Hi guys,

3 years ago I bought my boat with a 1996 200 Ocean pro on the back and it has run flawlessly since purchase.
I was able to put in for the first time over the weekend and I was getting a check engine light at idle and low rpms.
All the fuel line, check valve, primer and water separator filter were replaced in the summer of 2022.
I was able to run at 3000 - 5000 rpms with no issue but as soon as I came off plane, the alarm would sound.

Just looking for some expert guidance on places to start looking.

Thanks in advance.

Nate.
