Cylinder 5 misfire-

SPN 65595 CM0

Mech system not responding properly-

FMI 7 oc 4

so I also noticed that it says these codes even if I unplug batteries for a minute and hook them back up, it will read this code without  the motor even running, just turning key forward. Is there a way to reset the codes and see if it comes up again?

Has anyone else had a problem with their screen not loading and just flickering on their 2020+ plus malibus? My boat screen froze while I was out, and now it won’t fully load it just shuts off and flickers. Any help is appreciated 

Hi, just purchased a 2004 boat had water leaking from the drain bolt in lower block on left side.

Last owner definitely had issues with it as it was gasket sealed up only started leaking when engine got up to temperature.

I removed Brass bolt, treads are stripped from the blot, also purchased new brass replacements unfortunately it won’t go in the tread in block itself looks eroded and not much tread to be seen. Any tips on direction to go?? 

What specific fault codes are there?  Usually an SPN :FNI format (SPN91:FMI4 for example).  

Indmar Monsoon has 2 bad fuel injectors.

These aren't sold anymore and I found 2 possible suggestions.

AC Delco 19244617

Or this package
