Yea I'm not so worried about maintenance I am worried about the storied water ingestion problems those systems are known for, also the vibration issues with jack shafts.
Also I have not heard anyone say anything good about I'O's outdrives on this or any site.
I know they are often very efficient power wise but that is all awash to me as they are also the only system I know that will sink your vessel at sea if a rubber bellows splits. There is a fellow that had to run his 25 footer into the sand to keep it from going completely under, it was a new boat, literally on its first full fishing trip and the bellows had some type of fault in it. It split. the two bilge pumps could not keep up with the ingress of the water and she just made it, got beached by the coast guard barracks. That was something to hear on the radio.
