Diesel engines soon offered greater efficiency than the steam turbine, but for many years had an inferior power-to-space ratio. The advent of turbocharging however hastened their adoption, by permitting greater power densities. Diesel engines today are broadly classified according to Their operating cycle: two-stroke engine or four-stroke engine
In Europe diesel engines are more popular, ranging up to 400 hp in models such as the Volvo Penta D6A-400. Other brands of sterndrive include MerCruiser (produced by Brunswick Corporation's Mercury Marine, which also manufactures outboard motors). Mercruiser have a slightly larger market share in the US, while in Europe Volvo Penta has an ...
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle , making a rudder redundant. These give ships better maneuverability than a fixed propeller and rudder system.
Verado engines are available in 250 hp and 300 hp (V8), 350 hp and 400 hp (V10, introduced in 2022), and 600 hp (V12) as of early 2021. In 2007 Mercury Marine began selling its Zeus drive system. [6] Developed by Mercury and its joint venture company Cummins MerCruiser Diesel (CMD), the Zeus drive is a dual-engine pod drive system.
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution.

Maybe we all watched a little too much This Is Us and are still mourning the loss of Jack Pearson, or maybe a kitchen mishap as a child has left us wary of slow cookers. Whatever the case may be ...
The 44-foot motor lifeboat was the standard workhorse of the United States Coast Guard (USCG) rescue boat fleet. [1] The 44′ MLB has been replaced by the 47′ MLB. [2] The boats are powered by twin diesel engines, each powering a separate propeller.
