What does sterndrive mean?

What is the difference between sterndrive and inboard?

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. Since a sterndrive boat has the equipment on the back of the boat, it allows more room onboard than an inboard boat.

Is sterndrive better than outboard?

Sterndrives cost more to maintain, but they offer more access to the rear of the boat. On the other hand, outboards are slightly cheaper to maintain. They also offer better economy due to being a lighter package, and have more space inside the boat.

How does a stern drive work?

A stern-drive engine is attached through the transom to a drive unit (also called an "outdrive") that is essentially the lower unit of an outboard. The engine turns a drive shaft that is attached to a propeller at the other end.

Is a stern drive an outboard?

Sterndrive engines, also known as inboard/outboards (I/O), are a combination of inboard and outboard engines, as their name suggests. In sterndrive engines, the motor is in the back of the boat under the transom. The drive unit is tucked beneath the swim deck.

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.

Why are boats going to outboards?

Compared with all three other propulsion systems that basically have an engine in the boat, using multiple outboards makes the boat faster because of a beneficial power-to-weight ratio and, in most cases, the outboards are more fuel-efficient.

What is the advantage of stern drive?

Advantages of the sterndrive system versus outboards include higher available horsepower per engine and a clean transom with no cutouts for the outboard installation and no protruding powerhead, which makes for easier ingress and egress for pleasure boat passengers, easier fishing and easier retrieval in rescue …

Why do boats in Florida have outboard motors?

Outboard motors are easy to maintain when compared to inboard motors because of their positioning. They also maximize the usable space inside the boat.

What’s more reliable inboard or outboard?

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. Keep in mind that inboard motors also require better insurance.

Can you surf behind a sterndrive?

What is this? To recap, you should ONLY wakesurf behind an inboard board, never behind an outboard or inboard/outboard (stern drive) due to the risk of making contact with the propeller and the proximity of the exhaust.

Are outboards better for salt water?

Outboard Motor: What’s Right For You? Inboard engine boats are better suited for performing water sports. 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 more fuel efficient inboard or outboard?

Inboard Diesel Sterndrive has Greater Fuel Efficiency With both boats running at 25 knots, the outboard-powered petrol boat burned 15.8 gallons (60 litres) of fuel per hour. In comparison, the inboard sterndrive-equipped boat burned through only 10.6 gallons (40L) per hour.

Are outboards faster than Inboards?

Inboards on average can run 1,500 hours before tune-ups, while the outboard counterparts typically run 750 hours before service is needed. But buying the inboard motor will cost you more upfront and can require more expensive insurance coverage.

Is 1000 hours alot for a boat?

Recreational boats are used between 75 and 150 hours per year. Using 100 hours as an average, a ten-year-old boat with 1000 hours on the engines should have plenty of life left in it.

What is considered a lot of hours on a boat?

There are a few things to consider when looking at boat hours. Unless you are looking at a really high hour boat (2,000+ hours) there are typically very few drawbacks to the number of hours a boat has. In fact, a boat with normal hours (50-75 per year) will often time run better than a boat with low hours.

Which is better 2 or 4 stroke outboard?

4-Stroke Outboards Pros The fuel efficiency of a 4-stroke motor can be 50% better than that of a 2-stroke motor with the same HP. As for environmental concerns, 4 stroke outboards produce far less harmful emissions, which can be as much as 90% cleaner than those from a similar sized 2-stroke motor.

Why do boats have 2 engines?

With two engines, your boat is producing a lot more torque and the result is better time to plane, especially with the boat fully loaded. Top end performance is a result of horsepower. With a total of 600hp vs 430hp, the boat is going to go faster with more horsepower.

Why would a boat need 4 outboard motors?

Unlike all-out speed, hole shot can improve significantly when you add a fourth outboard to the same boat. This is because you have more power and greater propeller blade area in the water for increased thrust. At the same time, drag is less of a factor as the boat is accelerating from a standing start.

Is Mercruiser a good engine?

The main reason boaters select Mercruiser is the engine’s reliability. Using an engine you can count on throughout your ownership is a big perk. Boaters also appreciate the Mercruiser’s fuel efficiency and performance.

Which is better Mercruiser vs Volvo Penta?

If you’re looking for the best quality, high-maintenance, and a premium level inboard, go for Volvo Penta. But it’ll cost you more. If you’re looking for a mid-range budget inboard, Mercruiser is the right choice for you. It is also a good quality sterndrive.

What is a Mercruiser sterndrive?

MerCruiser Sterndrive or Inboard-Outboard Engines (IOs) A MerCruiser sterndrive is essentially a car or truck style engine mounted inside the boat, lower in the hull. The engine is then connected through the transom, or back of the boat, to an outdrive unit that hangs down below the boat’s bottom.

Can you start an inboard boat motor out of the water?

Are two outboards faster than one?

All things being equal, including horsepower and weight of the hull, a single outboard should come out ahead when it comes to speed, because a single gear case and propeller create less drag in the water than two. In addition, the weight of two smaller outboards usually exceeds the weight of one large motor.

Can you wake surf on a regular boat?

You cannot (and should not) wakesurf behind any boat. The nature of the sport of wakesurfing determines what boat can be used safely. The surfer has to be sufficiently close to the boat (as little as 10 feet), unlike wakeboarding in which the surfer can be much further away (as much as 60-90 feet).

What is the difference between an outboard and a stern drive?

Outboards provide more room in the boat because they are installed on the transom, outside the boat. A sterndrive 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.
