May if you plan on throwing the tools away and restocking the case. I don't know of this particular brand, and the price might lead you to believe it's not total junk, but you're often better off with a good crescent, channel lock pliers and a hammer than crap Taiwan wrenches(AKA knuckle busters). I would say at least get lady kenmore or Lowe's Kobalts.

I don't know about your Cobra, but I would also make sure your kit includes Allen wrenches.

Good question though. I have a set of wrenches, sockets, crescent, channel lock screw drivers and vice vice grips in a battery box that I always make sure is in my boat before I launch. Also it has half a dozen wires with alligator clips on each end to jump across corroded out fuzzes. That saved my ass once in the ship channel!
