Marine engines and power systems can be quite complex and varied. Here we demystify them and explain the basics behind what powers smal, boat to help you better understand all the types of motorboat engines out there on the water. But sorting through all the different options can be quite difficult.

Which is best for the type of boating you enjoy? Is newer technology necessarily better? And which engine and drive systems are evolving the fastest? Strictly speaking, bosts engine is what creates power and the drive system is what transfers that power into thrust. So logically, small boats with inboard engines meaning want to distinguish between the two.

Outboard Engines An outboard engine sits on the transom of a boat and has its own self-contained drive. The powerhead or motor, in the case of an electric outboard is protected by a removable cowl.

A motor mount just below the powerhead bolts or clamps onto the transom of the boat, and the midsection of the outboard, which encloses the drive shaft and exhaust housing, has a lower unit bolted onto the. Most of the time the lower unit swings a propeller for propulsion, but in some meajing the lower unit houses a jet drive.

A lower unit with a propeller also incorporates a skeg, which offers it some protection from striking hard objects. Outboard engines boast a long list of advantages. A huge range of sizes is available, from small electric models which produce a fraction of a horsepower and are powered by a volt battery, all the way up to the largest currently offered, a semi-custom Seven Marine HP outboard. Outboards are also used by sailors, as auxiliary power.

What about the poor reliability, awful pollution controls, and high noise and vibration levels that older salts may associate with outboard engines? Stricter Small boats with inboard engines meaning rules and regulations forced outboard manufacturers to either shift to four-strokes or redesign cleaner, more efficient two-strokes decades ago.

And yes, two-strokes designed in recent years really were far more efficient, reliable, and environmentally friendly than old-tech two-strokes read DFI Direct Fuel Injection Two Stroke Outboardsto see how modern low-emissions two-strokes work. However, due to economic forces BRP discontinued Evinrude engine production enhines the last two-strokes small boats with inboard engines meaning in North America rolled off the production lines in Today, virtually every gasoline outboard on the market is a four-stroke and not only offers excellent reliability, small boats with inboard engines meaning also has vastly improved efficiency bkats is far more pleasurable to run than older outboards.

Naturally, there are some downsides associated with outboard small boats with inboard engines meaning. Enginea a 35 MPH cruise, the stern drive boat got 3. The outboard powered boat got only 3. Note that the outboard boat went 10 MPH faster at wide-open throttle, but matched at an equal speed, the stern drive proved more efficient. At best you can have two small platforms, one to either side of the engine, and on many watersports boats this is a significant disadvantage.

Small boats with inboard engines meaning, for the coming years we will still be seeing many of these engines on used boats. Submerged in Water? No Problem. Mercury Racing Optimax� Diesel? Yes, Diesel. In some cases, inboards also have an edge when it comes to meabing distribution.

Small boats with inboard engines meaning boat designers would argue that having inboards deep in the belly of a boat makes for a lower center of gravity and a better running attitude. That said, all hulls are different and different boats with different power systems can be designed wkth accommodate different weight distributions.

In some cases a manufacturer will modify a boat to sell it with inboards when it was originally designed for outboards, or vise-versa. There are, of course, some significant down-sides to inboard engines. Some exceptions include small boats with inboard engines meaning water ski and wakeboard boatsand some watersports-oriented runabouts.

Those for inboards consist of straight-shaft, stern enginse, pod drive, V drive, and in rare cases surface drives. Jet drives, you might remember, can be used with both outboards and inboards. Here are the basic characteristics of each: Straight Small Boats With Cuddy Cabins Usa Shafts The shafts come out through the hull-bottom of a motorboat, and steering is accomplished by directing thrust over rudders.

That means handling is commonly poor as compared to boats with articulating drives. Both gasoline and diesel straight shafts are available, but aside from dedicated water ski and wakeboarding boats where wake-shaping and locating the propellers as far as possible from people in the water are significant Small Boats With Inboard Engines Review concerns and a few mid-sized cabin cruisers where price is a big factor � diesels cost significantly more than gasoline enginesthere are relatively few gasoline inboard straight shafts on the market today.

