    I also checked the thermostat (and tested it putting it in hot water) and the cap and rotor which all looked great.

    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    The follow up question I have is, if the water pressure is that low-no code is being thrown-could my circulating water pump be the issue? and it not throwing a code?

    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    I also thought the water pressure was low especially with a load. Here's my concern though, clearly the water pressure sender is working as its providing a reading. I checked the impeller and even though its "formed" (which I have a new one and can change), if the pressure was too low or even...

    Is that what the correct water pressure should be? I checked the impeller the other day and it was perfectly fine.

    I used the info provided to get other readings from the vessel view. I have posted them below. To be honest, I have not researched what normal readings should be, but any input you have please let me know. The last screen shot is right before the boat when into guardian mode.

    So I do have a trim sender and trim limit on my sterndrive. The gauge is not working, would this cause me to go into guardian mode?

    Wait, I can do that? I read the vessel view manual and what your saying was not in there.

    But to go into guardian mode? I’ve had trouble with it once in the past, but didn’t go into guardian mode.

    One other question, which I dont think will cause it to do what it is doing is, I changed the IAC valve, and removed the muffler from within the throttle body (little white piece of sponge, which was black as the ace of spades) and never replaced it.

    Chris much appreciated with the video. I also thank everyone else who assisted. Just wanted to provide an update. I spoke with my mechanic and decided to change the impeller, but it was in perfect condition and was not the issue. I also used half of a 55 gallon plastic drum to submerge the...

    Both, In gear or in neutral (tried it both ways), when I get to the 2000 rpm mark, the engine alarm beeps and goes into guardian mode.

    I did. My newest issue is finding the serial number for the engine cause it did not recognize it and adding it to vesselview.

    Last sensor I can check is the oil pressure sender for the ECM. I bought one but it was the wrong size.

    Hey Chris, I think I definitely did that wrong and will be trying it again tomorrow morning. I would love your insight on how to correctly do it so I know I am doing it right. The one plug as stated before when I disconnected it, the engine wouldnt turn over and start and when I did pull it...

    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    I think I'm biting the bullet and bringing it to my buddy to have him scan it tomorrow morning. Aggravating knowing this is still happening and not having a code provided to my vesselview.
