What is the difference between inboard and Io?

A stern drive IO, also known as an inboard outboard, has an outboard lower unit connected through the transom of a boat to an inboard gas/petrol or diesel engine. Widely available on boats under 30 feet (or 9 meters), sterndrive inboard outboards have a lot of advantages when compared to inboard boat motors.

What does IO stand for on a boat?

A sterndrive or inboard/outboard drive (I/O) 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.

What is an IO boat engine?

Stern drive engines, also called inboard/outboards (I/O) are a combination of the inboard and outboard engine. The motor is in under the transom of the boat and the drive unit is tucked beneath the swim platform. The motor, like most inboards, is a marine adapted automobile engine mounted inside the boat.

Which is better sterndrive or inboard?

Sterndrives will go faster than an inboard with the same horsepower and even use less fuel. On the other hand, inboards will hold a speed more easily than a sterndrive. Sterndrive's put out great wakes for wakeboarding; inboards create flat wakes for waterskiing.

What is difference between inboard and inboard 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.

Which is faster inboard or outboard?

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.

Is an inboard or outboard better?

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.

Are inboard motors safer?

It is true that you can tow a wakeboard behind a variety of different boats with the right equipment, but before you delve into safety tips there is one important thing every boat driver who plans to tow a rider should know: Inboard boats are the safest style of boat for pulling a rider.

What makes a boat an inboard?

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.

Is sterndrive the same as inboard outboard?

Sterndrive boats

For this reason, sterndrives are also referred to as inboard/outboards. Sterndrives employ an inboard engine, often a marinized automotive engine, and drive the boat via a lower unit similar to outboard motors.

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.

Why do boats have 2 motors?

With two engines, your boat is producing a lot more torque and the result is better time to plane, especially with the boat fully loaded. Top end performance is a result of horsepower. With a total of 600hp vs 430hp, the boat is going to go faster with more horsepower.
