Also, keep in mind that their are two seperate types of diesel engine malfunctions. The first type acts on a specific value.
Example:
Ahead Flank = 11 kts
or
Ahead Flank = 0 kts (and a few in between)
There are also some that deal with various percentages.
Ahead Flank = 75% (of what that speed for that particular boat called for)
There are also combination files plus a whole lot more to mess up your day
Happy Sailing
