Work forwards. Chances are it is in the strainer or clog at the through-hull with something growing or getting sucked up in there. If you are sure the impeller was installed correctly with a new gasket
1. Check that the through-hull is not clogged.
If the seacock is operating correctly and in good shape, close the seacock and remove the hose. Open the seacock and if water is coming out, go to the next step. Put the hose back on and replace the hose clamps with two new ones. If water is not coming out, unclog the through-hull. You can sometimes blow it out from inside the boat.
If you have the grate strainer type through-hull, you need to dive the boat and clean it out from the outside.
2. Check the strainer. Close the seacock and unscrew the strainer bucket and remove it. Clean it out and put it back together.
3. Just to be sure, raise the hose from the output of the sea strainer and fill it with water and look at the pump for any leaks
. If no leaks
, install the hose back on with two new clamps.
If the engine was running hot before, then you may need to clean out the heat exchanger
. But again, no water, fresh impeller installed correctly, usually clog before the pump.
