    new engine overheats

    well I thought I'd stop in and say I found the issue. ,,,,,,,when I bought new manifolds they gave me the wrong manifold gasket set. it wasn't allowing enough water to flow out of the motor. pretty basic but what a pia tryna find the issue thinking it was rebuilt correctly before it was put...

    Accumulated parts I'd like to part with.

    Like many of you I'm sure,, I have accumulated a bunch of parts I dont need and listing and selling in these forums isn't allowed. is there a site y'all might recommend to list them for sale. not ebay or Craig's list, maybe an actual boat site.

    new engine overheats

    I do feel its bypassing too much since the temps vary so much. I have nothing "bravo" tho. I will check into that right now,, thank you. I thought they were the same part # between the 5.0 and 5.7.

    new engine overheats

    I can lean on the risers with all my weight and stay there and not get too hot. I was just reading 165-170* + - 4* on both risers even at 195-200 on the temp gauge. they actually get hotter after sitting a while waiting to cool down. the engine read 195*+ so that is getting warmer than the...

    new engine overheats

    The biggest issue here is, I did the engine swap 9 almost ten years ago. I ttttttthink I put all that back together correctly but time has me questioning everything. we heard a strange noise on the water as I shut the motor off,, it sounded like something spinning fast then coming to a stop...

    new engine overheats

    The hose configuration is what's driving me nuts...... both elbows are teed together and run under the motor to a junction , the thermostat also , everything ties together for the drain system. I don't have decent pics of the junction, its busy under there.

    new engine overheats

    I believe the gauge is correct. after start up and wam up it rises to just shy of half way between 160 -180 and sits there till it creeps. every time from a cold start it sit right there. ? today it ran perfect n the hose again, right there. then in the water it did the same, started...

    new engine overheats

    sorry I read that wrong. it got over heat hot on the hose before changing the stat. and ithen t ran cool for at least 15 min at idle putting around near the ramp. even under way slowly. it didn't rise til after a few minutes at about 3200 rpm then once hot it didn't want to cool.

    new engine overheats

    it over heated on the hose before replacing the t stat. and in a poor test the old stat dID open in a pan on the stove. although i didn't have a working thermometer and it didn't open til the water was almost at a boil so that didn't rreally tell me squat. another day flushing and testing and...

    new engine overheats

    I went ahead and opened up the T-stat housing and found the stat was the one I put in when I re powered in 16. it never was taken out or changed by anyone else after all.. I put a NEW stat in anyway it and I took it to a pond to test rather than wondering if the hose was feeding it enough...

    new engine overheats

    oK yes I understand the thermostat does control flow. I'm trying what I can to determine why its over heating.. Do you have any OTHer suggestions as to why it may be overheating? as I said water SEEMS to be circulating through the system yet it slowly gets hot. it takes about ten...
