Easy if the boat is on land but in the water try to have an exit hose flush into a bucket/strainer. The first so you can dislodge a piece that is stuck in the usual direction of the flow and the latter to make sure that you know what did come out.
I've had this with my engines (with sterndrives) and you just keep worrying if you flush, solve the issue but are not sure you got it all out. In fact, the problem reoccurred some time later after a piece that was moved by the flushing relocated itself. Luckily it came out right at the first hose I disconnected but it was not a good experience.
It's a big design failure that a desintegrating impeller can move upflow in big enough pieces to block a heat exchanger.
