Need more info. You have twins yet this only happens with one or both motors?
What do you mean "not easy to reset"?

Don't see a breaker resting by itself. There are thermal breakers but don't know of them being used on a Merc.

The part number listed is the 90 amp fuse, if it blows it needs to be replaced. If it blows the most probable cause is the alternator.

What is the flush system?
