Choosing the engine (or propulsion system) for your

boat is very important. Both the weight and the

horsepower will have a major impact on the performance

of your boat. If you have a boat that's underpowered,

the engine will work twice as hard, giving you poor

performance.

Now, we will take a look at the motors available

for boats and vessels:

Outboard motor

An outboard motor is very popular and very useful on

small boats. These motors are very light, powerful,

and extremely quiet. Normally mounted on the transom

of a boat, there are boats available that offer a

motor well or even a bracket to mount the motor to.

The entire motor will swivel about, providing easy

steering as the turning propeller pushes the stern

about. Outboard motors come in many different sizes

and the horsepower can use different types of fuel.

Stern drive

These motors are also known as I/O engines, and

normally heavier than outboard motors. Consisting

of an engine mounted inboard and a lower unit

attached to the transom, these motors offer power

and versitility. You can also tilt the motor up

and down to help provide boat trim while you cruise.

Inboards

On boats that are over 26 feet in length, these

motors are very popular. Similiar to the stern drive

motor, the inboard motor is mounted inside the boat

towards the center, giving you good weight proportion.

Inboards connect directly to the transmission, then

on through the hull of the boat. Then, the shaft

is attached to a propeller which will turn and

propel the boat. The shaft is fixed and doesn't

swivel around. Therefore, a rudder is mounted

behind the shaft and propeller to help deflect the

flow of water which provides your steering direction.

Jet drive

Jet drive propulsion systems have a big advantage -

no propeller to cause damage or injury to those in

the water, including marine life. Normally, they

are inboard engines that will take in water that

flows through a pump, powered by an impeller.

Then, the water is discharged at a very high pressure

through a nozzle that will propel the boat. To

provide steering for the boat, the nozzle will

swivel. For personal watercraft, a jet drive is

the way to go.

Keep in mind that when power isn't being applied,

jet driven boats will lose steering, as the stream

of water that propels the boat won't be there.

Therefore, always keep any part of your body away

from the pump intake - and never operate these types

of boats in shallow water.

The landscape of search engines have went through

some drastic changes over the years. Not only with

technology, but also with various partnerships

between the many different search companies as well.

In relations to marketing, search engines can

provide anything you want to know. If someone is

search engines. When they type it in, the highest

sites on the engines will show - which is normally

In today’s net-savvy world it has become common for any business to have a website which they use mostly for advertising their products and services. With the advent of search engines it has become even easier for the customers to search for the stuff online. For a website to be successful its link should land in the first three pages which the search engine brings and the rank of the page should be high which means many visitors come to the site. This can be achieved by applying search engine optimization or popularly known as SEO. This is a marketing strategy which increases the quality and quantity of traffic flow to a particular website via search engines.

SEO not only affects the search engine results, but also image search, video search and industry specific vertical search engines. It determines how a search algorithm functions and searches what is popular with people. When a website link is submitted to a search engine, a spider crawls through a page to gather links which lead to other pages and stores those pages on the server of the search engine. The information collected from these pages is sent to the indexer, whose job is to extract information from those pages such as the keywords and their weights, the location of the page and other links that are stored for the spider to crawl in future.

In the beginning, the search engine optimizer algorithms were dependant on the keywords, Meta tags, and index files provided by the Webmaster. Meta tags provided information about a particular page, but using them for indexing the pages didn’t prove to be successful as some Webmasters added irrelevant Meta tags to increase the number of hits and earn huge ad revenue. They even changed the HTML of the web pages to achieve a good rank for the page. But this was a case of abuse as it fetched irrelevant pages.

Search engines then began utilizing complex ranking algorithm, which were difficult for the webmasters to manipulate so as to provide web surfers with genuine results. The rank of the web page was calculated mathematically by functions using strength and quantity of the inbound links. The higher the rank of the page the more chances it had to be viewed by a person. Later algorithms were developed which considered various other on-page factors such as rank and off-page factors such as hyperlink. Since the webmasters couldn’t manipulate the page rank, they began exchanging, selling and buying links, which lead to link spamming and even creation of numerous sites dedicated for this purpose.

Algorithms became more complex by every passing day and top search engines kept their algorithms a secret. As the cost of SEO increased, advertisers were roped in to pay for it, which finally resulted in high quality web pages. Although investing in SEO is very fruitful, but at the same time is risky because with out any prior notice the algorithms being used are bound to change and the search engine will stop directing visitors to the page. Many consultants are available in the market that provides SEO services. They manipulate the HTML source code of the web site like menus, shopping carts and sometimes even the content of the website to draw more traffic. Search engines like Yahoo has algorithms that extract pages not according to the page rank but according to the cost per click or set fee, that is if a advertiser desires that the page containing his ad be displayed, he is expected to pay money for it. This is a point of controversy, as only the big businesses will be able to increase the number of hits of their page but not the small business who might be having a better quality page.

Google Ad Words explores ads which have words typed in the search box by the surfer. The Million Dollar Homepage started the concept of Pixel advertising, which is a graphical kind of advertising. Depending on the pixels, the space is sold to the advertiser. Keyword advertising involves advertisers who buy URLs of a site and place their ads at that location. Thus SEO is a market in its own which is yielding great results for businesses on Internet.
