Ingemar Johansson, the Swedish heavyweight boxing champion made an appearance to pose with Wynne. Carl Kiekhaefer was stunned to see the huge crowds in the Volvo booth and was miffed at dealers asking him about the merits of the new drive. He was steaming over the drive because he considered the concept without merit and because Jim Wynne was involved. He never recalled talking to Charlie Strang about the AVC drive years earlier. Extremely noisy, even though compartmented with sound-absorbing material as liner.
Noise is combination of intake and mechanical.
Gear whine noticeable at part throttle although not at high speed. Steering extremely dangerous. Spun out boat at first hard left turn. Installation costs must run considerably higher than an outboard since one large hole must be cut into the transom to take the engine mount. The Volvo outboard-inboard drive, aside from its cost and weight disadvantages, has all the other disadvantages of an inboard installation and while a certain segment of the public might go for it, I do not believe it is a threat to outboard motors at this time.
