    Merc 5.0 TKS Heat Issue

    The alarm circut is triggered of a temp switch on the thermostat housing tan blue wire going to it. Its in parallel to oil pressure switch and drive lube sensor. Any of those three sensors go to ground to trip the alarm. Easy to test one by one. Unplug them when alarm goes off. Verify temp...

    Question on fuel

    I suspect if you had to do multiple or frequent carb rebuilds there was contamination of the fuel tank that continued to dose problems into the carb or the carb cleanings were not successful in completely cleaning the carb. Im not throwing you any shade, as Ive had plenty of issues rebuilding...

    4.3 Mercruiser cold start issues

    Pretty well known issue with hot rod folks here. My coworker has a holley on his 69 firebird, doesnt even try to start it in the spring without replacing the float bowl gaskets because of leaks. The one piece fuel bowl and no power valve blow out issues are two real advantages of the Edelebrock

    1989 5.7 Mercuiser exhaust plugged

    Freshwater they generally dont corrode, but could have debris in them. Would open to inspect the water passages. Also possible that if the water pump impeller disintegrated there are pieces of it clogging water flow, especially in thermostat housing . folks here can walk you through it.

    4.3 Mercruiser cold start issues

    In general the edlebrock is a good carb very easy to tune If needed. I have. Two one on the boat and one on my 65 GTO. I wouldn’t hesitate to by an other one.

    1989 5.7 Mercuiser exhaust plugged

    Remove the risers from the manifolds and inspect the water passages. not sure the year but if used in salt or brackish and they are 5 + years old likely they will need replacement . Drain the manifold before you take the riser off

    2014 350 mag cat, port manifold/riser considerably hotter?

    Its typical to see a 20-30 degree difference in manifold temps. If you can keep your hand on them I suspect you are fine. Might want to use an IR thermometer to check temps.

    Question on fuel

    It depends on how fast you consume the gas. In my experince if you burn through it I have not had issues from typical pump gas. I run ethanol from the pump in my jetski because I fill it from a 5 gal can and go the marina to fill the boats 37 gallon tank because it is easier and worth the $ for...

    4.3 Mercruiser cold start issues

    Maybe 25-30 seconds. It seems like a long time when cranking and the buzzer is going off. I think not only is it refilling the bowl but getting gas through the idle circut passages again.

    Boat will run the same if it has holes here, brazed, or epoxied. As long as the rest of the bell housing is not corroded you are fine

    Back again

    Depends on what you want to do with the boat. Price and warranty are nice. For 20 years my family (parents bought used and i took it over) had a Sea Ray 170/3.0 engine - boat was great for many reasons but in the end was small as my kids got older, pounded in rougher water., but was very...

    4.3 Mercruiser cold start issues

    It does not bother me so much because otherwise the boat performs really well. my dad lives on a lake so i keep the boat there, he is retired so maybe with too much time on his hands bothers him more. He sprays a little staring fluid in the flame arrestor this runs the engine until the carb...

    5.7 mercruiser heads question.

    1996 and up vortec heads will be the same and intakes will swap over. If you are swapping an automotive engine not only the freeze plugs but head gaskets and water pump need to-be marine. If yku are using a truck engine the cam will work for marine applications, but car engines have different...
