BMW Making New 300-hp Diesel Outboard with OXE

Coast Guard Tests Diesel Outboards on Small Boats. Is a Diesel Outboard in Your Future?

In a move that could make your cruising life easier, the Coast Guard is testing diesel-powered outboards on some of its Fast Rescue Boats. If the tests are successful, and more diesel outboards move to the recreational boat market, it could mean that you wouldn’t have to carry separate gas on board for your RIB or dink if you have a diesel-powered cruising boat. It’s also possible that diesel outboards will become more popular as the primary engine(s) on larger recreational boats. The Coast Guard test involves 175-hp Mercury Optimax outboards, as well as 200- and 300-hp units, and will…
