Similarly how long do outboard engines last. Two-stroke outboard motors can reasonably live between 1500 to 2000 hours before needing major maintenance and 4 stroke engines can last longer.
Lets break down what each does to the longevity of a motor so you can know how long yours has or which motor you want for future reference.
How long will an outboard motor last. Lets break down what each does to the longevity of a motor so you can know how long yours has or which motor you want for future reference. On average an outboard motor will run about 1500 hours or 7 to 8 years. Each outboard motor will be different but if you keep up maintenance and take care of the motor it can last much longer.
A typical estimate from the industry is that an outboards motor last around 1500 hours of operation. Assuming the average owner uses their boat 200 hours a year this would mean that the motor would last between seven and eight years. It seems many have an opinion on how long an outboard lasts and for every one answer there are many others who can cite instances to the contrary.
Some believe that a motor should get between 1000 and 1500 hours of life and some cite 20 to 30 years of service. You can expect your outboard motor from Mercury Marine to last you around 2000 to 3000 miles or longer with proper maintenance. Conclusion Life expectancy of an outboard motor really is dependent on how well you care for it.
Two-stroke outboard motors can reasonably live between 1500 to 2000 hours before needing major maintenance and 4 stroke engines can last longer. All engines will last even better with proper maintenance and preventative measures. Outboard motors are depending on the water cooling and like any car motor which overheats will be destroyed in a very little amount of time.
People tend to run their boats where they think there is water but they are putting their motor in the mud sand logs etc and destroying it that way. Car engines running down the highway at less than half throttle most of the time can go for 150 - 200000 miles easyat an average speed of say 50 mphthat translates to 4000 hrs. Id be really surprised and happy if an outboard engine could make it to half that many hours of use before need for major overhaul or disposal.
Will the average outboard wear out due to wear and tear of the internal components or will it basically corrode away. Or does reliability become the main issue and the electrics just dont work any more. Is a modern four stroke with its incredible complexity going to last as long as a two stroke which is a much simpler motor.
Part of that routine is the so-called fogging of outboard engines which is the process of injecting oil into the carburetor and cylinders so that the engine wont rust during storage particularly if it is subject to wide temperature changes causing internal condensation. My question is just how long is this storage technique good for. The electric outboard motor runtime and range depend on how fast you run it how heavy the boat is how much tide is running in which direction the battery charge state the temperature and more factors still.
Generally speaking with the Spirit 10 Plus 3 hp electric outboard at half power you should get 16 miles. Similarly how long do outboard engines last. About 1500 hours Also question is how many hours will a 50 Mercruiser last.
If you do you should get more than 4-5 years unless youre boating in the saltiest of waters. Oct 3 2009. I have a 99 Evinrude 150 FICHT that was winterized professionally in MASS.
The boat sat for 3 years OUTSIDE and finally I have got time to use it again. Brought it to a marina to have them fire it up and they told me the engine is no good. The engine was running perfect when it was winterized.
The general feeling in the marine industry is that an outboard engine will last for about 1500 hours of operation. Given about 200 hours of use a year this would be about 7 or 8 years but Johnson outboard motors can achieve regular oil changes say every 50 hours and maintenance and a rebuild or two 10 15 or even 20 years. There is huge difference in cruising an outboard engine at 4000rpm vs 2200 rpm.
The other major item is exterior corrosion especially on key components. If an engine is kept like new on its exterior well lubed corrosion free etc it will last a lot longer before needing expensive non powerhead repairs. Exterior condition also tells the tale.
How long do outboard engines last. Why do boats go to one side at rest. If your boat lists at rest there is too much weight on one side.
It could be gear or it could be water trapped in a stringer bay. When you look at the shelf life of the typical impeller it is typically listed as 10-15 years. How long the impeller will last if it has been manufactured and sits out its life on the shelf.
So the life in your motor will be less than that. If that is done it is not unrealistic to expect the gasolineoil mix to stay useful for up to one year. Fogging is for coating the interior engine parts with additional oil.
A few years ago Suzuki actually did a study to see how long an impeller would last if you started the motor dry said Greenwood and it was about 20 or 30 seconds Jansen showed me a Mercury outboard water pump housing he removed this season that is coated with melted rubber see photo 2 above. Keep it at bay and a modern outboard motor should keep cranking for thousands of hours of operation. And when it comes to boats as Capt.
Thiel contended some years ago thats pretty close to forever. Before storing your boat car or any engine for an extended period of time its a good idea to prep it in some way. You can consider turning the engine over.
With regular maintenance the proper kit for your Yamaha or Mercury model and the right set of tools most outboard issues are fully preventable. Still there are a few specific ways to keep your outboard motors fuel system in top shape. Another option for supporting the longevity of your motor is fuel stabilizers.
So with a significant number of caveats well say that it is typical for a well-maintained Mercury outboard to last for about 3000 4000 hours of operation. But as stated there are so many factors influencing engine life. Mercury outboards are extremely well-engineered engines and we have seen many with 6000 and even 12000 hours on them still.
