The motor will overheat on throttle, low throttle or idle it will keep perfect temp.
New impeller, the sea water pump spin's the way it should (removed the square nut on top for inspection) New thermostat.
And no leaking found in cooling system using smoke machine.
I have the lower unit off at the moment and run a water hose directly into water intake.
Here is what I have noticed.
On initial start up the water flows fine out the lower bellow, after it starts to warm up the water starts to come out of the lower prtion of the transom.
Do you guys think there might be blockage somewhere backing up the flow and setting off the seawater pump alarm?
Does anyone know how to backflush this type of motor?
This is my first boat but I think I'm fairly mechanically inclined.
*note when I changed the thermostat i did find some small gravel debris I removed the 4 hoses on the thermostat housing they seemed clean.
*Also where does the impeller debris end up when they start to come apart?
Thanks!
