Each outboard motor will be different but if you keep up maintenance and take care of the motor it can last much longer. Our 1000 hour boat serviced every 50 hours would have had the same 20 oil changes.
I was in Fiji in the 1970s.
How many hours does boat engine last. An engines weight and horsepower can impact the performance and the longevity of your motor. How Long Do Boat Motors Last. Boat motors typically last at least 2000-3000 hours before they need serious maintenance.
Inboard motors will sometimes last longer because they are more protected from wear and tear. The Life Expectancy of the Marine Engine. The average marine gasoline engine runs for 1500 hours before needing a major overhaul.
The average marine diesel engine will run for more than three times that long and log an average 5000 hours under the same conditions. 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.
Depending on our needs as anglers different outboards will be better for us. Most marine engine manufacturers recommend an oil change every 50 engine hours. Our 1000 hour boat serviced every 50 hours would have had the same 20 oil changes.
Similar levels of wear can be assumed in this example. Some newer vehicles have an engine hour meter. Here is a picture of the hour meter on one of our shop trucks.
The use of the engine and the location. For boats that live in Florida and get used regularly we would say that the average number of hours for a boat will be around 2000 hours. That is just the average number of hours that are going to be on a 5-10-year-old engine that has been used regularly throughout the years.
A gasoline-powered motor might last around 1200-1800 hours before needing a lot of work and a diesel engine might last 5000 hours before needing a lot of work. This might not seem like many hours but many boat owners might only run their boats for 50 hours a year. But I do know a few tricks that the average boater can use to make his enginesbe they gasoline or diesellast for a very long time.
Maybe even as long as the boat itself. This 1987 135-bhp Ford Lehman SP135 diesel has approximately 3671 engine hours on her and yet she still purrs like a kitten thanks to lots of TLC. If it is now or ever has been seriously overpropped deduct 1500 to 2000 hours from that realistic 3000 hours bondo mentioned.
Its has always been the OEM Bravo III props since purchased new. Small plane engines must be rebuilt in the range of 1200-1600 hours depending on make and they are usually well maintained. You can do a test diagnostic and find out some data or even pull a head.
Also you can put clean oil in it with new filter and run it several hours to see if it remains clean. If a boat is four years old then about 200 hours would be about normal. If its five years old 250 is about right and so forth.
Rindas TechMate diagnostic tool can help with determining engine hours on a used boat with electronic fuel injection. But there are exceptions to the rule. The most common question we get regarding used boats is something along these lines.
How many hours are too many hours on a boat or How long will a boat engine last. 900 hours We often get used boats in on trade that have close to 1000 hours on the engine. Quite funky but this is typical for a high hour engine with 4000-5000 hours since the last aftercooler servicing.
An aftercooler that slides out easy and looks like thisCleans up like 100 new and has a decade plus more service still in reach. An engine block that has been heated-cooled heated-cooled heated-cooled sucesfully many times Like a old MOPAR Big-Block in a metro PD carThats a seasoned block made for great builders. It wasnt the total miles that made them sought-after builders it was the seasoning of the block lent to more stability as it had more cycles.
This is about 380 hours a year. When that is compared to a lorry or van engine they will do 8356 hours in 4 to 5 years. The older diesel engines are relatively simple engines and easy to fix to compared to modern ones with turbos and electronics both which are prone to fail.
In this video we address the misconception of engine hours on a used inboard towboatFor a more in-depth reading of comparing boat hours to miles on a car. Multiply the amount of hours on your engine by 60. Use the number you come up with to estimate how many miles are on your engine.
For example 1235 hours on an engine equates to approximately 74100 miles. Engine oil-life monitors that track engine hours rather than mileage take into account idling time rpm and other factors that aren. No way never going to happen.
Most people say average engine life of a 350 57 class engine in a tow boat is between 2000-2500 hours. 700 hours on a 10-15 year old boat that is well kept is no big deal. In either case the engine experienced much more wear and tear than typical usage.
The engine run time history report a Mercury dealer can generate using their diagnostics equipment and software will include a breakdown of hours in 1000-rpm increments from idle to the engines max rpm. Theoretically a well-maintained diesel may last the life of your boat. Since the average recreational boater logs only about 200 hours per year the 8000 hour diesel would last 40 years.
Although diesels can add considerable cost to a boat they should be seriously considered because of their durability economy of operation and safety concerns. When buying a boat it is good to know how boat engine hours affect the used boat value. Always ask how many hours the engine has on it and dont forget to dr.
This leaves us with a 10 gallon reserve or an additional 12 hour of running is. So we take the range and deduct 10 or 10 miles and the fishing range for this boat is about 80 miles with 2-3 hours of trolling time. Now not too many people take their 24 boat out 80 miles but lets say you that wanted to go to the 371 or about 40 miles offshore.
With two Ford Lehman engines. They currently have 4800 hours on each of them. I have had conflicing information as to engine life.
One source says 10000 hours while another says 5000 hours. How long should a marrage last. I was in Fiji in the 1970s.
The engines were in everything. Friend told me the enginies were also everywhere in India. GPH 04 x 300 72 12072 166 GPH.
300-hp Gasoline Engine Example. GPH 050 x 300 61 15061 245 GPH. Keep in mind that these formulas apply when the engine is making peak horsepower which usually is near wide-open throttle.
Fuel consumption will be decreased at cruising speeds.
