In terms of sweeping changes to a marine engine program, they don’t get any bigger than Mercury Marine’s move to a 4.6-liter V-8 platform for much of its outboard line. Check out the article, below, about the introduction of the V-8s across outboard engine lines!
While there are six-cylinder outboards—most notably the Verado 350 and Mercury Racing Verado 400R for the high-performance marine market—still remaining in the Fond du Lac, Wis., company’s product portfolio, the future is decidedly V-8.
As for the direct-injection two-stroke OptiMax engine series, it has been discontinued. With the exception of one commercial-use model, Mercury Marine now is completely out of the two-stroke outboard engine market.
Members of the marine media learned about the changes—and experienced the new outboard products firsthand—during a recent clandestine event at Lake X, Mercury Marine’s recently reopened private testing and product development facility near Orlando, Fla.
All based on the same 4.6-liter V-8 platform, the new outboards include the Mercury Racing 250R and 300R, which are both naturally aspirated as opposed to their remaining supercharged Verado 400R and (Mercury Marine) Verado 350 siblings.
