I fired up my generator while anchored and wasn’t getting any water through the generator so it shut down on over temp. The sea clock was open and strainer was clean. We decided to not do any further testing and leave it for next weekend. Any suggestions

Next step would be to check the impeller.
Then…If im not mistaken this model has a coupler that transfer movement to raw water pump. It breaks sometimes so that would be the next item to check.

Two things. Try burping the sea strainer first by loosening the lid enough for water to come out and then tighten again. Second would be new impeller. The Kit from Kohler costs $35 and takes about 10 minutes to swap out. Just know that if you are missing impeller fins when you take the old one out you need to find all those pieces in the downstream pipe before installing the new one. They'll cause blockages. The downstream pipe has a few kinks in it which is helpful to catch any bits that broke off. Also, when you buy a new kit, buy two and have one on hand for next time.

Mine overheated and I checked the sea strainer and the impeller and the strainer was clear and the impeller was good. So with the strainer opened, I opened the seacock and water was barely trickling out. Debris had clogged the intake strainer under the boat. I had a power plunger with a sink attachment that I was able to fit over the strainer opening, then opened the seacock all the way and forced the debris out through the bottom. Afterwards, water was gushing out of the strainer. That fixed my problem.

I had an impeller failure a couple of seasons ago...the impeller had fell apart and bits of it went up stream into the cooling tube for the fuel system. Of course in order the find the blockage I had to disassemble the whole system including the fuel system. I ended up replacing those parts and the heat exchanger. My replacement was shipped incorrect due to my inaccuracy but they were great to work with and the problem was solved. Note the company name on the part.  |

Hey MyPleasure, I think that you are trying to tell us something with those building plans! What project are you working on!?!

Here’s the latest and still need help. I replaced the strainer and removed some hoses at the generator. I have water pressure and good flow at the hose that looks like it enters the exhaust stream but when I connect again to the exhaust manifold, I have no water in my exhaust stream. Here’s where I got to. Any suggestions

'  H I have water pressure and flow after the heat exchanger (bottom hose) and into the top 90 degrees fitting which I think is into the exhaust pipe but nothing in t he exhaust. I let it run for about 45 seconds and only exhaust gas coming out hull, no water in the exhaust so i Shut it down again |

Yes, get out broken pieces of impeller blades out of system, back flush with garden hose with pump cover off! |

One thing you can do to help find the loose impeller fins is to remove your anode from the heat exchanger, then run the generator for a short time. Do it in bursts so as not to over heat it. The water flow often will eject the broken impeller fins out of the hole where the anode mounts.
If this doesn't work, you may need to removed one or more hoses going to or from the heat exchanger to find any lodged broken fins. They could also be stuck in any part of the hoses where a bend occurs.
If people that replaced an impeller don't find all of the missing impeller fins each time the impeller is replaced, sooner or later you will have this problem.
Could also be a stuck thermostat, so don't rule that out.

Pull the hose off of the 90 degree elbow at the top of your exhaust. If it has good water flow there, remove the metal 90 degree fitting and check to see if it's clear. That is the hose that supplies water to your exhaust, so if it is clear and the 90 degree elbow is clear, there is an obstruction in the exhaust manifold preventing water flow. For future reference, you can disconnect that hose at your exhaust and the hose between the engine and water pump and use a water hose to backflush water through the generator to flush out impeller pieces.
