    I just got the motor and put my hand in the stream at idle and its pretty hot
    I can only hold my hand in it for 5 or so sec before I have to pull it out.
    I have a 25 4stroke and it dosnt get that hot at all
    I thought maybe the Tstat was stuck so I pulled it out and the temp dropped to what I thought was normal ,i didn't drive it just idled without Tstat

    Also  the water pump was just changed and it isnt flowing much water out but watching some YouTube vids they seem to all trickle out 

    Is this normal ?
    Thanks

    Put the Tsat back in, the water coming from the tell tale on the engine will be hot, as it passes through the head. It will not have much pressure until the engine comes above idle.

    But it should still be pissing at idle.

    I believe the tstat allows the impeller to build pressure - causing a stream not a trickle.

    Put the tstat back in.

    the water coming out of those will be hot, it's normal.
