Update.
The relay was not the issue.

I removed the exciter wire and the water pump shuts off with the ignition.

I tested voltage on the output to the ammeter. I maxed at rpms and read 17volts at the highest and around 13 just after idle. My boat didn't come with a tach.

There is no noticeable difference from starting to not starting with the exciter wire detached.

I also sanded the name plate and found Mr12n451d type b.

I did just test the exciter wire its the only one with a square connector and a coil in the wire, the voltage increased in this wire as well.
