Often asked: How Inboard Boat Motors Work?

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’s better outboard or inboard motors?

Inboard motors generally last longer than their outboard counterparts. You can squeeze roughly 1,500 hours out of an inboard before necessary maintenance. Outboards, on the other hand, last about 750 hours on average. So, the inboard option means less maintenance (nearly half) even though they cost more initially.

What is the difference between an inboard motor and an inboard outboard motor?

The main difference between an inboard and an outboard engine is their placement in the boat. An inboard is hidden within the boat and an outboard is 100% visible. The boat on the left has an inboard or sterndrive motor and the boat on the right has an outboard motor.

Are inboard motors safer than outboard?

Inboard boats are the safest style of boat for pulling a rider, but if you do plan to pull a rider with an outboard or inboard/outboard boat then all of the same safety tips for wakeboarding with an inboard boat will apply, plus some extra precautions.

How long do inboard motors last?

An inboard engine can run for an average of between 1500 to 2000 hours depending on the type. As with outboard engines, maintenance is crucial to prolonging the usefulness of an inboard motor. Ventilation is crucial for an inboard motor and should be continuously checked; otherwise overheating could cause a fire.

Why are inboard boats so expensive?

An inboard motor will usually be more expensive due to it being located inside of the boat. This can make it more challenging when it comes to maintenance and repair. A motor that has a higher horsepower, that can reach higher speeds is going to increase the cost.

Are inboard motors bad for saltwater?

It doesn’t matter what propels your boat — inboard, outboard, I/O, jet drive — nothing on your boat that comes in contact with saltwater is immune to its corrosive powers. The greater the salinity, the faster the corrosion.

Is a 4.3 MerCruiser a good engine?

The MerCruiser 4.3L MPI makes good economic sense in infrequently used sportscruisers. The exhaust note is nowhere near as satisfying as a V8 but under load the V6 noise ain’t half bad! Thanks to Lifestyle Marine, Toronto, NSW – phone (02) 4959 1444 – for supplying such well setup engines.

How much do inboard boat motors cost?

If you run an inboard, expect to pay somewhere between $1,000 – $1,500. Most sailboats can do with a small 5 – 10 horsepower outboard engine without problems. These engines are easy to maintain and cheap to run.

Are outboards faster than Inboards?

Inboards on average can run 1,500 hours before tune-ups, while the outboard counterparts typically run 750 hours before service is needed.

Why are outboard motors so expensive?

Boat motors (outboards) are expensive because they are equipped with high-quality parts that are not only designed to resist constant working at max RPMs but made with materials meant to resist corrosion well. All of this needs significant work in R&D (more money), resulting in a pricey product.

Can you Wakesurf behind a stern drive?

Inboard boats, including direct drives and V-drives, are the only types of boats you can safely wakesurf behind. To recap, you should ONLY wakesurf behind an inboard board, never behind an outboard or inboard/outboard (stern drive) due to the risk of making contact with the propeller and the proximity of the exhaust.

How do you flush inboard motor?

Fill mixer cup with Salt-Away. Turn mixer unit to “rinse” setting and flush engine with fresh water for 5 minutes. Turn Salt-Attack mixer unit to “Salt-Away” setting and flush motor for 30-40 seconds. Turn engine off leaving the Salt-Away in the engine’s cooling system to protect the motor.

What does salt water do to boat engines?

Engines are made from metal, which is likely to corrode and rust from the saltwater without proper maintenance. Failure to remove the salt can lead to persistent surface corrosion of the engine. Boats that are built for saltwater have cooling systems with the capability to flush out the saltwater on their own.

Can you put any boat in saltwater?

The short answer is yes; you can use a freshwater boat in saltwater and vice versa. Because freshwater boats aren’t designed to resist corrosion, you’ll have to really clean your boat after each use. Rinse the saltwater off the deck and hull and flush out your engines every time you get back to the dock.
