What Fuels wur used to power modern ships?

User Avatar

Asked by Wiki User

Different ships use different fuels according to their needs. Most large cargo ships use bunker fuel which is a form of crude oil. Some ships use diesel fuel. Some modern commercial ships are employing nuclear fuels. Some military ships use diesel for their normal operating engines and for more speed they will use jet fuel for gas turbine engines.

Depends on HP and year. Older ones you normally had to pull the power head (engine) and disconnect the gear shift before pulling the lower unit. Look for a service manual on eBay for your year and model to be sure.

Whats the fuel-oil mix ratio on a 1994 Honda CR125?

User Avatar

Asked by Wiki User

I usually work it at about 50:1 ratio. That's 50 parts petrol to one part 2 stroke oil. You might find it useful to purchase a small mixing cup (like a Ratio Rite). It'll let you mix easily no matter how much fuel you have.

if you were smart you would run 40:1 and have your bike last longer.

-Most manufacturers recommend 32:1 ratio as this provides the best lubrication and will prolong the life of your piston and cylinder. If you run too lean (ie-50:1, you will go through pistons and cylinders much quicker) The only problem with running too much oil is you can foul plugs, so it will take a little trial and error as each bike is a little different.

I personally run about 38:1 (according to the ratio rite cup) on my Suzuki RM 125. Keep in mind, if you run less oil, you are also making your bike run richer, so you may have to adjust your carburetor jet settings to compensate for it. Your best bet is to call your local Honda dealer and ask them the correct ratio for the bike, better yet, get the repair manual. (and definitely don't run 50:1 unless you like frying your piston)

What is the fuel mix for a 1986 evinrude outboard 4 hp?

User Avatar

Asked by Wiki User

The formula is ((gallons of gas x 128) / mix ratio) or ((4 x 128) / 40). The true answer is 12.8 ounces for you, but if you were to put 13 ounces of oil in because measuring tenths of an ounce is hard to do, it would be okay.

What is the purpose of an ignition coi?

User Avatar

Asked by Wiki User

The ignition coil creates the high voltage necessary in spark plugs to create the spark that ignites the gasoline fuel that creates the expanding gas that pushes on the cylinder making it move and turn the crank shaft of the engine. The rotating crank shaft powers the fuel pump, alternator, air conditioner. The rotating energy is passed to the transmission and to the drive shaft and wheels making the car or other gas powered vehicle go.

What fuel does a ship use?

Asked by Wiki User

It depends on the type of engines that the ship has, but most large cargo and container ships use heavy fuel oil called bunker fuel. In some cruise ships, they burn bunker fuel to spin electric generators that produce electricity for motors. Smaller vessels use various types of Diesel.

How do you remove a starter from a mercruiser 3.0 liter 4 cylinder inboard motor?

User Avatar

Asked by Wiki User

Remove power connections from battery. Remove the wires to the starter. There are 2 bolts, one short, one long, that go from under the starter upwards. Remove these 2 bolts, loosing them each a bit at a time and holding the starter up to keep the turning easy. It is all basically a 'no-see' job, have to go by feel.
