Ok I am looking for some help here! I will start by giving a quick history. I purchased a used DT25 (Suzuki 2 stroke) and was having cooling issues. First thing I did was change the impeller, wear plate and water pump gasket. I also changed the head cover gasket and high temp alarm. My problem is I am still not getting any cooling water up through the engine. I made an adapter to hook up the garden hose to the cooling tube right where the water pump grommet connects and I can run the engine with no problems both the pee hole and water exhaust ports are clear and the thermostat is functioning properly. So I know the problem is in the lower unit. I was able to hang the lower unit in a barrel and spin the drive shaft with a drill motor, first time I did this I got no water thru the water pump. I removed the impeller and applied a layer of grease inside the impeller housing and retested. I was able to get water to flow that time but not enough to move water thru the engine. Please any suggestions? I want to buy a new housing but I also do not want to continue to throw wasted money at this.
