    2004 merc 350 mag mpi high temps on new dry joint manifolds, one thing after another with this boat

    Hi, may I ask why. As far as i understand water is pushed up from the joint's second tube which is sort of directly linked to the impeller outflow. Or am i wrong? Thank you for your thoughts

    Hi stang32, thank you for your reply! yes, this is without -t-stat... just like in good parts of the US, Winter is back in Austria too, so testing it on the lake is not an option right now. What I have found out though: new / replacement risers have a water-flow-connection between the front and...

    Hi, thank you! I do normally use muffs esp. when flushing the system with antifreeze. how ever, i wanted to check on the capacity of the impeller/for a proper outflow, as you mentioned, the muffs will only suffice for idling, but not much more, that´s why i tested it this way.

    Correction... Few gases and no water

    Ok, so this may be a beginners question: should there be exhaust gases/ water coming out of the propeller on my bravo III... because there are neither water nor exhaust fumes coming out... I cannot remember if there ever was, since i am also servicing our life-guard boat with a Honda BF135....so...

    2004 merc 350 mag mpi high temps on new dry joint manifolds, one thing after another with this boat

    So I have disassembled the whole water system, i could not find any obstructions, water flow seems to be ok in risers and elbows and everywhere else too. after reassembly i built a "tank" to test the water yet again and especially test the impeller. i checked water flow and it seems to be...

    2004 merc 350 mag mpi high temps on new dry joint manifolds, one thing after another with this boat

    mh,at some point i was thinking about hunting a ghost too...but i had a cracked manifold as a likely consequence of the heat problem (actually it cracked twice ...see below), in different forums I read of temps below boiling temperature on the manifolds, risers, elbows, mercury itself has no...

    thank you for your thoughts, the gaskets are/were installed according to the manual , eventhough i sometime wonder why that front piece has to be restricted that much. i´ll inspect those t-fittings more closely tomorrow (even though one of them is new), i´ll also change the impeller (eventhough...

    please excuse my ESL-skills of course it is not stern but PORT (-sided) one being brand new

    2004 merc 350 mag mpi high temps on new dry joint manifolds, one thing after another with this boat

    what bogs me, is the fact that the elbows are perfectly cool, but the manifolds/risers are too hot ...gaskets could be a reason, and i have suspected this too, how ever, they seem to be in right order (restriction btw riser and elbow + "looking" into the direction of travel)... so since the...

    there are two gaskets manifold- gasket- riser- gasket with restricted flow- elbow they seem to be the right gaskets and also correctly installed

    raw water cooled... the water temp shown on the gauge is exactly where it is supposed to be, the IR thermometer (actually two diff. makes, just to make sure) show water temps in hoses/pipes/ engine(as far as one can tell) just according to the specs, oil temp (measured at the filter) is ok too...

    2004 merc 350 mag mpi high temps on new dry joint manifolds, one thing after another with this boat

    though with me temps are as follows: manifolds (both sides) 200-250°F (cruising over 3000rpms) and riser (both sides) can go to over 400°F (!!!!!!) ...but then the knee is cold (by cold i mean as cold as the lakewater) The boat has been in a professional garage (licensed mercury dealer) with...
