Sometimes what you don't hear tells you as much as what you do hear. I'm not surprised there are a couple of cases of pods being destroyed or people having problems with pods, although do find it interesting they are Zeus and not Volvo. However, there have been a lot of pods sold at this point. They are no longer "new." They're established and successful. If there were major issues or the product didn't have some very nice attributes we would be hearing a barrage of complaints and pods would be on their way down and not up. Also, boat builders would not be risking their future with an unproven technology.
Pods are proven now and they have a space in the market. There are boats on which they're a great choice. Today, I wouldn't personally buy a boat just to say I got pods but I wouldn't not buy one because of them. I'd evaluate the entire boat and all it's features plus my intended use and location. Pods didn't revolutionize the industry like they might have tried to convince us would happen. But, largely due to Volvo, pods built a significant base in the pleasure boat business. I say due to Volvo as they're the ones who really promoted their IPS. Brunswick getting into pods for recreational boats was as much defensive as anything. They weren't going to use Volvo and they didn't want to lose sales because they couldn't match them. If Marquis was going to have pods, Sea Ray had to as well.
There's not an engine or drive out there that can't have problems, but from what I've heard or, more importantly not heard, pods have held their own quite well.
