1992 BlackMax 150 HP. This black tar stuff that is sandwhiched between this module oozed out while boat wa just sitting in the driveway. Temperature outside has been 95 - 100 degrees. Is it possible that it just got very hot under the cowling and caused this? Should I worry? Motor still seems to run just fine, although I have only run it with the earmuffs on in the driveway. I hope the picture comes out correctly. Thanks in advance for all any replies and opinions.

What year / hp is that merc.?
It could be from the outside heat.
BUT, remember that the temps while running are up around 143*.
Pack could be getting hot from a bad ground connection (green stuff on the black wire), too much ac current from the stator etc...
Or the epoxy potting on the switchbox is just breaking down, i would change it for piece of mind, and check the specs of all of the electrical components. keep the old one for a spare.

Supposedly a 1992 Merc. 150 HP Black Max. I left the battery selector switch on for 10 days. The key was off but I wonder if a small current of some sort was running through that box (what is that box, anyway? I don't have a manual). California heat is brutal in the summer. Boat is always in my garage. This is the first time in 6 years that I left it outside for more than two days and it was HOT outside.

Black Max Wax? Looks to be overheated, whatever it is..

The insulation on that black wire looks like it may be a little melted as well unless that is that black stuff that oozed onto it. I would maybe consider replacing or repairing the wire also when you go to replace the power pack if it is melted that is.

I agree, the potting is melting out of it, I Would replace, the switch box( Power Pack)
