    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    By saying the DTC was pretty much the same I mean the DTC was a 441 or 442 and the only data that was different from the prior tests was the engine coolant was 140F vs 86F in prev tests. I had the data on Diacom and brought my laptop home to figure a way to save the DTC in such a way that I...

    Well the coolant is in now. Was filled to the full mark after a few minutes of running. Owners manual does not mention any need to bleed any air. But there certainly could still be air. Unsure

    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    So had the boat put in the water today. Added another 1.5 gallons for a total of 2.5 gallons. (It's possible the jugs of VP VCS coolant are 5L rather than a gallon). Started engine, level went down a bit. Added a little more coolant. Did that twice. Third time the the coolant level did not...

    Motor 8.1 OSI anodos

    Is this closed cooling. If so there is one in the heat exchanger. If raw water cooled there is one in each exhaust manifold. And of course at least one on the outdrive.

    In the parts diagram it looks like it seals with a O-ring meaning it's almost certainly not NPT. Maybe get a new O-ring and re-do the connection.

    What do you think is wrong with the leaking hose connection? Hose damaged? Clamp damaged. Past the threads? The question is will I be able to unscrew the fitting from the exhaust elbow or might it snap.

    Not much gas in the tank? Gas tank pickup clogged. Antisiphon valve on gas tank. Clogged fuel filter. Does not sound like a spun hub. Fuel pump failing. Run off a test tank.

    New 5.7 overheating

    You put in a new engine with an old exhaust manifold? Closed cooling or RWC? I assume RWC. Replace both manifolds. If you put any gasket sealer on manifold to riser gasket, less is better.

    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    So looking at parts diagram for a VP V8 300 C-A. Ref # 54161974 is not for my engine. Ref # 54161345 looks correct for my engine. Shows a thermostat on the heat exchanger (#2) that is part of the closed cooling system (coolant). Ref # 54161973 is not for my engine. Ref # 54161344 looks correct...

    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    I had a Cruisers Inc 1987 24' boat with a Mercruiser 268?? (5.7L) engine and an Alpha One outdrive. With carb. Gave it to Boat Angel. I think they sold it for $87. (Yes less than $100). Everything was simple. But still needed work.

    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    Went to the boat this morning. The overflow had about 1/2" of coolant in the overflow. Started to add a gallon of coolant and it took the whole gallon and when finished adding the gallon the overflow was maybe 1". Still not where it needs to be. The The coolant was obviously flowing into the...

    2012 VP 300 C-A Exhaust manifolds getting too hot - DTC 441 & 442

    The boat is at a marina on a rack, so it's not like I can do testing every afternoon. The manifolds each look to have two identical looking sensors, one in the exhaust manifold towards the front of engine and one in exhaust elbow (riser) towards the rear. I was thinking of pulling the...
