Inboard outboard vs outboard boat motors10/5/2023 ![]() Since there is no physical access to the motor from within the boat, these are only operated from the helm. It has more horsepower, a higher torque, and can typically accelerate faster. Inboard motors are close siblings to the engine you’ll find in a car. An inboard motor often has a separate rudder that steers the boat.Ī big difference between these two motor types is their mechanical properties. From the exterior of the boat, all you’ll see is an angled shaft with the propeller at the end.įrom inside of the boat, you won’t see the motor at all. The bottom of the boat near the center will house the motor. What Is an Inboard Motor?Īn inboard engine, on the other hand, has most of the components inside of the boat. All the components are mounted outside of the boat, hence the name. Outboard motors are the only option that can be seen while sitting in the boat. You’ll see the large motor component attached to the rear of a boat, and a lower unit will go straight down that has the propeller attached to it. You can recognize an outboard motor quickly on a boat. Larger options are almost exclusively operated through the helm. The second option is used mostly for smaller boats and smaller motors. ![]() There may be a throttle to adjust the speed, or the motor might be a single speed. In the second configuration, you’ll use a tiller that’s mounted directly on the motor. There is a throttle and steering wheel that operate the motor remotely. In one way, the motor is controlled through the helm. Depending on the size and orientation that you opt for, there are two ways to operate these motors: What Is an Outboard Motor?Īn outboard engine is an independent motor that mounts on the rear of your boat. In this piece, we’ll explain everything you need to know about an outboard and inboard motor, and we’ll help you pick which one is right for you. If you want to make the right choice, then you’ll need to learn more about both motor types. The tough part is that outboard and inboard motors are both valid choices and they’re both designed for different people. It’s the heart of your vessel, so you want to avoid making the wrong choice. All 3 are fine and service millions of boats each, but one is probably better for the type of boating that youdo.A boat’s motor is a huge investment. So you have to choose based on the type of boating that you do, your budget, and also what is popular in your area (this is important when looking for a mechanic). Also handling an inboard in reverse takes more practice since the prop is fixed and the rudder is not effective until water flows over it, either from prop blast or motion. Also it is often hard to trailer an inboard since the trailer has to be higher to accomodate the prop/rudder. The disadvantages are that the prop is fixed, is deeper, and can’t be tilted up like the outboard or I/O. Inboards probably have the best combination of engine placement, inside where it’s accessable, farther forward for good weight placement, and weight (they can be lighter than I/Os). ![]() ![]() However they are very expensive and heavier than 2 cycle engines. They are powerful, quiet, have outboard convenience and are now available in high power versions (200+ HP). The new 4 cycle outboards may have it all in one package. Some folks disconnect the pumps and mix the oil and gas manually. 2 cycle outboards, where the gas and the outboard motor oil are mixed together almost all have automatic mixing pumps (above 40 HP or so) that take care of this chore, but have been known to fail, with catastrophic results. The disadvantages are that outboards have become as complicated as spacecraft and unless you are a good mechanic, you can’t do much if any, of the maintenance yourself. A hole, or tear, in it can sink the boat.Īn outboard is probably the most expensive, can be tilted clear of the water, and has the best horsepower to weight ratio. Also, the rubber bellows that encloses the drive shaft, as it comes out of the boat and into the outdrive is usually at least partly submerged. The disadvantages are that the outdrive can’t tilt clear of the water, so if you boat in saltwater the aluminum outdrive is always submerged and subject to corrosion. You can get to the engine pretty easily in most boats. I/Os are the often the least expensive, and you have the advantage of having a realtively car like (simple) installation. What is better? An I/O, an inboard, or an outboard? What’s cheaper?
