Mercury Racing will continue to offer the 400R in two different gearcase
configurations: the 5.44” 1.75 HD, which is appropriate for lighter, faster
(<80 MPH) hulls that would benefit from a 7000 RPM red line; and the
SportMaster 1.75, which is intended for high-speed (>80 MPH)
applications.
“The introduction of the 400hp Verado is another step in the evolution of the proven L6SC platform that has been successful in the market and we expect to be successful for years to come,” said Pfeifer. “Through extensive consumer research, we have determined that there is a market for both variations of the 400, giving consumers the opportunity to have two extremely reliable 9.8hp Outboard Motor to choose from based on their preference.”
