Marine Motors and Outboard Motors Engine Care Products

Marine fuel system additives for sale NZ

Your marine motor is an important investment, and it's important to keep it running in top condition. One of the best ways to do this is to use the right engine care products. There are a variety of products available, each with its own purpose. One of the main overlooked areas of outboard motor and marine maintenance is the boats petrol tank and fuel system. The petrol tank is a vital part of any engine, and it's important to keep it clean to ensure that the engine runs smoothly and efficiently. Over time, dirt, debris, and other contaminants can build up in the tank, which can clog fuel lines and filters, leading to poor performance and even engine damage.

To prevent these problems, it's important to use fuel additives. Fuel additives help to keep the tank clean, prevent condensation, and protect the fuel from going bad. They also help to improve fuel economy and performance. 

Fuel System Additives: Fuel system additives help to keep your fuel system clean and prevent the buildup of deposits. This can help to improve fuel economy, performance, and prevent engine problems.

Fuel Stabilizer: Fuel stabilizer helps to prevent fuel from going bad. This is important if you store your boat for long periods of time. Fuel stabilizer will help to keep the fuel fresh and prevent it from gumming up your engine.

Fuel Conditioner: Fuel conditioner helps to improve the lubricity of fuel. This can help to protect your engine from wear and tear. Fuel conditioner can also help to prevent fuel from foaming, which can cause problems with your engine.

Petrol Tank Condensation: How to Prevent Water in Your Boat's Fuel System

Water in outboard petrol causes breakdownWater in your boat's fuel system is a major cause of outboard motor breakdowns and marine engine running problems. Water in petrol is usually caused by condensation, which can occur when the temperature of the air inside the tank drops below the dew point. This can happen when the boat is stored in a cold environment, or when the tank is filled with warm fuel and then exposed to cold air.

The Risks of Condensation

Condensation in a petrol tank can lead to the growth of bacteria and other microorganisms, which can contaminate the fuel. This can cause the fuel to go bad and eventually clog the engine. In addition, water in the fuel can also cause the engine to run rough and inefficiently, and can even lead to premature engine failure.

How to Prevent Condensation

There are a few simple things you can do to help prevent condensation in your boat's petrol tank:

  • Fill the tank up as full as possible. This will help to minimize the amount of air in the tank, which can cause condensation.
  • Use a fuel stabilizer. A fuel stabilizer will help to keep the fuel fresh and prevent it from going bad.
  • Run the engine regularly. This will help to circulate the fuel and prevent condensation from forming.

Conclusion: By following these simple tips, you can help to prevent condensation in your boat's petrol tank and keep your engine running smoothly.


Carbon Buildup: The Importance of Carbon Guard for Marine Engines

Outboard motor carbon buildup - damaged engine

Carbon buildup is a common problem in marine engines, and it can lead to a number of problems, including poor performance, decreased fuel economy, and even engine damage. Carbon guard is a fuel additive that helps to protect your engine from carbon buildup. It works by dissolving and dispersing carbon deposits, which can build up in the engine's combustion chamber, intake valves, and other areas. Carbon guard helps to keep these deposits from building up, which can help to improve engine performance and fuel economy.

There are a number of benefits to using carbon guard, including:

  • Improved engine performance
  • Increased fuel economy
  • Reduced emissions
  • Longer engine life
  • Protection from carbon buildup

Carbon guard is easy to use. Simply add it to your fuel tank according to the instructions on the bottle. You can use carbon guard in both 2-cycle and 4-cycle marine engines.

If you're looking for a way to improve your engine's performance, fuel economy, and longevity, carbon guard is a great option.
