2010 Challenger 210 engine turnover but won't start

[twgalow]

I have 2010 SEA-DOO 210 CHALLENGER SE. Was out on the lake the other day and sucked up a bunch of weeds. Didn't realize it until I got an alarm beep for exhaust overheating in port-side engine. I immediately killed both and let things cool for a bit. I pulled as much as I could from under the boat and used the second engine, which had some stuff in it but hadn't overheated, to navigate slowly off the lake. I cleared all the junk out of both impellers, but the engine that set off the alarm turns over but won't start. The other engine seems fine and starts normally. Any suggestions about where to start or what might be wrong here is MUCH appreciated. Thanks.
