Volvo IPS dwarfs them in sales though. One issue is using Cummins and not offering larger engines.
Really? You need more than 715hp - which is what Cummins mated to the Zeus drives. And, they are in tunnels
Seals are the BIGGIE and striking logs and containers does more damage. But it's worse on the conventional shaft drives that aren't protected with nozzles and flanking rudders.

ZF Marine does the Zeuz drives now. No shortage of parts.

I would take the Cummins just for the engines alone. Only good thing about Volvo is they make lotsa $$$$ if you're a mechanic for them
