After doing some troubleshooting on a friends boat, we have determined that the computer needs to be repaired or replaced, and have not gotten anywhere in finding a solution.
The problem is that the relay associated with the fuel pumps (second one in the circuit) is not energizing for the brief period after turning the key on, like it is supposed to. It seems like the input to the computer is supposed to create a briefly held ground path for the relay to be turned on, but isn't. I have verified this operation on my boat with the same engine, and after installing my boats computer in his boat, his runs great.
Long story short, I have not researched this a lot yet, but he has called everyone from a Correct Craft dealer, PCM, Discount Inboard Marine, and a couple ECM repair places he found on the internet and hasn't gotten anywhere.
The story he is being told is that they do not make these any longer, and has not found anyone who can help him out or point him to a solution.
Because there are a lot of these boats still in service and running strong, I have to believe someone has a solution for this, and thank you in advance for your feedback.
Have a great day!
