MerCruiser Inboard Engines

MerCruiser inboard engines can be used on many types of boats. All of their parts, minus the propeller, are contained within the hull rather than the exterior. They also operate differently than outboard engines, so there are a few things you should know before purchasing one.

What size boats can run on MerCruiser products?

Some MerCruiser engines are for yachts and other types of large boats, but there also are products designed for small speedboats that hold two or three people. There are more than 4,000 MerCruiser products to choose from to ensure that you get the right one for your boat.

How long does an inboard engine last?

The product and all its parts can last for many years. The number of years depends on how often the MerCruiser product is used and the power source that it utilizes. If the power source of the MerCruiser motor is gasoline, it can be expected to run for 1,500 continuous hours before needing substantial repairs. If diesel is the power source, it can be expected to run for as long as 5,000 continuous hours. Diesel inboard engines are most effective for larger vessels.

How do you winterize inboard engines?

Antifreeze is needed to keep coolants in the MerCruiser engine from freezing during the colder months. If antifreeze is not used during the winter, the engine may no longer function. In addition, the boat engine can become damaged by the bursting of pipes as a result of freezing. You will also need gasoline stabilizer for the winter. Here are the steps you need to follow to winterize a marine craft:

  • Run the engine and bring it up to operating temperature.
  • Treat the fuel system.
  • Replace your fuel filter.
  • Change the oil.
  • Drain seawater from the cooling system.
  • Prepare the drive train.
  • Take steps to ensure that other parts of the engine for your marine craft function properly.
What is the gas mileage of a MerCruiser engine?

Fuel consumption varies depending on how fast youre traveling and the specific MerCruiser engine that you have. Some products use as little as 5 gallons per hour while traveling at a moderate speed. Some of them can use as little as 1 gallon per hour when idling or moving at a low speed.

How are inboard boat engines cooled?

Water is drawn into the system using a belt, and its often brought in using a hull fitting. However, the water can also be brought in by a pump in the stern drive of the marine craft. The water then passes through either the inboard or the outboard, and it leaves the boat through the exhaust. The way that they are cooled makes inboard motors distinct from outboard engines.
