Anyone looking to purchase a boat has an array of choices when it comes to the kind of engine that they want powering their new vessel. These engines, also known as a drive or motor, use the same principles as an internal combustion engine, with the difference being that a boat motor turns a propeller as compared to a car engine that turns a set of wheels.
Whether it’s for racing boats or recreational vessels, the motor can make a big difference in the speed and stability of a boat, and is an important decision to make before finalising a purchase. These are the common types of motors found on modern boats.
An inboard drive is a motor that is enclosed inside the boat, with the shaft, rudder, and props located on the bottom of the vessel, which leaves the transom clear. They can either be powered by diesel or gasoline, and come in single or twin-engine varieties. A marine V-drive motor, for example, is a modified version of a conventional inboard drive that is located a bit closer to the stern of the boat than is typically found. They can range between 1 and 12-cylinder models, although 4 and 6-cylinder variants tend to be much more common.
These are the most common types of boat motors, and can be found on most freshwater fishing boats and recreational vessels, the kind that can be taken out on the water for a day of fishing or kicking back with a game of online casino Philippines. These are self-contained units that are directly mounted on tot he rear wall, of the boat, also known as the transom. Each unit has a propeller, motor, and steering control, with the steering cables attached to the steering wheel through a pivot that allows the entire motor unit to turn and change the direction often boat. This system also makes it easier to remove the boat from the water, as the motor can simply be pivoted vertically.
Sterndrives are a mixture of inboard and outboard motors, and are usually mounted inboard forward of the transom, and the shaft that goes through the transom to the drive unit that is located below the water. Similarly to an outboard motor, the unit can be pivoted upward to allow the boat to be taken out of the water easily.
These are specialised motors that are most often utilised by performance vessels. They consist of an inboard engine that drives a propeller that pierces the water to provide thrust, meaning that the motor works both in and outside of the water at the same time, making use of the planing wake of the boat. These are the drives used when wanting to gain real speed, and are found commonly in speedboats.
Found in either large boats or personal watercraft, jet drives completely replace the propeller, and use high-pressure air that is forced out of the stern of the boat. The water jet draws water beneath the hull and pushes the boat forward, allowing them extremely fast acceleration
