The I/O is in a less ideal position because it is at the bilge of the boat where it can be damaged by water and moisture vapor. The I/O motors and inboard motors share similar problems. The engine housing fully seals the engine and protects it from the environment while providing the ideal environment for the electronics and mechanics inside the motor. Outboard motors are often preferred because you can work on it from inside the boat regardless if you’re in the water or not. This is because the outdrive is based off the lower unit of the outboard. What makes the I/O a nice hybrid is that it uses a similar steering system when the power is not on. Some joysticks are available on inboard models as well. Some I/O systems are equipped with a joystick control, which can simplify docking, but not all models have this feature and the ones that do can be pricy. Inboards are difficult to steer unless you are applying the thrust. The outboard has the advantage because the integral skeg and directional thrust lets you maneuver easily without power. Inboards and outboards have different powering systems, which will affect how you will be able to control your vessel at lower speeds. This hybrid model is usually mounted at mid ship that drives a propeller shaft that passes through the bottom of the hull. You may not know you’re looking at it, but the inboard outboard (I/O) is in the same general area as the outboard, though it’s usually tucked under a swim platform. The outboard also takes up quite a bit of space IN THE KNOW WITH INBOARD/OUTBOARDS This will naturally make the boat heavier, requiring more fuel to power it. If that’s the case, a boat is going to need a thicker, healthier transom. One of the biggest drawbacks, however, is that in order to get the power that the I/O has might take several outboards. It’s also much easier to service an outboard motor, and they have a good reputation with boaters for being reliable. If you choose to replace the motor later for a larger, upgraded model, changing the outboard engine is a cinch. This way your engine will not be sitting idly in the water where water inhabitants can attach themselves to the propellers. This is extremely beneficial for storage in the winter or even at the docks. Many boaties find the easily-accessed mounting position of the outboard appealing because it allows them to lift the engine completely out of the water while it’s not in use. They are popular among boaties and are often the default choice for both fishing and recreational and light commercial inshore boats. You’ve probably seen outboards on the boats of friends and family. Because the transmissions are inside the vessel, more cabin space is allotted. They are more expensive than an outboard motor and harder to load onto a trailer, but because they were modeled after car engines, they are more fuel-efficient, have better horsepower and more torque. Though inboard motors require a large box in the middle of the boat, which will keep the engine, they are much quieter than outboards, which is great for entertaining. There are a few major drawbacks with inboards, but many boat owners overlook key features. If a heavier vessel chooses an inboard, they will need a motor larger in size and weight, which will not be appropriate for mounting at the aft end of the hull. These types of motors are popular with slalom skiers as they produce a smaller wake as well as fishing boats in heavy seas because they have a low center of gravity. INBOARD IS INĪn inboard will use a separate rudder to enable the boater to steer. Then read on and find out which engine is best suited for you and your needs. It’s all a matter of preference and what you plan to do on and with your boat.īefore you make a decision, you should really assess what your plans are for your boat and how much you know about either engine. You may already have set notions about one or the other, but the fact is that one is not really better than the other. When choosing the right boat, you’ve probably noticed three different types of engines: the outboard, inboard and inboard/outboard (I/O). This will ensure that you look like a pro when the topic comes up! We have seen the appearance of inboard motors take over the industry.īUT before you answer that question, here are a few key bits of information you will need to know. So it’s about time we pose the question: Outboard vs Inboard?Īs technology progresses trends follow.
