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.

Are stern drives reliable?

The biggest down-sides to having a stern drive usually boil down to reliability, and maintenance costs. Due to the additional moving parts there are more potential failure points than there are on either outboard or inboard boats.

Which is better sterndrive or inboard?

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.

How long will a stern drive 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.

Is sterndrive the same as inboard outboard?

Is sterndrive better than outboard?

Not many people talk about that, but it just shows the technology in the sterndrive market.” Technology has also improved corrosion protection – especially in the saltwater environment – for sterndrives.

What is the difference between sterndrive and V drive?

Sterndrives (or outdrives) have long proven popular, as they are incredibly versatile and keep a clean, obstruction-free transom. V-Drives are a twist on the traditional “ski boat” inboard, and boast a hardcore wake sports heritage without the cockpit-clogging mid-engine.

How does a stern drive work on a boat?

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.

How much HP can AV drive handle?

V-drives can certainly handle the power, 2000 hp or more (used in top fuel drag boats), and the drives system parts cost less than a Bravo XR. Speed capability is not a problem. They run them to up to 260 mph.

What is a Walter V-drive?

Walter V-Drives are precision gear drives which allow inboard engines to be placed in the stern (rear) of a boat. Advantages include: Greater safety (with propeller tucked under the boat, not under swim platform) Improved handling, reduced drag and bow rise. Shallower draft.

Will a 4.3 MerCruiser pull a skier?

My cousin had a 19' Searay with a 4.3 in it, and it pulled great! We got 4 skiers up at one time. It was hard, but we did it! 2 of us were 200+ lbs at the time, too.
