Abstract
A pump for pumping cooling fluid to cool a marine drive comprises a pump housing defining a chamber and an impeller in the chamber. The impeller is rotatable about an axis, and the pump is configured to automatically adjust and maintain an axial compression force on the impeller so as to maintain a consistent seal between the impeller and the pump housing. In other examples, a marine drive comprises an inlet configured to receive cooling fluid and a pump configured to pump the cooling fluid to cool a component of the marine drive. The pump comprises a pump housing that defines a chamber and an impeller compressed in the chamber. The impeller is rotatable about an axis, and the pump is configured to automatically adjust and maintain an axial compression force on the impeller so as to maintain a consistent seal between the impeller and the pump housing.
