Outboard engines are mounted on the outside of the boat high on the transom and can be tilted completely out of the water making it very easy to perform maintenance and if need be replace. Both work together to propel the craft forward and reverse it on demand.
The engine turns a drive shaft that runs through the bottom of the hull and is attached to a propeller at the other end.
How does an inboard outboard motor work. An inboard engine works just like a car engine in terms of how it creates power and delivers drive to the boat. It is in the case of a gas or petrol inboard a combustible engine that has cylinders which fill with fuel and air. A spark ignites this fuel air mixture to create an explosion.
An inboard engine sometimes referred to as an inboard motor or as sterndrive is a boat propulsion mechanism that sits inside the hull of the boat permanently. The inboard engine is connected to a driveshaft which controls the direction of the propeller steering the boat. True Inboard vs IO.
Outboard engines are the idyllic choice for fishermen and light commercial inshore boats. Outboard engines are mounted on the outside of the boat high on the transom and can be tilted completely out of the water making it very easy to perform maintenance and if need be replace. With mostly positive attributes outboards do lack power and torque.
The answer to the question of how does an inboard boat transmission work considers the unique challenges of driving on the water and the relationship with the propellor. Both work together to propel the craft forward and reverse it on demand. With this system the motor is totally dependent of fresh seawater being present to provide proper cooling characteristics.
Fresh seawater is normally drawn by a belt driven pump from a thru hull fitting in hull of boat on inboards or by water pump in stern drive through the lower unit water passages on an inboardoutboard and then exits the boat through the exhaust. As the names imply an inboard motor is mounted inside the boat and usually at the hull. Gas versions feature combustible engines with cylinders.
The outboard motor design means the engine is placed outside the boat typically in the back or stern of the craft. Boating enthusiasts have varying opinions about which may be better too. When the lever for one outboard is set to the center position the boat is out of gear.
Push the lever forward and the boat goes into gear. It engages the transmission which relays the drive power from the engine outboard to the propellers. The transmission will also shift from forward to reverse changing the direction of spin or the propellers.
I believe the outboard measures the cycles of the ac then divides to get the rpm. Most 4 strokes measure the of times the coil is asked to fire then calculates by the of cylinders. Learn the difference between an outboard and an inboard outboard motor.

Inboard engines are mounted inside the hulls midsection or in front of the transom. The engine turns a drive shaft that runs through the bottom of the hull and is attached to a propeller at the other end. In this video we look at the inner workings of an outboard motors gearbox.
This includes the drive shaft shift linkage dog clutch forward and reverse gea. A sterndrive or inboardoutboard drive IO is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit outdrive or drive leg lies outside the hull.

There are a few engineering details youll need to work out but it generally boils down to a enclosed well with a transom set at the proper height for the engine and well under the boat so it doesnt ventilate a door or plug to seal the hole in the bottom of the boat when not in use and sufficient enough ventilation for the motor to breath and stay cool without getting swamped or. So unlike automotive applications where air is the primary element in extracting heat from the engine in marine applications we count on seawater or lake water or river water to do the job.
This seawater gets pumped through the heat exchanger on your engine and via convection pulls the heat away from the tubes inside the exchanger. Most inboard engines are diesel engines which are more reliable save money are cheaper to maintain and eliminate the risk of gasoline. The weight of the engine is at the bottom of the ship so it is a good ballast for improving the stability of the ship.
