Sterndrives will go faster than an inboard with the same horsepower and even use less fuel. On the other hand, inboards will hold a speed more easily than a sterndrive. Sterndrive’s put out great wakes for wakeboarding; inboards create flat wakes for waterskiing.
Is sterndrive the same as inboard?
A sterndrive is a marine propulsion system that is attached to a sterndrive, also known as an outdrive.An 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.
Are sterndrive boats good?
The advantages to a sterndrive are the vessel design and ability to offer larger horsepower options. With a lot of fishing boats, the rear deck space and access is important. For those looking to do water sport, it can be beneficial having a rear swim platform without a motor protruding in the middle.
Is sterndrive or outboard better?
Fuel Efficiency
If gallons per hour are important to you, consider a modern four-stroke outboard, as they are often the most fuel efficient. While RPMs at a cruising speed tend to be higher with an outboard engine, they still beat sterndrives in fuel efficiency — one of the pros of outboards on bowriders.
Is Stern drive the same as inboard outboard?
Sterndrive boats
A sterndrive is an arrangement that combines the elements of inboard and outboard systems. For this reason, sterndrives are also referred to as inboard/outboards. Sterndrives employ an inboard engine, often a marinized automotive engine, and drive the boat via a lower unit similar to outboard motors.
Are Inboards better than outboards?
Inboard motors generally last longer than their outboard counterparts. You can squeeze roughly 1,500 hours out of an inboard before necessary maintenance. Outboards, on the other hand, last about 750 hours on average. So, the inboard option means less maintenance (nearly half) even though they cost more initially.
How long do stern drives last?
It’s also common to expect between 10-15 years out of a well-used sterndrive and transom assembly, and then it’s a matter of continual repairs or replacing it once and for all. Sterndrives are a faster and more efficient design, as they are mounted to the rear and produce less drag.
Are outboards faster than Inboards?
Pound for pound, outboards deliver more power and speed than inboards. Outboard boats are several hundred pounds lighter, and less weight means your boat is faster, easier to tow, and more fuel efficient.
What’s a sterndrive boat?
A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit (outdrive or drive leg) lies outside the hull.
Which MerCruiser outdrive is best?
With over 20 MerCruiser sterndrive systems to choose from, the Bravo Series and Alpha One outdrives clearly stand out as the top choices for boaters. The power of a sterndrive vs inboard engine on a boat can not be matched when it comes to MerCruiser outdrives.
Are stern drives good in saltwater?
Technology has also improved corrosion protection – especially in the saltwater environment – for sterndrives. “There’s no doubt earlier closed-cooled sterndrives suffered terribly from corrosion,” admitted Ray.
Do boat engines have catalytic converters?
NSCR Catalyst for Marine Engines
Engine exhaust has been effectively treated by catalytic converters since the 1970’s when the first automobile catalysts were placed on cars. Now EPA has a new requirement for catalytic converters on spark ignited, marine gas engines.
Are V drives better than outdrives?
A V-drive is more efficient in delivering horsepower to the prop, losing only 8 percent, while a sterndrive loses 13 percent. Yet, all other things being equal, a sterndrive is faster and more fuel-efficient.
How does a sterndrive work?
When you power up your engine and pull away from the dock, you set in motion a lot of activity at the stern of your boat. You push the throttle, engaging the prop. Power from your engine is transferred to the sterndrive via the drive shaft. Exhaust is pushed from the engine and exits at your prop.
Are outboards better for salt water?
As well as powering large vessels that require a lot of horsepower to move the boat. Outboard engine boats are better suited for shallow water, salt water, and pontoon boats.
What is easier to maintain inboard or outboard?
Because the entire engine is outside the boat, an outboard is easier to service than an inboard. With the boat on a trailer you can simply stand next to the outboard. Servicing the inboard requires working under an engine hatch, often in pretty cramped confines.
Are inboard or outboard motors safer?
Inboard boats are the safest style of boat for pulling a rider, but if you do plan to pull a rider with an outboard or inboard/outboard boat then all of the same safety tips for wakeboarding with an inboard boat will apply, plus some extra precautions.
How long do inboard engines last?
An inboard engine can run for an average of between 1500 to 2000 hours depending on the type. As with outboard engines, maintenance is crucial to prolonging the usefulness of an inboard motor. Ventilation is crucial for an inboard motor and should be continuously checked; otherwise overheating could cause a fire.
Do you drive a boat or con it?
What is the word for driving a boat? The generally accepted phrase is conning the boat. Although for smaller craft terms such as steering, piloting.
Is driving a boat hard?
Driving a boat is more complicated than driving a car, so it’s not surprising that you’re nervous about your trip. But it sounds like your friend has quite a bit of experience driving a boat (he or she is a boat owner after all), so you should have guidance to help you along the way.
Can you leave a stern drive boat in the water?
Never leave the sterndrive trimmed up in the water for an extended period of time. In this position, marine growth on the stainless ram can damage the seals to the ram cylinder.
