I wouldn't both with a rebuild way to expensive for that engine. BUT i suspect you can find a good powerhead for next to nothing if you keep your eye open. Lots of Merc inline six still available - most have rotten electrical harnesses that do them in. You should look into how far back a powerhead swap is possible with your mid before throwing in the towel.
