Inboard boat engines5/18/2023 These days inboard power is most popular on watersports tow boats designed for wakeboarding and wakesurfing, where placing the prop deep in the water under the boat produces a clean wake and keeps the prop away from the person behind the boat. Still, have questions? Contact our sales team and we’ll get you going in the right direction.A V-drive and a direct drive are both inboard propulsion systems, which means the engine drives a propshaft that passes through the boat bottom, with the propeller positioned under the boat and steering accomplished by a rudder. Depending on your budget and how you’re going to use your boat, either of these will get the job done and give you an enjoyable time on the water. These are just a few examples, and as you can tell, there are plenty of pros and cons to each propulsion system. Whether you choose a sterndrive or an inboard engine, both can provide great performance on the water. It all comes down to the type of boat you are looking for and the purposes you need it for. Now that you know the difference between a sterndrive and an inboard, it’s time to make your decision. They’re great for small boats but can also be used on larger ones. Electric DrivesĮlectric drives are becoming increasingly popular because they are very efficient, quiet, and require minimal maintenance. This is an ideal option for shallow water vessels or those with limited space. Jet drives use an underwater jet propulsion system that pushes the water out of the back of the boat instead of using propellers. These are a popular choice for smaller vessels and fishing boats because they are easier to access, service, and maintain than other systems. Outboard Motors are external and attached to the back of the boat. Other systems include outboard motors, jet drives, and electric drives, but sterndrive and inboard are very common. Sterndrive and Inboard are not the only types of propulsion systems available for boats. Since the motor is deep in the hull of the boat, it improves stability because it lowers the boat’s center of gravity. While sterndrive boats allow a smooth ride when trimmed up, larger boats with inboard engines can have a smooth and stable ride as well. Since a sterndrive boat has the equipment on the back of the boat, it allows more room onboard than an inboard boat. 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. However, sterndrive motors are easier to get to. Sterndrives can, at times, have higher maintenance requirements than inboards. Maintenance Requirements Between Sterndrive and Inboard With a sterndrive boat, reverse thrust is directional. Inboard boats go in one direction in reverse no matter what the position of the wheel. Sterndrives put out great wakes for wakeboarding inboards create flat wakes for water skiing. On the other hand, inboards will hold a speed more easily than a sterndrive. Sterndrives will go faster than an inboard with the same horsepower and even use less fuel. Sterndrives draw less when slightly tilted up. However, inboards draw less than a sterndrive does if the sterndrive is down (inboards need less water to float). Trimming down allows quicker acceleration. It also allows smoother rides when trimmed up. This allows you to raise the sterndrive when loading/unloading or when in shallow water. Sterndrives provide the boater with a versatile range of trim. When comparing these two systems, it is important to look at the pros and cons of each. Pros and Cons When Comparing Sterndrive and Inboard The propeller then pushes the water past the turned rudder and turns the boat. The boat is steered with a rudder when the steering wheel is turned by the captain. The driveshaft goes from the transmission to a propeller outside of the boat. No rudder is needed.Īn inboard is a marine propulsion system that is enclosed within the hull of the boat - it is usually connected to a propulsion screw by a driveshaft. When the captain turns the steering wheel, the entire drive turns. The drive unit is both the transmission and propulsion. Sterndrive and Inboard Motors Explainedįirst of all, let’s start by explaining what exactly sterndrives and inboards are.Ī sterndrive is a marine propulsion system that is attached to a sterndrive, also known as an outdrive. Both have pros and cons and are two completely different machines. In this post, we’ll present the facts and let you decide on the rest. Stay tuned to learn more!įor years there have been debates about whether sterndrives or inboards are better. Do you know the difference between a stern drive and an inboard engine? If not, don’t worry – you’re not alone! In this blog post, we will discuss the differences between these two types of engines.
