Small boats with outboard engines and personal water crafts (PWC) tend to ingest water simply because they run in and around it. During a rollover, or when a wave washes over the craft, its engine can hydrolock, though severe damage is rare due to the special air intakes and low rotating inertia of small marine engines.
When looking at diesel driven vessels, the engines induce large accelerations that travel from the foundation of the engine throughout the ship. In most compartments, this type of vibration normally manifests itself as audible noise. The problem with diesels is that, for a given size, there is a fixed amount of power generated per cylinder.

Additionally, the MHD design eliminates many of the wear and friction pieces of the drivetrain with a directly driven propeller by an engine. Problems with current technologies include expense and slow speed compared to a propeller driven by an engine. [8] [9] The extra expense is from the large generator that must be driven by an engine. Such ...
With the development of the marine steam engine, their boilers also required a continual supply of feedwater. Early boilers used seawater directly, but this gave problems with the build-up of brine and scale. [23] For efficiency, as well as conserving feedwater, marine engines have usually been condensing engines.
Using a new state law, the Town of Port Royal is pursuing tough new mooring rules to keep derelict boats at bay as it prepares to pour nearly $1 million into building a new shrimp dock.
A post shared on Facebook claims Tesla CEO Elon Musk announced the creation of a water-powered car engine. Verdict: False There is no evidence Musk has announced such a creation. Fact Check: Tesla ...
An early engine of the company was the Model 102, developed from the Marston models of the 1930s. The Model 102 engines were fairly large and featured an integral engine cylinder block and head, with a water-injected exhaust. Some Model 102 outboards had a 13-inch-diameter (330 mm) propeller, gaining the moniker of "The Barge Pusher".
