Electric Water Pump???

[Knightwarp]

Looking for marine engine mechanics. I have a question. I have a Mercury 35 and have changed the impeller, (the old one had no tabs left), and then found the powerhead at the exhaust manifold gasket bad, and still it doesn't pee. Is it possible to rig up a small 12 volt electric water pump and flow the water through the motor the opposite way? There is no thermostat so the water should flow freely then. I will remove the impeller to allow the water to come out without blockage? I am lost and willing to modify just to get cruising and fishing again. Thanks to anyone who can answer this.
