How do boat motors work?

The crankshaft turns the main driveshaft running down the long spine of the motor. A small gearbox at the bottom of the driveshaft converts vertical spinning motion into horizontal spinning motion. The propeller powered by horizontally spinning gears powers the boat through the water.

An inboard is a four-stroke automotive engine adapted for marine use. Inboard engines are mounted inside the hull’s midsection or in front of the transom. The engine turns a drive shaft that runs through the bottom of the hull and is attached to a propeller at the other end.

One may also ask, can I use a car engine in a 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).

Can you start a boat motor without water?

Running the engine without a water source for any length of time will cause damage, so you‘ll need to attach a hose to the motor’s water intakes. Some newer motors have built-in attachments that accept a hose nozzle. If your motor doesn’t, you‘ll need a set of motor flusher muffs.

How many hours on a boat engine is a lot?

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.

How often should you service a boat motor?

You should have your motor serviced and waterpump impeller changed every 2 years or every 100 hours.

How do you check Boat Engine hours?

Inspect the engine for an installed hour meter. The meter can usually be found above the engine or somewhere around the steering area of the boat. The numbers on the meter show how many hours the engine has been in use. If there is no hour meter, one should be installed by a marine mechanic.

What size motor can I put on my boat?

The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower. For example, a 5,000-pound boat could have an engine with between 125 and 200 horsepower.

What causes a boat motor to lose power?

You most likely have a filter problem or fouled plugs. That could be why your boat motor is losing power. Prevention: It’s possible to buy a bad load of fuel, but it’s more likely that the fuel went bad while in your boat. Leaving a tank near empty for long periods of time can cause condensation and water in the gas.

Can you run an inboard boat motor out of water?

If you run an inboard out of the water you need to be very aware of the prop under the boat. Some reverse gears will drag a bit when in neutral (or if accidentally put in gear) you will have a spinning prop under the boat. Pets and children can sneak under a boat without being seen.

What are the advantages of an inboard motor?

Advantages of Inboard Engines Inboard engines are favorites for water sports like wakeboarding and waterskiing, especially with multiple skiers, as they have better wake control, major towing power and a clear transom for tow ropes. A lower center of gravity also helps to cut through heavy ocean waves.

What boat motor is best?

Best Outboard Engines Honda BF6. Suzuki DF25. Yamaha F25. Mercury 75/90/115. Torqeedo Deep Blue. Suzuki DF90. Yamaha V-Max SHO 115. Evinrude ETEC G2.

What causes an inboard motor to overheat?

Worn or damaged water pump/impeller, clogged passages, cracked/kinked hoses, among other things can easily create an overheat condition, which is one of the deadliest conditions a motor can face. There are two types of cooling systems commonly found on inboard/outboard boat motors.

What causes a boat motor to overheat?

The most common cause of outboard motor overheating is water pump failure. Lack of raw water flow and lack of fresh water can cause water pump failure. Lack of fresh water can be noted if there is a large increase in temperature between the inlet and and outlet of the heat exchanger.

Why do boats have multiple outboards?

Most boats are fitted with a powerful outboard (or multiple outboards) to accelerate to the fishing spot. After reaching the fishing spot, they switch to the smaller lower power engine for low noise levels. Trolling of fish needs low noise levels.
