Outboard Motor Care

how to take care of outboard boat motor

Outboard motors are essential for any boating enthusiast, allowing them to navigate the waters with ease. However, like any piece of machinery, they require regular maintenance to ensure their longevity and efficiency. Neglecting proper care can lead to expensive repairs or even a complete replacement of the motor, which is why it’s important to understand how to take care of your outboard motor.

In this article, we will cover the necessary steps to keep your outboard motor running smoothly. From checking oil levels to cleaning propellers and flushing the cooling system, get all the information you need to maintain your outboard properly.

Outboard Motor Care – General Rules

Taking proper care of your outboard motor is essential to ensure its longevity and prevent breakdowns while on the water. Some boat owners might think that preventive boat motor maintenance is too time-consuming or expensive. However, neglecting regular upkeep can lead to costly repairs in the long run.

The first crucial aspect of outboard care is checking and replacing the water pump impeller regularly. The impeller helps circulate coolant through the engine, preventing it from overheating. Without a functioning impeller, an outboard motor could quickly overheat and cause damage. A worn-out or damaged impeller should be replaced immediately to avoid further issues.

Another vital part of maintaining an outboard motor is inspecting and cleaning the fuel line regularly. Over time, debris such as dirt, rust particles, or algae builds up in the fuel line, leading to clogs that can harm your engine’s performance. Regularly examining and cleaning the fuel line, as well as flushing the engine and burning all the fuel in the carburetor will help prevent potential problems before they arise.

Gas Outboard Care

Gas outboard motors are common in recreational boats, and proper maintenance is essential for optimal performance. The following tips will help you take care of your gas outboard motor:

  1. Check the fuel: Use fresh fuel in your gas outboard motor, and avoid using old or contaminated fuel. Gasoline degrades over time, so it’s best to use fuel that is less than 30 days old. If you need to store your boat for an extended period, add a fuel stabilizer to the gas tank to prevent the fuel from breaking down.
  2. Change the oil: Regularly change the oil in your outboard to prevent corrosion and improve performance. Check your owner’s manual for the recommended oil change schedule, and make sure to use the correct type of oil.
  3. Keep the motor clean: Regularly clean the exterior of your outboard motor with mild soap and water. Use a soft brush to remove any dirt or debris from the cooling system and propeller.
  4. Inspect the propeller: Inspect the propeller for any damage or wear. A damaged propeller can cause your outboard to vibrate, which can lead to engine damage.
  5. Check the spark plugs: Checking and replacing them if they are fouled or worn out. Fouled plugs can cause your engine to run poorly or not start at all.

Tohatsu Outboard Motor Care

If you own a Tohatsu outboard, there are specific steps you can take to keep it in top condition.

Just like any other machine or vehicle, your outboard motor needs frequent checks and servicing to ensure its longevity. This includes checking oil levels, keeping spark plugs clean, and inspecting fuel lines regularly. By performing these routine checks on your Tohatsu outboard motor you’ll avoid costly repairs down the line.

Another aspect of Tohatsu outboard maintenance is replacing worn-out parts when necessary. Water pump impeller – a small but essential component responsible for circulating coolant through the engine block – requires changing every few years. A new water pump impeller will improve cooling efficiency and prevent overheating issues.

Electric Outboard Care

Electric outboard motors are becoming increasingly popular due to their environmental friendliness and ease of use. However, just like any other type of motor, they require proper care and maintenance to ensure that they function optimally.

Ensure regular oil changes. Engine oil helps lubricate the moving parts within the motor, reducing friction and prolonging its lifespan. Check the owner’s manual for recommended intervals for changing the oil.

Finally, pay attention to the flow tube – a part responsible for cooling down the motor by allowing water to enter and exit through it. Regularly check for blockages or damages which could hinder proper functioning.

ePropulsion Outboard Motor Care

In fact, if you go electric, maintenance of the outboard motor is relatively simple.

You can forget about changing the gear oils, filters, spark plugs, and greasing the drive shaft, as well as purchasing all of the necessary items, calculating the date for performing regular outboard maintenance, and paying the yearly maintenance bill. The only things you need to be concerned about are the propeller and the anode.

The check and maintenance replacement on outboard motors is a simple job that anyone can do, regardless of technical ability. Your outboard maintenance check-up procedure might look like this:

  • Examine your propeller’s blades for wear, cavitation erosion, and other damage.
  • Check for wear and tear on the pin.
  • Examine the propeller for water plants, fishing nets, or line twine.
  • If the anode on a boat motor needs to be replaced, you can do it yourself by following the simple instructions in the user’s manual.


How Often Should I Change The Spark Plugs In My Outboard Motor?

Well, the answer depends on several factors, such as the type and model of your outboard, its age and usage frequency. However, most experts recommend replacing them every 100 hours or once per year- whichever comes first.

Neglecting this simple yet essential task could lead to various issues like reduced power output, stalling or difficulty starting the engine.

Can I Use Automotive Oil In My Outboard Motor?

The short answer is no. Outboards require specific types of oil due to their unique design and function. Automotive oils are designed for cars and trucks which have different requirements than marine engines. Outboard motor oil needs to be able to withstand the harsh conditions of saltwater, high heat, and constant vibration. It also needs to provide better lubrication for the gears inside the gearbox.

Here are a few things to keep in mind:

  • Look for oils specifically labeled as “outboard motor oil” or “marine engine oil“. You can also choose between synthetic or mineral-based oils, depending on your preferences.
  • Be sure to follow the manufacturer’s recommendations for how often to change the oil. This will vary depending on factors such as usage, environment, and model.
