Just bought a 2003 SR230. One of the engines cranks right up. The other won't. It does turn over. I have hooked up the YDS software / cable found at the rear of the starboard side of the boat and can read the starboard engine just fine. Bump the starter on the port engine - nothing registers on my computer in the YDS. Is there a separate diagnostic plug for each engine, or just the one plug and you use it for both engines individually bumping them? I've looked in the port side compartment but don't see such a plug. Short of removing the port side ECU and sending it off for testing, is there any other way of identifying whether or not it's the ECU? Thanks in advance.
 
As far a I know, one per engine. The ports should be located close to each other. You have two ECUs, right?
 
I do indeed have two engines each with its own ECU. I will have to look deeper in the area of the one connector I did find in the rear compartment of the starboard side and see if I find another connector for the port-side engine. I have not run across a single post, anywhere on the internet, that identifies this situation. I guess it's just a fluke that the one connector I did find was for the starboard engine that does run. Thank you for your response. Anybody else care to weigh in on this?
 
I have same boat, there are two connectors back there, one for each engine, mine takes a couple of engine cranks and restarting software for it to read the engine sometimes
 
Awesome! I thank you so much. I will dig around some more tomorrow. Not new to boating, but I am totally new to the jet boat platform.
