Any avid boater knows that the maximum speed of their vessel will be dependent on several factors. The size of the boat, the engine, the type of hull and load conditions can all have an impact on your speed. In this article, we will take a closer look at why your boat may only be reaching 15mph and what factors could be influencing your speed.
Why will my boat only go 15mph?
First of all, it is important to understand the different components of your boat that contribute to its speed. The hull shape and size of your boat can be a major factor. It is well known that a flat bottom boat, which is more common in drift boats and pontoon boats, will perform worse in terms of speed compared to a V-shaped hull that is traditionally seen in speedboats, fishing boats, and water-ski boats. Therefore, if you are looking to increase your boats speed, it might be worth looking at different shapes of hull.
Apart from hull design, your engine can also play a major role. If your engine is not powerful enough, the boat won’t be able to reach its planned speed. Look for an engine that is suitable for the size of the boat, that has enough power to reach a higher speed. It might also be worth doing some research into the differences between 2-stroke and 4-stroke engines, as these will have an impact on the speed you can reach.
Load can also be an important factor. If you are going out on the water with too many people in the boat, or carrying objects and equipment that are too heavy, the boat will struggle to reach its maximum speed. Therefore it is important to make sure there is a balanced base weight in your boat, and carefully calculated the total weight of your passengers and cargo before setting off to avoid weighing down your boat.
Finally, weather conditions can be a factor that affects the speed of your boat. If you are out in a stormy or choppy seas, your boat is more likely to struggle to reach a top speed. It might be worth paying attention to the forecast when you go out, and plan accordingly.
What to do if your boat engine dies?
If your boat engine dies, the first thing you should do is remain calm and assess the situation. Take your boat to a safe and stable place and ensure that everyone on board is out of danger. Check for any obvious problems such as a loose fuel line or an empty fuel tank. If the engine is on fire, use a fire extinguisher if you have one aboard. If the fire cannot be extinguished with a fire extinguisher, immediately call for help from nearby boaters or the coastguard. If the engine is simply dead, it could be a problem with the fuel, electrical system, or other component. Try to troubleshoot the issue, but if you are unable, it is best to refer to the boat’s manual or contact a marine mechanic. If you are stranded in the middle of the ocean, it is important to be alert and stay afloat until help arrives. Always carry safety equipment with you, such as a life jacket, signaling device, and flares. Together with following advice from the coastguard or other boaters, this will help ensure your safety.
How can I get more speed out of my outboard?
There are several ways to increase the speed out of your outboard engine. Firstly, you should check the engine’s spark plug. If it is worn or appears to be dirty or corroded, then replace it. Secondly, you can check and if necessary replace the propeller, as a worn propeller can drastically reduce speed. Additionally, the fuel you are using might not be of the highest quality, which can lower the speed of your engine – so consider switching to a better brand. Lastly, make sure the trim of the motor is set correctly, as too much trim can create drag and slow down the boat speed.
How can I get more speed out of my outboard?
- Make sure that your outboard motor is properly serviced and maintained. Change oils and lubricants regularly and check for any concerns with the motor or the propeller.
- Ensure that the propeller pitch is appropriate for your needs. A larger diameter propeller can help to increase speed by allowing more water to be displaced.
- Make sure that the engine is not over-propped. If it is running too fast, it can actually reduce speed.
- The weight of the boat affects speed as well. If the boat is carrying too much weight, this can slow it down. Try to reduce weight where possible.
- Clean and polish the hull of the boat regularly. This helps to reduce drag and improves the overall efficiency of the boat.
- Use high-octane petrol. This helps to increase the overall power output of the engine.
- Reduce any engine drag – clean or replace the water pump impeller, adjust the carburetor and replace any worn parts.
- Ensure that the fuel line is not clogged up with dirt, oil, and other debris.
- Increase the revs of the outboard motor. This increases the speed of the boat up to a certain point.
- Adjust the trim of the motor to find the best angle for the propeller. This can help to increase the speed of the boat.

Why will my boat only go 15mph? – Conclusion
In conclusion, there could be a few different reasons as to why your boat will only go 15mph. The most common reason is that the maximum speed of a boat is typically around 15mph. This is because boats are designed not to go faster than this as a safety precaution. Additionally, the motor of the boat might need to be serviced, as this could be limiting its power and resulting in it not being able to reach top speed. Fuel type and quality could also be an issue, as boats require special high octane petrol to be able to reach top speed. Finally, the size and shape of the boat could also be a factor – smaller boats with sharp hull shapes tend to be faster and will more easily reach higher speeds.
