The motor runs fine just over

The motor runs fine just over heats like boiling the water. Replaced thermost flush system still over heats getting water but on stern side the hose will leak because its hot. Ive read other post looking for the right anz thanks.
 
Have you replaced the OD impel

Have you replaced the OD impeller lately? Did you clean the heat exchanger w/a rod/brush and flush it out? Test or replace the coolant pressure cap? Overheating any engine is not a good thing especially one w/an aluminum block.
