Outboard Motors Experiences

On 4 stroke outboard engines, other than checking your oil level at regular intervals, changing the oil is the next most important task. Regular oil changes will prolong the outboards life. You can do this task yourself without too much trouble. Here are the steps you need to take to change your outboard motor’s oil.

The Japanese seized on this fact and gradually Honda, Yamaha, Suzuki and Tohatsu concentrating on small outboards began to take over as market leaders. They achieved this domination by improving efficiency and reliability. As well as adding features to these small outboards previously only found on larger engines.

Having achieved success in the small outboard market, these Japanese manufacturers expanded up the power range. They again came to dominate the outboard engine market up to at least 20 hp. Now the Chinese have entered the market. Basically doing what the Japanese did previously, copying the best features of the present engines and at the same time keeping costs down.
