helped. Between the cold water and early morning air temps in the low to mid 40’s, the smoke was noticeable until warm up.
Not long for the oil, few hours maybe. The coolant and the block, overnight. It takes a while to warm up 1500 pounds of steel. I leave mine on, an added advantage is the warm engines act as a dehumidifier.So here's my issue with the pan heaters that i recently installed this past spring.
