Six years after introducing its IPS engine-drive package, Volvo Penta announced that it had shipped its 4,000th unit this summer. The engine manufacturer says its IPS package has replaced shaft-and-strut propulsion on thousands of boats, making them more maneuverable, fuel efficient, quieter, cleaner, and easier to drive. “Volvo Penta IPS fundamentally changed the marine marketplace,” said Clint Moore, CEO of Volvo Penta of the Americas. “For the first time in my experience, consumers start the boat-show buying experience at our booth, asking us which boat brands are available with Volvo Penta IPS. [IPS] owners report significantly higher overall satisfaction than owners of cruisers with traditional inboard propulsion.” The 4,000th IPS unit was installed in a Cruisers 48 Cantius.
