Great running AQ230B Marine engine that was not rebuilt as it didn't need to be. The screen strainer in exchange should probably be replaced with your old one as bottom of it seems like would possibly allow smaller things to get into. The whole cooling system has been flushed out and is free of any sand or impeller parts.
Has new plugs, points, rotor, impeller, impeller rear seal, and 4 copper cooling tube seals. I now have a video on YouTube showing this running and it is titled Volvo Penta AQ230B red cover engine.
This is the perfect replacement engine for all Volvo 4 cylinders pre SC.
