![]() ![]() Compare for yourself the differences between outboard deck boats and inboard outboard deck boats. Many boaters have strong opinions on which works best for them, and you should try to form your own. Ultimately, the choice between an inboard/outboard and an outboard motor comes down to your personal preference. On the other hand, inboard/outboard engines may have a longer lifespan, allowing for less overall cost in the long run. They’ll also be easier to move, replace and upgrade. When considering down-the-road costs, such as maintenance, sterndrives may require more attention due to their many moving parts – a prospect that is slightly more difficult than with an outboard, as outboards are far easier to access and service with the full engine outside the boat. When it comes to upfront cost of the two engines, an outboard will typically be cheaper than an I/O engine, although upgrades in outboard technology has made it so the two price points are often comparable. Additionally, an I/O engine will often be quieter, allowing for a more pleasurable cruise in some instances. For those who plan to lounge and try to make the most of the boat’s interior, the uncluttered look is both more aesthetically pleasing and more functional. For many boaters, having a sterndrive is key as it allows for full use of the boat’s stern because it’s not taken up by an outboard. The most crucial element of choosing an engine for your boat is thinking about what you plan to do with it. The style of engine you choose may also be impacted by where you plan on cruising – outboards can tilt up in the shallows, allowing access to sandbars and beaches, while a sterndrive’s higher weight can mean that it’s a more pleasant ride in rougher seas. Each motor has its benefits for different activities and lifestyles, and you should carefully weigh those factors before making your decision. ![]() There’s no one right answer as to which motor is the right choice for you. The economy difference between a V6 an a I4 are very marginal. Inboard Outboard vs Outboard Boat: Which Should You Buy? Re: Fuel economy I/O Vs Outboard New outboards are suppose to be pretty efficient. This kind of engine has become a popular option for many boat styles and might be right for you. On most recreational boats, the style of inboard motor is an inboard/outboard motor, or I/O, which combines the engine mounted inside the boat with a steerable drive unit mounted on the stern – a sterndrive. Inboard engines are contained within the structure of the boat and provide thrust and steering from the bottom of the hull. These types of engines are typically right at home on fishing vessels, as well as pontoon boats. Outboard engines provide steering control in addition to propulsion by pivoting and controlling direction of thrust. ![]() Outboard motors are self-contained units that include the engine, transmission, and propeller, mounted on the boat’s stern and sitting outside the hull. With the layout and use of the boat hinging on the type of propulsion it runs, a careful consideration of which is right for you must include a more detailed look at the engines themselves. The downside to Inboard Outboard boats is that the engine compartment takes up valuable real estate in interior compartments. By having the engine enclosed and insulated it also make the engine much quieter resulting in a more enjoyable experience. This allows a full back deck for lounging, watersports, or a swim platform. Outboard motors are the most common marine propulsion type for small watercraft because of their compact design. thanks of the range estimates are with a 10% reserve of fuel, thats 7.4 gallons of reserve with my Moeller 22 gallon deck tank.Inboard Outboard boats have the engine in a compartment inside. Which works out to a range of 168 miles with my extra 22 gallons of fuel. at WOT I’m burning 14.5 gph at 39mph which works out to 2.68 mpg. If I knew I was going to be operating at sea level or low altitude I’d throw the OEM impellers back on.Įdit: Should have thrown this in there. With the high altitude impellers my solo mileage dropped to 3-3.1 mpg=194 mile range (w extra 22 gallon tank) a totally fair trade off for the huge improvement in performance, toss in two adult guests and their gear and the mpg drops to roughly 2.8 mpg=181 mile range (with extra 22 gallon tank) All at best cruise speed of roughly 25-28 mph. Normally I have about 500# of gear ( that includes the trolling motor and batteries and the live well full which is 216# of water) at full fuel and me on board I was getting 3.375 mpg =218.7 mile range (with extra 22 gallon tank) all with the stock impellers. In boat test of my boat they only had three people, 50% fuel =150#, 50 lbs of gear and the mpg was 3.5. For my boat the mpg is really close to the test mag’s mileage. ![]()
