How much does a marine engine cost?
Outboard motors can range from $110 to nearly $90,000 depending on power, make, model, and other factors.
Who makes the MerCruiser 454?
The MerCruiser 7.4-liter MPI (7.4L MPI), is an boat engine manufactured by Mercury Marine, a American company headquartered in Fond du Lac, Wisconsin.
Can you use a marine engine in a car?
Ford, or any other marine engine that matches the manufacturers automobile specifications will fit. However there are several marine engines made just for motor boats and cannot be interchanged. But usually if you can get the motor mounts at a auto parts store, it will fit in a car.
How much does it cost to rebuild a marine engine?
Rebuilding your engine will cost around $2,500. That difference of $1,000 to $2,000 will buy a lot of gas, so consider carefully. The same-size engine in a newer four-stroke or DFI two-stroke model will add at least a $1,500 premium, so those 90 to 115 horsepower models could now run upward of $6,000.
How many years does a boat engine last?
The average marine gasoline engine runs for 1,500 hours before needing a major overhaul. The average marine diesel engine will run for more than three times that long and log an average 5,000 hours under the same conditions.
What is a 454 marine engine?
The 454 used in Marine engines is essentially a truck 454 with heavy duty valves/springs and bronze freeze plugs(and some other parts) because they run at a continous higher rpm. As stated they are a very reliable and are typically set up to run 4400=4800 max and really are best at a cruise rpm in the. 3000=3600 rpms.
How much horsepower does a 454 Magnum have?
Mercruiser 454 Magnum MPI Models
The 454 MPI came in 2 different Hp version's being the 330Hp model which was known as the 7.4L MPI, and the 385 Hp 454 Magnum MPI Sterndrive Model and 380 Hp 7.4L Magnum MPI.
How much horsepower does a 5.0 MerCruiser have?
The 5.0L MPI MerCruiser sterndrive package typically has about 260-hp. The 350 MAG MerCruiser is called a 350 MAG and typically is rated at 300-hp. As you can see the engines are pretty much the same, except for the 15% difference in displacement and horsepower.
Why do marine engines run backwards?
The diesel engines on large boats and ships have a mechanism to reverse the valve timing so they can be started backwards. This eliminates the need for a gearbox.
Why are marine engines so expensive?
The boat engine (outboard) is expensive because they need to withstand the marine environment well, so all the parts used in making one are expensive stuff. And they don't sell numerous motors all the time, so to stay in business, they need to make a profit, so the price of an outboard (boat motor) is high.
How many hours on boat motor is too many?
Don't touch a motor with less than 25 hours per year (which implies low usage and probably the boat might have sat idle for a long time) and an upper threshold of 150-200 hours per year (which implies high usage and probably overstressed the engine).
How many miles per gallon does a 454 get?
The 454 is a big-block carbureted engine found in most older model Chevrolet cars and trucks. The engine uses eight cylinders to provide high-end torque and speeds. The combination of larger bore and eight cylinders equates to very poor gas mileage. The engine runs an average of 10 to 15 mpg.
How much fuel does a 454 burn?
A 454 will burn about 16gph at 3000rpms more or less depending on if carb or mpi.
How many hours will a 7.4 MerCruiser last?
While at the annapolis boat show this year, I spoke with the crusader dealer about life expectancy of gas motors, in particular the gm based 454. his opinion was , that with proper care and depending on how they are used , 3000 hrs or more is realistic.
