    Water pump leak?

    Maybe it’s just this one but I looked in to the Johnsons and they’re $330. The junky Amazon one was $85. Obviously still not worth it but I was unable to fight the temptation! Aaaand now we’re here. I would say lesson learned but seems like I’ve learned this one before.

    Water pump leak?

    Still issues with the new RWP. I had it running on the hose hookup and the thermostat got up to about 185 and I shut it off. The IR thermometer didn’t really tell me a lot (probably cause I don’t know what to look for to diagnose). The hoses on top didn’t seem to be getting warm and didn’t feel...

    Water pump leak?

    Will do! Only got a week or 2 of season left in KC and the other pump won’t arrive for a week or 2 so gonna give it a go and see what happens. I have the thermometer and will update. Thanks!!

    Water pump leak?

    Question on this, if I didn’t have any impeller grease. Would regular marine grease work? I have an oem impeller that I can put in this thing, i thought the grease was lost but it’s still in the box. So more of a question for future reference.

    Water pump leak?

    Just to add some confirmation to that and maybe save someone else the time of trying to save a few bucks on Amazon here’s a picture of the NEW impeller that came in the Amazon pump that was delivered today. Came pre-broken, cracked on the base of one of the fins on top.

    Water pump leak?

    I ordered one on Amazon that arrives tomorrow 😬. Looking at the link you shared, I might regret saving that $115

    Water pump leak?

    Wondering also if the rust at the base of that stem may be an indicator that water is getting past that seal.

    Water pump leak?

    Thanks @ESGWheel ! Got into in and here are some pics. It all looks to be good with the impeller. There’s a chance that last time I only ran it for a 3-4 mins and this time was closer to 10 but I’m not 100% sure. Here are some pictures. I’m thinking if I reassemble and still leaks than I need to...

    Water pump leak?

    Found this video on YouTube Same motor. Looks like same issue. He walks through a few different repairs before landing on the solution for him. Impeller and O ring, hose sleeves that connect to the housing worn out, and then finally replacing the entire pump assembly because the built in seal...

    Water pump leak?

    4.3 GL-D 3869251 4012141889planning on taking the boat to the lake today but figured I’d be smart and start it at home first this time. Noticed a little water getting splashed around by the belt. I think it’s coming from the water pump? The other thing that seems odd is last time I ran the boat...

    Is this water hookup for winterizing or for running out of the water?

    Does running it using the feed affect water temp readings? When I finally got the boat running and let it idle for a while I noticed it didn’t move past 100 or so. Do you know if this is due to where the water is coming in? Thanks

    4.3 GL-D Electrical Issues

    This is the fluctuating I was referring to. I can hear a very slight change in the sound of the motor when it’s spiking but I’m not sure if that sound comes through on the video.

    4.3 GL-D Electrical Issues

    Yes it works but it’s a little jumpy. I was thinking of starting a new thread to figure that out. This is the sensor next to the distributor, right?

    4.3 GL-D Electrical Issues

    I just posted a reply to @alldodge about the ran/black wire. I think it goes to the oil pressure switch but I can’t find said switch.

    4.3 GL-D Electrical Issues

    I took a closer look at that wire and took a better picture. Based on the diagram you gave me, I think it goes to the oil pressure switch (which I cannot find). There’s another diagram I found that says it’s for a 4.3 gl (attached) but it doesn’t show the 2 Exhaust Overheat Sensors (which are on...

    4.3 GL-D Electrical Issues

    Well, changed the fuel filter and it runs fine! The filter that was on there was pretty loose so I wonder that was the main culprit.

    4.3 GL-D Electrical Issues

    Yep! 1st boat and don’t really have anyone experienced to show me the ropes. This site has been a tremendous resource. I’m definitely taking the advice I get from friends and running it through here to make sense of what’s what. Not working at the moment so hopefully when I am I can get some of...