Straight-shaft boats have relatively deep drafts, and if any of the underwater running gear gets damaged, the boat must be hauled out for dmall.

The engines in straight-shaft boats are fairly far forward, which can be advantageous when small boats with inboard engines meaning comes to weight distribution. However, this does tend to eat into cabin space. Stern Drives The engine is mounted near the transom of the boat and is attached to a drive system that goes through the transom.

Stern drives offer comparatively good fuel efficiency and good handling, especially at high speeds. At low speed, single-engine stern drives with single propellers as opposed to DuoProp or Bravo III driveswhich have inbpard, counter-rotating propellers, tend to wander and may be difficult to steer. Since the drive unit on a stern drive can be trimmed, running angle can be adjusted. At slow speeds draft can be engined, and you can bring the prop out of the water when beaching or mooring your boat.

On a new type of stern drive, the Volvo Penta Forward Drivethe lower unit and propellers face forward small boats with inboard engines meaning all other stern drives they face aft. This makes it an attractive option for water skiing and wakeboarding or wake-surfing boats, which have traditionally been straight-shaft inboards, because it moves the propellers forward by over two feet.

With the props this far forward and under the boat it seems very unlikely, if not impossible, for a watersports enthusiast to fall into the spinning propellers.

Stern drives have an awful lot of moving parts, are fairly complex, and have a well-deserved reputation for requiring more maintenance than most other drive systems. Compared to straight shafts they usually allow for more cabin space, and compared to stern drives they usually allow for better weight distribution.

The articulating drives, mounted forward of the transom, offer the very best handling of any type of inboard drive. They generally come with joystick controls and can spin in their own length or move the boat sideways. Pod drives offer an efficiency gain as compared to straight shafts. Many boats net a to percent fuel economy advantage. V Drives V drives allow for the engine to small boats with inboard engines meaning located far aft yet qith forward, and still have shafts that exit the boat's bottom facing aft.

This is advantageous since, being located all the way back near the boat's transom, they don't take up cabin space. Since the engines aren't located forward as with traditional straight shaft drives, the weight distribution meanning of straight shaft inboards are largely forfeited.

V drives are mostly seen on either mid-sized power cruisers and motor yachts where an small boats with inboard engines meaning is placed on maximizing the cabin's interior volume, or on ski and wakeboard boats where locating the weight aft helps create a large wake as well as eliminate the need for a motorbox in the center of the cockpit, yet inboard propulsion is still preferred over a stern drive.

The most common is an Arneson drive. Surface drives are usually found on extremely expensive performance-oriented dayboats like the Magnum 51 Bestiaor the Revolver Some, but not all, surface drives are articulating. Some others require a rudder. Handling for either tends to be difficult at low speeds, and handling in reverse is particularly problematic.

Draft is significantly reduced, as compared to other propeller-driven propulsion systems. Surface drives are designed to operate with half the propeller s out of the water, but at pre-planing speeds, the propeller s are fully submerged. As a result, some boats with surface drives have a very difficult time transitioning from pre-planing speeds to planing speeds. Jet Drives Jet drives utilize a water impeller and nozzle to create thrust, instead of swinging a propeller.

Jets are favored by some people on small runabouts since they eliminate all the dangers associated with propellers. They may inbboard utilized on larger motorboats where draft is a serious consideration; unlike most other drive systems they require water no deeper than what is required to float the hull.

There will be an adjustment period for boaters who are accustomed to other systems. To learn more about this propulsion system, read Jet Drive. To learn more about jet wigh in specific, read Jet Boatsand to learn more about those jet-powered personal watercraft, read Jet Ski.

Aug 23, �� As the names imply, an inboard motor is mounted inside the boat and usually at the hull. Gas versions feature combustible engines with cylinders. The outboard motor design means the engine is placed outside the boat, typically in the back or stern of the craft. Boating enthusiasts have varying opinions about which may be better, too. Jan 06, �� Inboard Engines Simply put, inboard engines are those that reside inside the hull of a boat. But here�s where things often get confusing: straight-shaft drives are commonly just called �inboards� by most people, yet stern drives and pod drives, which are all radically different propulsion systems, are technically also inboards.
