Anybody who has done much reading on this forum knows about the raging debate about which is better- outdrives vs inboards. At risk of starting a new fight, I will summarize what I believe is the consensus: Smaller boats or boats that will be stored out of the water tend to do better with outdrives, and larger boats stored in the water do better with inboards. The major reason I see in the arguments for the inboards being their simplicity and lower maintence and the fact that outdrives stored in the water have corrosion issues.
Now we have an explosion of new drive systems by various names, all of which turn out to be basically outdrives mounted differently that can rotate independantly ( and computer controlled). And they are mounted on the bigger boats that will rarely if ever come out of the water. Did they somehow overcome the downside of outdrives permanently kept underwater?
I'm not knocking these new systems as they do allow large boats much better handling and economy, but if the problems inherent with outdrives have not been solved, will we soon start to see a whole new wave of problems and failures associated with these.
 
I believe the IPS drives are nibril so no problems - the zeus may be aluminum - I know people are having a hard time getting the zincs and they are $$$$
 
I've had outdrives in fresh water for years and no corrosion. I'm either lucky or perhaps i just make sure my Mercathode system and anodes are all OK.
