No worries. I should have dug out the manual and got the proper model number before I posted. We've got about a 10 hour run tomorrow in triple digit "feels like" temps, with two pampered cats on board. I had to get this sucker going and was a bit panicked. The switch is on it's way to me...

OK, I'm aware of the two circuits, but didn't think about flow in closed side being an issue. That'd be a first for me. I do have it narrowed down now. I disconnected the pressure sensor on the heat exchanger and it runs without the error. I found one locally and the Admiral is on a parts...

Yea, I noticed that 8kw spec once I dug in. Not sure where I got 5KW from. I'll blame the admiral for that one. I had to step away from this to try to find an alternator for the main engine but I'll be digging into the manual here shortly.

The generator never overheated. It won't run long enough to even get hot. The last time it was used, it was shut down normally, not by a sensor. I did pull one of the endcaps and there was one blade of an impeller there. I tried again with the same result once it was removed. The heat...

There is actually a separate code for engine overtemp. I believe this is a flow sensor in the heat exchanger. The troubleshooting for the code is to check the impeller and water flow. My last two boats (both Hatts) had gauges for the genset, but this Mainship does not. I'll have to check...

I just pulled the manual out and will look for the schematic. Oil level is OK. The pump is belt driven. Tension seems fine. It's pumping a lot of water, no squealing. I'll get a photo of the diagram if I can't figure it out from that myself. Thanks, -Ed G.

EDIT: Model number is Model is 8-E32OZD This generator will be the death of me. So I started it to warm it up for a simple oil change. After about 90 seconds it quit with the LOC code on the display. Did some research, looks like the most common cause is low water flow, even though it can...

I came here after the Hatteras I was a partner in was taken by Irma. We ran it like a trawler most of the time, but it wasn't one, and her systems and propulsion didn't resemble anything common here, so a lot of the info here didn't apply. Now, we have a Mainship, an actual trawler of sorts...

You've got that right for sure! :banghead::banghead::banghead: I bought a pump and some hose to hookup to the overflow line. I couldn't blow through it, so I'm not sure I get get fluid through it without releasing the cap. I'll know one way or another shortly. I'm going to try and get...

Do you by chance have measurements for placement of the deck plate? I'm going to try to get behind the genset and pop the rear cover off before I commit to cutting into the deck, but I'm not hopeful that I'll be able to get back there. Thanks, -Ed G.

The Admiral has stated a hard "No" to that suggestion, but then, she doesn't do the maintenance..... Ha! I'll let you know if I survive it! I figured "while you're in there" I'd replace the belts too. Turns out someone in the past had taken off the alternator bracket and couldn't get it...

Those that have this model know that the generator is mounted under the cockpit. There is no clearance on top to get to the coolant tank cap. I'm replacing the heat exchanger (also a frustrating part to get too) and will need to somehow fill this tank again. Short of un-installing the...

We're moving our new-to-us 2005 MS 400 to Stuart for hurricane season storage. After a 12+ hour day 1 run, I was checking the ER for day 2 and found that three of the 6 screws holding the back plate on had lost their heads and the pump had sprayed water everywhere. I'm thinking no problem, we...
