Experts say that the life expectancy of a boat engine depends on several factors. There is no set number since different makes and models of outboard motors differ in quality, maintenance procedures, and frequency of use.
We cannot determine the exact lifespan of an outboard motor, but you can come closer to an approximate figure by looking at a few factors. In this blog, we’ll explore those factors and help you figure out the life expectancy of your outboard motor.
What are the Ideal Hours for an Outboard Motor?
Most experts say you can expect to get 1,500 hours out of a gas boat engine before it needs to be rebuilt. This means you can drive at cruising speed every day, and still only use up one year’s worth of driving time in ten years. Your boat motor is likely to have fewer than this if it has been taken care of.
If you have kept up with the service schedule, and your boat has between 500-1,000 hours, you probably won’t need to replace the engine for at least the next 5 to 7 years, depending on how often you use it.
In most cases, they start to run rough and begin showing signs of wear and tear. But it’s not always the case since other factors, such as maintenance, weather conditions, and frequency of use, come into play. The number of hours on an outboard motor can be misleading if the owner has not maintained it well.
A boat engine that has been taken care of regularly may have fewer issues than one with only 500 hours under its belt. On the other hand, if you have bought used boats for sale, you might need to keep an eye on the hours you drive than when you buy new boats.
The short answer is there are no rules set in stone for how many hours are too many for an outboard motor. It all depends on how well it was taken care of. But certain guidelines help determine the condition of an outboard motor.
4 Factors That Influence the Life of an Outdoor Motor
There’s no single answer to how many hours on a boat motor are too many. This depends on how well you maintain your boat, what kind of engine you have and how hard you run it, along with a few other factors like:
Quality of the Fuel Used
The quality of fuel can have a huge impact on how long an outboard motor will last. Fuel that is contaminated with water or is stale will cause corrosion and even rust on the engine’s internal components and you can detect it if there’s white smoke. Also, lower-quality fuels can result in carbon buildup, which can clog up your engine and result in costly repairs.
You need to use high-quality fuel to ensure proper combustion and prevent corrosion inside the cylinders and pistons.
How often you have your boat serviced will significantly impact how long your boat engine will last. It’s advisable to adhere to the manufacturer’s recommendations when it comes to maintenance.
Regular maintenance includes changing spark plugs, oil filters and oil changes, etc. and it’s vital to give more importance to maintenance schedules during the winter season.
The intervals at which these maintenance tasks need to be performed vary based on the make and model of your boat engine. As long as you follow the recommended schedule, this will help maximize the life expectancy of your boat engine.
You may also want to conduct regular inspections between service intervals, primarily if you use your boat frequently.
Frequency of Use
How often do you use your boat?
If you only use it occasionally, say once a month during the summer months, your boat engine won’t get too much wear and tear. However, if you use it every weekend and attend boating events regularly, then it’s more likely that some parts may need replacing more quickly.
The Make and Model of Boat Engine
Some boat manufacturers use higher quality parts, which results in better performance, a high horsepower and a longer life span. Also, the technology used by some brands is superior to others, meaning it’s easier on your engine and helps extend its life span.
For example, the Yamaha Outboards has a four-stroke engine with high volumetric capacity and driving efficiency with high-quality parts. This means that Yamaha Outboards and other similar brands have better performance and can improve the boat life.
How Can You Find Out If Your Outboard Motor has Too Many Hours?
When buying a used outboard motor, it’s essential to know how many hours are on the engine. You want to make sure that your choice has a lot of life left in it. But how can you tell if an outboard motor has too many hours? Here’s what to look for.
- The first sign that an outboard motor may have lived past its prime is its appearance.
- If you see corrosion or rust, it’s a good indication that the motor hasn’t been cared for properly and might have too many hours.
- Other signs include oil leaks and fuel leaks.
- Scrutinize the exterior of the motor before making a purchase.
- You should also run a compression test on an outboard motor before buying it.
- Compression power indicates how much energy the engine can generate during this process, so if your test shows low compression power, there might be something wrong with your engine.
An outboard motor can last for many years even when you’re using it regularly — with a few precautions and routine maintenance. So if you’re thinking about investing in an outboard motor or looking for servicing options, you can reach out to our Yamaha outboards dealers today to get more details.
