How much does it cost to repower a boat to diesel?

A complete rebuild of an older diesel or gas engine is within $1,000 to $2,000 of the price of a new engine, and the rebuilt powerplant sometimes retains its starter, alternator and transmission.

How do you winterize a diesel boat?

Let’s get started!

  1. Stabilize the Fuel. Check your fuel-water separator for sediment and water, and clean or replace the elements as needed.
  2. Change the Oil.
  3. Coat the Cylinders with Oil.
  4. Winterize the Cooling System.
  5. Two Types of Antifreeze.
  6. Three Levels of Concentration.
  7. Check the Exhaust System.
  8. Inspect Hoses.

Can I put a diesel engine in my boat?

Answer: In principle, a diesel engine is a diesel engine, so an automotive diesel will work fine in a boat. And, in fact, many marine diesel engines are nothing more than “marinized” car or truck engines. The engine will want a water-cooled exhaust manifold and a wet exhaust (a dry exhaust is too noisy).

Is repowering a boat worth it?

Repowering an outboard-powered boat can be a viable option for an owner who either can’t afford a new boat or who simply loves the boat he already has but wants new power. New motors will breathe new life into the boat and often improve performance and fuel efficiency.

What does it mean to repower a boat?

Repowering is exactly what it sounds like – getting a new and better power source behind your boat. You can choose to rebuild your existing engine, or get a new one. Either way this cost-efficient option is a great alternative to buying a new boat or continuing expensive maintenance on an aging engine.

Do diesel engines need to be winterized?

Tip 1: Treat the fuel. Fuel needs to be winterized, especially if the equipment will be used throughout the winter. Paraffin wax is present in all diesel fuels as a natural lubricity agent. These can come out of suspension and cause fuel to gel, which clogs the fuel filter.

Is there a difference between marine diesel and regular diesel?

Marine diesel oil (MDO) is also composed differently than regular diesel fuel. Unlike the diesel you fuel your car with, MDO contains some heavy fuel oil….

Is there a difference between diesel and marine diesel?

On-road diesel fuel was limited to 15 parts per million of sulfur content while off-road diesel (for boats and generators and other non-road uses) was allowed to be higher sulfur. More sulfur in marine diesel meant better resistance of microbes in storage and improved lubricity of marine diesel fuel.

Can a gas engine be repowered to a diesel?

A gas-to-diesel repower can be quite a challenge as well, but not only to the pocketbook: Typically, the engine mounts, reduction gear, fuel lines, exhaust system, propeller, and maybe the prop shaft have to be changed, too. Diesels of similar horsepower are usually bigger than gas engines, so that could mean a space issue.

Where is the best place to repower a boat?

Choose a well-established, reputable, full-service yard with lots of repower experience, and with a staff of factory-authorized service techs with the training and tools for the brand of engine you’re buying.

Can a boat be repowered before it wears out?

Those who buy new, or even moderately used, boats will probably trade up, down, or sideways before their engines wear out, and will never face the Specter of Repowering. (If my engines were getting long in the tooth, I’d trade for a newer boat and let someone else deal with it.)

Which is better for a boat gas or diesel?

Boat owners must weigh the advantages and disadvantages of switching their engines from gas to diesel. Any marine surveyor can tell you he or she has seen plenty of boats that made the switch from gas to diesel engines. Diesels are superior in many ways, ranging from reliability to fuel efficiency.
