ive got a 92 400 EC. Starboard motor has been overheating at 225. I'm hoping I've just got bad impeller or trash stuck in there restricting water flow. Does anyone have a diagram showing where impeller is and places to check for restricted water flow? This happened right after we went through weeds/debris. Port was overheating too but then magically stopped. I have the starboard seat off. Here's what I'm looking at.
