Flip a switch and hear the roar, Lake Minnetonka

Friday, November 21st, 2008

With the flip of a switch, some motorboats get really, really loud. A special feature diverts the boat’s exhaust from underwater to an outlet in the hull. It’s supposed to give the engine more oomph, but there’s another attraction — your boat will bellow.

“Why does a guy own a Harley with straight pipes? It’s cool. It looks tough,” said Wayzata boat dealer Dan Gau, trying to explain the appeal, which he doesn’t share.

The exhaust diverter is marketed under names such as “Captain’s Call” and “Silent Choice.” But it can’t be sold or used in Minnesota. These devices have been against the law here since 1980.
