    Good video of all the maintenance items, this is on the 7.3e but close enough.

    I was running the Generator at the dock and it shut down with a LOC. I checked the strainer and wasn’t really any concern. Instead of going right for the impeller I checked the flow of water coming in with the strainer cup off, barely nothing. I then took the hose off and used a hangar to try and clear out the valve and then blew some air through (was very restricted by mouth). I have a stream now but not as much as I would think there should be. I know the diameter of the ball valve isn’t that big, but I should have a good amount of water coming in correct?

    Lots of it, you might have a blocked thruhull, mine is 3/4"

    I’m going out for dinner Saturday night, hopefully the run can clear it. If I can get back there tonight or tomorrow I’ll try to blow it out with a shop vac. If that doesn’t work I’ll unscrew the valve and see if I can see anything.

    You might have a strainer on the bottom over the thru-hull inlet that has picked up some weed or some garbage. I would not unscrew the valve if you are in the water!. Attach a piece of hose to it that is above the waterline, open the valve and use a rod to poke down through it.

    @Grahamu I’m pretty sure the inlet for my generator looks like the pic below. My AC inlet has a strainer on it.

    Yes the opening pointing forward to help force the water up into the thruhull when underway.

    @Grahamu I’m sorry! I had to go against your word. I tried the shop vac, heard bubbles but nothing, the flow actually stopped after I did that. I tried the hanger again with no luck. I didn’t have two wrench big enough to remove the fitting from the valve so I went for it. Removed the valve and it was stuffed with seaweed, no water at all. Once it was removed all was good. The valve was surprisingly easy to put back on with the water coming in. I had plugs ready if things got out of hand.

    I wouldn’t have been able to sleep if I didn’t work on it tonight! 😅

    @aero3113 you took that valve off with the boat in the water???
  • aero3113aero3113 Member Posts: 9,271 ✭✭✭✭✭
    Yes @Spyderweb , wasn’t an issue.

    Not to much water in the bilge when the opening is full of weed!!  :D

    I thought I posted this on my thread but it was @YYZRC ‘s . So I’m posting it here also.

    Started up my generator for the first time this season the other day. Started with no issues. But when I went to put a load on it it shut down and I got the UU code. I played around with it for a while and kept getting the same UU code and the LOC code every once in a while. I went to check the fuses but of course my meter was dead. I convinced myself that it was the same issue I had a couple years ago and ordered an injector and a water sensor. Went home, changed the batteries in the meter and ordered the parts. I ordered them from Parts for Techs and they showed up the next day! Went down to the boat , first thing I did was bleed the old injector to see how the fuel was, it was clean. Now since I had a good meter to use I checked the fuses. Sure enough, the F6 15 amp fuse was blown. I replaced it and she’s now running great! Now I have a new spare injector and water switch !😂

    Moral of the story, keep fresh batteries in your meter!!

    One of the rubber standoffs broke on my coolant reservoir, figured I’d post the part number if anyone needs in the future.

    What did you do to break that part?
  • aero3113aero3113 Member Posts: 9,271 ✭✭✭✭✭
    LoL, no! The rubber must’ve decided to give up.

    I started the generator today for the first time this season. Started right up ran for about 45 seconds then got a LOC message. Started it again and got a UU code. With all the trouble shooting I did a couple seasons ago I wasn’t wasting my time. I went right to the fuel injector. Took the cap off the Schrader valve and bled it with a pick into a rag. Started right up after that with no issues, I ran it for about a half hour with various loads. If you’re pulling you hair out either replace or bleed the fuel injector.

    Mine is a mess I'm sure. I've barely run it since we bought it. After getting it running , everything changed and it has sat....

    Mine was giving me **** last season. I could run the ac but nothing else or vice versa. Hopefully this season it isn’t an issue. I’ll know more after I splash and replace the plugs and oil as normal maintenance.

    I believe I have the oil leak on mine fixed.  I had to remove the flywheel and change a seal around the shaft.  This last weekend though, it seemed like my larger AC unit was kicking off once in a while.  The smaller AC seemed to run ok on it.  I may need to do some adjustments on the genny (I had changed voltage slightly on it a couple years ago).  Maybe my new AC unit is a bit more picky about that.  I plan to anchor out for 4 days this weekend, so we will see about the oil leak (although it will be cooler, so maybe no AC needed - not that I run it much on hot days either).

    I have a 7.3 ECD and its not been happy for a few years really. It starts fine but always sounds like its got a fouled plug even though the plugs are new and gapped correctly. I did a new fuel injector yesterday, bled the air out  and everything else seems to be fine with the exception of the fuel pressure. I am almost certain the high pressure fuel pump is on its way south.
    You can see in this video it never really settles at 45 PSI as it should. Its starts at 45ish and then is in the hunt with or without a load on it. Gonna order a new fuel unit today and hopefully that fixes the issue. The low pressure pump and high pressure pump unit have been replaced but that was  done by the previous owner and I don't know how long ago. Does anyone else have any insight?

    Update it was a bad out of the Kohler box spark plug. Never fired once. I change them every season.
