Family boats with inboard power are almost always equipped with a sterndrive (sometimes called an inboard/outboard or I/O) powertrain, which combines an automotive-type engine mounted inside the boat with a steerable and trimable drive unit mounted on the stern (the back) of the boat.
How do I know if my boat is inboard or outboard?
The difference is actually within the words; an inboard engine sits within the structure of the boat and is not visible whereas the outboard engine sits outside the structure of the boat and is clearly visible at all times.
What is an inboard boat?
An inboard is a four-stroke automotive engine adapted for marine use. Inboard engines are mounted inside the hull's 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.
What is better inboard or outboard?
Inboard motors generally last longer than their outboard counterparts. You can squeeze roughly 1,500 hours out of an inboard before necessary maintenance. Outboards, on the other hand, last about 750 hours on average. So, the inboard option means less maintenance (nearly half) even though they cost more initially.
Whats the difference between an inboard motor and an outboard motor?
What is the difference between an inboard and outboard motor? An inboard motor is permanently placed inside the boat and helps power a prop shaft through the hull. An outboard motor is placed outside the boat, generally hung by clamps at the stern of the boat.

ADVANTAGES OF INBOARD ENGINES
Inboard engines are favorites for water sports like wakeboarding and waterskiing, especially with multiple skiers, as they have better wake control, major towing power and a clear transom for tow ropes. A lower center of gravity also helps to cut through heavy ocean waves.
How much is a new inboard boat motor?
Inboards typically require between $1,000 and $1,500 in costs. As long as the boat is equipped with an engine that is capable of 5 to 10 horsepower, nothing much can prevent a sailboat from docking successfully. Easy to maintain, the engines are easy to run and inexpensive.
Is a pontoon an inboard or outboard?
Pontoon boats, in the main use outboard motors, but you will see some for sale which do actually use an inboard motor. Most of the time, though, it will be an outboard motor.
Why do ocean boats have outboards?
Compared with all three other propulsion systems that basically have an engine in the boat, using multiple outboards makes the boat faster because of a beneficial power-to-weight ratio and, in most cases, the outboards are more fuel-efficient.
Can a pontoon boat have an inboard motor?
There is a small number of inboard pontoon boats on the market but it's not the popular engine choice for this type of boat. Just the same, you will find that all towboats have inboard engines.
Are outboards faster than Inboards?
Pound for pound, outboards deliver more power and speed than inboards. Outboard boats are several hundred pounds lighter, and less weight means your boat is faster, easier to tow, and more fuel efficient.
What is sterndrive vs inboard?
Inboard propellers are tucked up underneath the boat, which can be much safer than a sterndrive tilted up; but without a tilt up mechanism, an inboard engine has a larger draft. Since a sterndrive boat has the equipment on the back of the boat, it allows more room onboard than an inboard boat.
Is sterndrive the same as inboard?
Outboards provide more room in the boat because they are installed on the transom, outside the boat. A sterndrive 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.
How do you turn an inboard into an outboard?
How to Convert a Boat From Inboard to Outboard
- Turn off the fuel valve and disconnect the battery negative cable. ...
- Install the engine hoist and pick up with it just enough to keep the slack out of the chains. ...
- Install the motor bracket to the transom. ...
- Lift the bracket back into position and install the bracket bolts.
What does outboard mean on a boat?
An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom.
What is better in salt water inboard or outboard?
Inboard engine boats are better suited for performing water sports. As well as powering large vessels that require a lot of horsepower to move the boat. Outboard engine boats are better suited for shallow water, salt water, and pontoon boats.
Can you use an inboard outboard in saltwater?
It doesn't matter what propels your boat — inboard, outboard, I/O, jet drive — nothing on your boat that comes in contact with saltwater is immune to its corrosive powers. Different propulsion systems may be attacked in different spots, but your power plant needs protection.
Why do Florida boats use outboard motors?
Outboard motors are easy to maintain when compared to inboard motors because of their positioning. They also maximize the usable space inside the boat.
Do boats come with motors?
You may just start to notice the newer model boats will come with outboard motors as a standard. In the end, you may find a better value in the outboard motor like many others have. It makes buying a boat and enjoying your best boat life, a little easier on the wallet all around.
Do deck boats have inboard motors?
Deck boats, on the other hand, offer two engine options. These options are outboard and I/O or, inboard/outboard. Unlike pontoons, smaller deck boats can facilitate larger engines. Depending on your preference and how you choose to use the boat, you may prefer one over the other.
What is inboard on a pump?
Inboard: The relative position of components in a pump. Inboard refers to components that are closer to the pump coupling, while outboard refers to those further away from the pump coupling. Also known as “inboard side” or “inboard end”.
How much does it cost to engine swap a boat?
So if you are one of these lucky ones, your engine replacement will cost around $5,000 if you either want something smaller or get a good deal. $10,000 is the top of the range estimate you will have to pay in case you are looking for more power, and/or fancy one of the bigger manufacturer brands.
Why do outboard motors cost so much?
Boat motors (outboards) are expensive because they are equipped with high-quality parts that are not only designed to resist constant working at max RPMs but made with materials meant to resist corrosion well. All of this needs significant work in R&D (more money), resulting in a pricey product.
Why do boats have 4 outboard motors?
Multiple outboard motors increase the holeshot power. If a hull is fitted with 1000 horsepower, it will be faster than 750 horsepower. With modern motors, you will get lighter motors, which will make it easier on the boat. Today's motors are also small in size, so you don't have to worry about the surface area.
