Good morning all,
As some of may recognize this post, I have some updated information to share....it's not a faulty water pressure sensor, a pump, or anything to do with water pressure.
I decided it was time to bring in a pro with the proper tools to diagnose the problem, which at the time I thought it was a faulty switch relay ect. not so...Code 25 turns out to be code 325 or 326 depending on which manifold is overheating...oh...I just gave it away...If I can attach the image that I was sent by the tech, it will be attached to this post.
The rpm's that it goes into limp mode is still the same,3200 and up the starboard manifold heats up enough to set the alarm. anything below that, no worries.
So now we're on the hunt for the culprit. Manifolds and all associated sensors were replaced last year. The poppet valve was next on the list. He removed and cleaned the valve and the surrounding area as there was some crud in the housing. Didn't solve the issue.
This should be the screenshot of the scan. If not, here are the temps scanned on each manifold.
Port=125.44
Stbd.=214.44
Cheers,

Google it, there will be plenty of info with pics. Basically a blockage in the water pickup line that goes thru the transom assembly.
 
Googled it.. Thanks.
It was mentioned that this issue is usually associated with Bravos that are in the water full time.
The boat is on a cradle and flushed after every use.

Larry

My 300 dancer was kept on a lift and flushed after every use. Bravoitis cost me a motor. It is a definite possibility.
 
Hello all,
Well I've finally come to the end of the long saga of code 25.
I'll keep it short and sweet...exhaust shutter valve in the exhaust y.
The starboard one was clogged and not letting the proper amount of water flow.
Anyway...happy it's over.
I also want to thank all who responded to this problem with their thoughts.
