If you see them, note time and description of the ski and people. Send it to me. I have been reading about the 2 stroke engine used in them emitting more than 30 percent of fuel into the water and air. More
"The carbureted two-stroke engine, until very recently the standard powerplant of the PWC industry, together with outboard motors generates over a billion pounds of HC emissions each year. These high emissions are attributable to the two-stroke engine's emission of as much as 30% of its fuel charge -- part of which is oil -- into the water and air. The EPA claims that just 7 hours of use of these older carbureted marine engines releases as much pollutants as a modern car driven 100,000 miles."
