Greetings all,
I thought I would share my experience and a link to Kohler generators manual since it was helpful to me.

So, with a new V275, I was thrilled I had a kohler generator, but couldn't find the manual after it stopped suddenly the other day.

The story:
I was told to run the generator a little bit with a load every time you're up there, even if only for a few minutes. So, I have been doing that, maybe 3-4 time since I got the new boat. The other night, while in the slip, running the gen with the AC on, she stalled and stopped. I tried to restart it and nothing. So, I shut all the switches down and opened the engine hatch. Error code on the genset said Low Freq, fault. From reading, this also could be from over-loading the generator and having too much load on it.

I found this on the internet, so credit to whomever put it up at atlantis marine.

Reading this and found out how to reset the fault. Once I did this, power disconnect and reset fault via the knob and button on the genset, she started yup again, second attempt. I have a momentary remote switch in the cabin.

So, regardless, I figured someone else would need to look this unit up at one point (or other kohlers) and it would help out.

Nice post and good find on the manual. Those trouble codes can be a PITA!

I subscribe to the school of thought, that if you run the generator often - it'll run well. Do not run it and when you need it - it'll have issues!

For instance, on my 318 I ran it every time we unplugged from shore power and left the dock - until it was back at the dock. Rarely had an issue and had A/C & Heat all day on the boat. Fuel expense for a generator is minimal.

I have to dig in the manual to see what the gallons per hour is on the 4kw unit. I'd be curious to see what a regular load on it would use, for example, overnight with AC. I am sure its in the specs somewhere in that pdf.

(updated)
This is the exact model, now that I looked further. 5EkD low CO model Kohler

And fuel consumption at 100% load is 3.52lph (0.93gph) so good to know if doing an overnight.

Yep - right at a gallon per hour.

On the 318, it pulls from the right tank and due to it, always had to put a few more gallons on that side. On the 268 it was like yours, just the one tank. I never much paid attention to economy on a boat though.

Keep posting more pics - we need to bring this forum back to life!

So, for those playing along at home, my 5EKD Kohler was running ok and it then stalled and threw a "Loss of Coolant" error, which I was able to reset. I checked the fluid levels and all was good. I then called 1-800-Kohler and spoke with the tech support rep and he suggested checking the basket for blockage even though I had water output being produced out the exhaust side of the boat. Sure as heck, shut off the seacock and checked the strainer - some seagrass and I got her reset and started again. He suggested checking it each time I go out, which is a bit much with how tight that brass on brass basket/strainer is to open (vs my old plastic v248 2002 strainer, for say, the AC unit.)

With that I also was referred by Kohler to a local guy who is Kohler certified and works on the Miss Lotta, the local Lake Hopatcong, NJ tour dinner boat (who just had a new 20K Kohler installed which they run almost 24/7 according to the tech. Local tech said he would do tuneups and winterization since my local boat mechanic will probably give me a "We dont work on generators" line, but that expected.

Additionally, I spent the $25 and picked up a new seawater impeller/gasket replacement since they suggest every 10-20 hours or so or wo regular use (it might dry out), and/or yearly you might want to check/change it if you are having cooling issues. So, its a project for another day if needed.

Ok, mission accomplished!

Ordered a new impeller, Kohler match for 5EKD and removed old one (what a mess), got as many pieces as I could and tested ok. I had to utilize someone smaller to get both hands on the housing to get the new lubed up impeller in. Ran and tested with a load for about 30 minutes, so she should be good to go! Pics for your enjoyment.

Can you tell which is the old impeller? lol
