There are several types of outboard motors that vary in size and power source. Large outboard motors can generate over 500 horsepower and are suitable for large boats, while portable motors are small and lightweight for powering small watercraft. An outboard motor consists of three main sections - the powerhead which houses the engine, the midsection which attaches the motor to the boat, and the lower unit which contains the propeller and gearbox. Common parts that often need replacing due to wear and tear include components in the lower unit like the propeller as well as the carburetor and fuel pump in the powerhead. When repairing or replacing parts, it's important to use genuine manufacturer parts and diagrams to ensure compatibility

There are steps in understanding what you need:
We provide the reliable and high quality boat repair parts with discount price and
great customer satisfaction.
1. Always research on outboard motors manufacturers. If you own a Mercury
Outboard, you need Mercury parts or an OMC needs OMC parts and so on.
Even though this step seems quite obvious, you will surprised to learn that
many end up buying mix and match parts or even aftermarket parts as it’s
a cheaper alternative. The saying “pay now or pay later” holds true in this
regard, as you don’t want to regret not getting the correct OEM parts when
you’re at sea or cruising lakes with your family and friends.
2.The next step entails knowing which year and model your outboard is. You also
need to know what component you need to fix i.e. lower unit, fuel pump
etc.
3.It’s always useful to use a diagram to find the specific parts that you need for
your repairs. Always remember to buy the nuts and bolts as well. Try

Various types of motors:
Large Motors: Large outboard motors are usually for boats 37 feet or longer and
are motors that have powerful V6 and V8 cylinder blocks that are rated up to 557
horsepower. The large outboard motors are usually bolted or bracket bolted to
the transom and have controls that are linked to the helm. There are also large
outboard motors that have two to four cylinders that can generate 15 to 135
horsepower that are suitable for hulls up to 17 feet.
Portable Motors: Portable outboard motors are relatively small and go up to

2. about 15 horsepower. Camps are used to affix and remove the motor from the
boat. Portable outboard motors are usually started by a manual pull cord hand
have both the throttle and gearshift controls on the side of the motor. A tiller is
used for steering and the motors are usually used to power small craft, provide
auxiliary power for sailboats, and provide small craft the ability to troll along with
other larger craft.
Electric-Powered Motors: These are also known as trolling motors, and are
usually only used on small craft or when gasoline-powered motors are not
allowed. They are much quieter and cause zero emissions.
Pump-Jet: This type of motor is a marine system that creates a jet of water for
propulsion. The pump-jet engine has an intake that allows water to pass below
the vessel into the engines. Water enters the pump through an inlet.
Parts of an Outboard Motor
There are three major sections of an outboard motor which are the powerhead,
the midsection and the lower unit. The midsection includes the exhaust housing,
the lower unit includes the gearbox and has the anti-ventilation plate, water
intake propeller and skeg.
Powerhead: The powerhead includes the engine which is usually not put in the
water. To start an outboard motor, a person must use a pull cord which provides
the spark that gets the cylinders firing on the downward stroke. Most engines are
cooled by water. Parts included in the powerhead include the fuel tank, a speed
control lever, the carburetor, and the reed valves.
Midsection: The midsection includes the mounting bracket and the exhaust
housing. The bracket is used to attach the motor to the boat and the exhaust
housing removes the used elements from the engine.
Lower Unit: The lower unit includes the propeller that provides the bats
propulsion. The propeller can be tilted so that it does not hit the bottom in more
shallow waters. The skeg is the sternward extension of the keel that has a rudder
mount under the center line. The propeller is usually made of aluminum but
there are also stainless steel propellers that are stronger then aluminum. The
lower unit is one of the most commonly damaged part of a boat motor. Often
times trees and rocks lurk under the water where they cannot be seen and once
the motor hits the obstruction, damage to the lower unit results. There are several
affordably priced options to replacing your lower unit. Find a shop with options
and one that is willing to work with your insurance and don't always choose the
lower priced guy. Look for knowledgeable and helpful staff who will give you
honest answers, not just the answer you want to hear to get the sale.

3. Undertaking your own engine repairs is a great way to feel accomplished and
become a proud boat owner. Many even see it as a relaxing past time. Always
ensure you understand all the concepts, parts and procedures regarding boat
repairs before beginning your project.
