The advantages of a sterndrive over an outboard engine are sterndrives have more horsepower and allow for a more attractive transom as the engine is hidden beneath the boat. They are also easier to fish on. The advantages a sterndrive has over an inboard are sterndrives have no need for a prop shaft or rudder system making it easy to trailer and operate in shallow water.
Sterndrives also allow for more space in the interior passenger cabin of the boat as the engine is mounted all the way in the back of the boat. Login Register. About Us Contact Us. Sell A Boat.

An inboard engine will go through very challenging environments, where an outboard engine will fail. For example, if a boat with the same weight and carrying capacity was fitted with the two engines for comparison, and then taken through a storm, the inboard engine will be more reliable. The outboard engine may stall or blow out,while the inboard engine chugs along comfortably. Therefore, if you are running a boat that goes for long distances and moves through the challenges of the high seas, then using a inboard engine will give you better reliability than an outboard engine.
As a rule of thumb, you need to know the purposes of the boat and then decide on which engine will be more reliable. If you just want a recreational boat to run along the harbor over the weekends,then go for an outboard engine. If you are a commercial fisherman who spends a lot of time out in the water under tough conditions, then go for an inboard engine.
In order to properly address this question,let us look at some of the basic and important aspects of inboard motors. This is one of the main reasons why large boats are fitted with inboard motors. An inboard motor will propel a boat through tough water conditions where an outboard motor will not. On the other hand, since the weight of the engine, especially when located in the middle section, makes the boat sit deeper in the water.
This produces a higher drag and affects the cruising and top speed. This is mainly due to the positioning of the engine. It is costlier to maintain an inboard motor, although this cost is alleviated by the cheaper costs per part. They are fitted in the boat and do not affect the outward appearance of the boat. The fact that it cannot be trimmed out of water means that the pilot has to be very careful when sailing through shallow waters, or else he risks running the propellers into rocks.
An outboard motor can be trimmed and is therefore much safer in shallow waters. The motor is perennially bolted to the inside of the boat and cannot be removed for storage when the boat is not in use. This means that during winter, it will be exposed to ice. When in saltwater, the motor will be exposed to the corrosion of the salt. The engine box will therefore take up a lot of cockpit space.
So weighing up the pros and cons of both inboard and outboard motors, one would have to say the inboard motor is better than an outboard one however, this is based on particular circumstances. You only have to remove the cowling to expose the motor and you can easily maintain it. The inboard motor requires a much more complicated process. The only thing required is to know how much trim is required and you can trim the motor.
This also allows outboard motor boats to sail through shallower waters than inboard motor boats. If you are operating on a river, then this is the motor that you should have. This is further supported by the fact that you can trim the motor so that it lifts the hull from the water, reducing the drag and making the boat speed along at a faster clip.
An outboard motor can be trimmed out of the water, or removed entirely and stored safely away from saltwater or winter ice. Inboard motors have to remain on the boat, exposing the engine parts to the saltwater and winter ice, and this makes them corrode much faster. The cockpit can therefore be used for various reasons, such as storing fishing poles, etc. Here are some examples:. Suzuki is popularly known to produce outboard engines of note. The DFA is one of their flagship outdoor engines,ranging high in the horsepower game.
It has a huge 4. For all single-engine boats,the negation of negative torque is very relevant and the DFA excels in this aspect. An Aluminum Gaudet 38 was propelled by Quad s to speeds of In keeping with the Suzuki modusoperandi, the DFA has a lot of power per buck used. It has now become the norm for outboard motorboat designers to stretch the center console quite a bit. Some go as far as 50 feet, with battle-wagon express boats being converted from inboard engines to outboards.
In order to cope with this growing trend, Yamaha went and designed an engine that can propel a boat of 50 feet or more. This is the horsepower XTO Offshore. This is a 5. The XTO is a giant, with an integrated power steering, and weighs at about pounds — a single pound short of 1, pounds. However, some builders, as seen in the Scout shown above, have gone ahead and hang up to 5 of these big fellas on the stern. Yamaha says that quad XTO configuration can propel a foot Regulator center console to a max speed of One the other hand, you can opt for a single XTO having horsepower twins; a single XTO will propel a foot Sportsman boat at speeds reaching 55 mph and consume fuel at a rate of 2.
These small engines are targeted at the rich billionaires who have a Yacht or two or those who are in the import-export business and might need a small dinghy or sailboat to carry their wares.
The comes with a WH lithium battery and can go for a full 6 hours when running at half throttle. This means that you can travel 18 miles on water, using an average weight dinghy. Although the Torqueedo is ideally targeted at dinghies and small sailboats, it can also be ingenuously used as a kicker for a small powerboat or a trolling motor.
It is quite silent, emitting only 33Db of noise. It weighs less than 40 pounds so you can easily carry it along. If you want to go for long distances, pack a solar panel and use it to charge the battery as you go along. Does anyone doubt the Sea Ray? Actually,the brand is one of the most sought-after, according to the Ranker List.
Another indicator of the popularity of this inboard motor boat is that the dealers rank among the top dealers in the world. They produce inboard motor boats ranging from the foot Bowriderall the way to huge foot Yachts. Chaparral is another brand that makes boats with inboard motors. Apart from the craftsmanship of the boats, the company insists on having the best engines running in the belly of the boat.
As far as inboard motor boats go, this is one of the best that you will find on the market. It has won several engineering and innovation awards, taking the helm in 5 of the awards for the last 6 years. Their manufacturing plant in Vonore, TN has even won awards for the use of advanced technology in manufacturing. Inboard motors, for example, tend to last longer than outboard motors. And maintenance requirements, based on hours of use, often favor the inboards.
Inboards on average can run 1, hours before tune-ups, while the outboard counterparts typically run hours before service is needed. But buying the inboard motor will cost you more upfront and can require more expensive insurance coverage. Even those high-performance boats are rolling off the production line with outboard power. SSI , indicating the boat industry has sold more outboard motor-powered crafts over the last few years.
More specifically, there were , outboard boats sold in and , in As with any boating decision, what kind of motor design you decide is best for you will be determined by your frequency and use of the boat, along with your budget. 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.
