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 ...
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.
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 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.

Volkswagen Marine 3.0 litre V6 TDI 265-6 marine engine.This is a marine-modified version of Volkswagen Groups 3.0 V6 24v TDI CR automobile engine.. Marine automobile engines are types of automobile petrol-or diesel engines that have been specifically modified for use in the marine environment.
With the propeller pushing mostly air instead of water, the load on the engine is greatly reduced, causing the engine to race and the propeller to spin fast enough to result in cavitation, at which point little thrust is generated at all. The condition continues until the prop slows enough for the air bubbles to rise to the surface. [23]
A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is ...
