Marine Engines

What Makes a Good Engine Room?

While your boat may not have a well-designed engine room, there are modifications you can do to make it safer and simplify your maintenance chores.

Marine Engine Horsepower Ratings

Understanding what horsepower is, what it gets you, and why less is sometimes more can help your engines last longer. Learn more about horsepower ratings mean here.

Clean Marine Engines from John Deere

John Deere’s new 4.5-liter marine diesel meets EPA Marine Tier 3 requirements and has enough power to replace the company’s older 6.8-liter Tier 2 engine.

The New Magically Maneuverable Outboard

Old salts will roll their eyes at the Miami International Boat Show this year when Mercury Marine and Yamaha debut new outboard control systems with joystick steering that makes it infinitely easier to look like a pro in even the most challenging docking situations. But as with power steering and digital controls, the salts will learn to love the joystick.

The Great Propeller Fight

I recently contended with a few of my colleagues here at Power & Motoryacht that most of the propellers we deal with in boat-test reports are of the fixed-pitch variety and therefore, to mention fixed pitch as a qualifier in a list of specifications constitutes an exercise in basest redundancy.
