I think it’s okay. At first, having ASW and that gun line it sounds too cheap, but Nordmark has an extra hull point, synergy, and is more durable at 5. It’s probably a fair cost here too.
Comparing Repair vs. Reinforce Installation vs, Supply Run:
Repair: Once per game prior to movement, you can attempt to repair a local friendly ship. If so, neither unit can move or use gun attacks that turn. At turn end, on a die roll of 2 or more, remove 1 pt of hull damage
Reinforce Installation - Instead of attacking during your Surface Attack step, this unit can Reinforce Installation on a damaged Installation in an adjacent sector. If it does, roll a die. On a 4 or higher, remove 1 point of hull damage from the Installation at the end of the turn. An Installation may not remove more than 1 point of hull damage per turn. You may remove only 1 point of hull damage per game with this ability.
Supply Run: Instead of attacking during your Air Attack step, this unit can make a Supply Run in its sector. If it does, roll a die. On a 4 or higher, remove 1 hull point of damage from an Installation in this sector at the end of the turn.
Notes: - None of the repair abilities allow you to attacking (though it could be argued that you can use Smoke/Torps with Repair, but it repairs a ship on 2+). - Reinforce Installation allows the Installation to fire, but succeeds half the time... just like supply run. - Supply Run has no limit to the number of times it can be used in a game or turn. (Yes, I've used 3 of them in conjunction with a HSB... most I've healed in a turn was 2)
I could see an argument that the Monawi should be 4/5 points, so I think 5 points is the right call, especially with how Reinforce Installation is currently worded.

EVADE TORPEDOES: Once per game, when an enemy unit would make a Torpedo attack against this unit, you may roll a die. On a 3 or higher, the Torpedo attack automatically misses instead. This unit can't move during the Sea Movement phase the turn after it uses this ability.
LIMITED ASW THREAT: This unit doesn't penalize Torpedo attacks of enemy Submarines in adjacent sectors.
Reinforce Installation - Instead of attacking during your Surface Attack step, this unit can Reinforce Installation on a damaged Installation in an adjacent sector. If it does, roll a die. On a 4 or higher, remove 1 point of hull damage from the Installation at the end of the turn. An Installation may not remove more than 1 point of hull damage per turn. You may remove only 1 point of hull damage per game with this ability.
