When the impeller is broken it stops the supply of water to the engine and results in overheating. It causes the electrical components inside to get corroded. This corrosion may result in the outboard not starting.

The fuel injection system can be replaced. The warranty of Honda should cover the replacement. The corroded parts can be replaced or serviced from a servicing center of Honda.

Start with the easy solution I had the problem once and went through and changed the pump thermostat after I did this the problem was still there. Turns out where the tubing fit onto the plastic spitter fitting was clogged. Cleared the tubing and the spitter and was good to go.
