A sterndrive is a marine propulsion system that is attached to a sterndrive, also known as an outdrive. The drive unit is both the transmission and propulsion. 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.
What is better sterndrive or outboard?
If you want a transom for water play, the smart move is to get the sterndrive. If you want better corrosion resistance and easier maintenance, plus drives that can be trimmed clear of the water, go for the outboards. It’s your call, and with the Aviara AV32, either choice is a winner.
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.
How does a boat sterndrive 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 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.
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.
Is an inboard or outboard better?
Outboards are designed specifically for boating. Inboard/outboards are just “marinized” automobile engines stuck in a boat. Outboards provide more room in the boat because they are installed on the transom, outside the boat. Four-stroke outboards offer much better fuel economy, less GPH, more MPG than I/O motors.
What is better outboard or inboard outboard?
Inboard vs. Because it will usually weigh less and be a more-efficient design, an outboard motor will typically deliver better fuel economy than a sterndrive. However, most sterndrives can not be tilted completely out of the water, while most outboards can clear the water when tilted all the way up.
What is the difference between sterndrive and V-drive?
Ultimately, V-drive systems offer more space amidships than a conventional inboard and require less maintenance and service than sterndrive systems. While sterndrives are faster and more fuel-efficient, a V-drive can swing a bigger wheel, and you’re more likely to find a replacement prop when far from home.
Are Mercruisers reliable?
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.
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.
Can you beach a stern drive boat?
If you just beach your boat stern out, it does not take much wave action or tide change to leave you stuck and in a real mess.
Do motorboats have gears?
Boat engines don’t have transmissions because they add a lot of undesired complexity for a minimal speed gain. Usually, the propeller doesn’t turn at speed equal to its engine; if it does, it cavitates & reduces its life span. Adding gears increases speed, which increases cavitation, so no gears.
Do Sterndrives have transmissions?
A sterndrive is a marine propulsion system that is attached to a sterndrive, also known as an outdrive. The drive unit is both the transmission and propulsion. When the captain turns the steering wheel, the entire drive turns. No rudder is needed.
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 the difference between inboard and I O?
A true inboard is fully inside a boat and an I/O has components within and outside of the boat. A true inboard is less common. True inboard motors will be found on boats designed for skiing as they produce less wake and drive much smoother.
What are the four length classes of vessels?
Let’s review the four different classes of recreational boats as determined by length. Class A. Boats measuring less than 16 feet. Class 1. Boats measuring more than 16 feet but less than 26 feet. Class 2. Boats measuring more than 26 feet but less than 40 feet.
What year did boats start using catalytic converters?
companies start installing them with their 2010 engine models. is how the change over occurred in California in 2008 and it seemed to work fairly smoothly. If there was ever a reason to buy a boat before a model change over this is it.
Do inboard boats have catalytic converters?
manufacturers 4th June 2009 A senior figure at the National Marine Manufacturers’ Association (NMMA) has reiterated that all new stern drive and inboard gas engines built from next year onwards for US boats will need catalytic converters.
