This will eventually makes sense & “cent” if you keep the boat &  as time goes by…………You own a boat with a very sophisticated engines. In fact, your engine is one that is used as a standard to what many are gauged by.. In so many words, you have a really great engine, but one with nothing to “see” what it is doing.. .The builder/installer of the vessel  “cheaped out” so to say,  and installed it so you are “Driving Blind”……..Unless you are willing to upgrade your engine monitoring system, I am afraid that you will never to be happy and issues like this will happening as long as you own it..

Hiring someone from Cummins or an independent mechanic will be $$ ill  spend as your base issue will not be solved.. You need a “PROPER” engine vital sign monitoring system———— That is “Plain & Simple”..
