Agreed.. I still want to see how they plan to cool them. They must get extremely hot. My guess is they must attach them to the engines internal cooling system or through the raw water system. (another thing to flush or break

)
But it is a big step in the right direction. It pretty much eliminates carbon emissions. These HP engines will have less impact on the enviorment then that of a 15 horsepower 2 stroke outboard from the 1980's. Just shows how the powerboat industry gets in front of and works to make our lakes and waterways greener.
