Outboard motors for a boat are developed as a self-contained unit with engine, subsidiary systems, and propeller, designed to be mounted at the stern (rear) of the craft. They are the most common motorized method of propelling small watercraft.
As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the orientation of the propeller. The transmission leg in the water also acts as a rudder even when the propeller is not providing power.
Before you buy an outboard engine you need to think about a few things such as the hull's weight. This is because once you know the hull's weight you can get the right engine as you don't want an under powered or over powered engine that will cause you problems.
An outboard motor can be an expensive purhase so take your time to do research by reading reviews and looking at different shops.
