Now this is a vessel of amazing ingenuity
0:03
And unfortunately, these things wash up a lot more often than you would like to think
0:07
but most of them are not this sophisticated. I mean, this one's got six 55-gallon drums that are crimped and welded together
0:15
with what looks like a two-cellular diesel engine in the middle of it
0:20
And this is what people are willing to get into and ride in for over 100 miles to leave Cuba to make it to America
0:30
There are about seven different ways that a boat is driven through the water
0:52
And each one of them has its own advantage for when you would want to have any of the different types of them on your boat
0:59
Then there are also about five different power options by which these different drives are powered in order to move your boat
1:06
Let's start off with a quick and easy one that really kind of covers both the power and the drive systems being wind
1:14
The wind can power a boat that has a sail that then uses a rudder in order to steer it through the water
1:20
Wind is great because it's free and doesn't require an engine in order to allow you to move the boat
1:25
which is why you can really cover both the drive and power
1:29
spectrum. The other seven, however, require some sort of external power to allow them to function
1:35
properly, which is where we get into talking about the other four different power options
1:40
that you will generally find on a boat. These are going to be your gasoline, your diesel
1:46
propane, and electric engines, and motors that will power the different types of drives that you
1:52
can put on a boat. Each one of these power options has its own benefits, like the diesel's advantage
1:58
of being used to create massive amounts of low-end torque that can move much heavier loads of weight
2:04
meaning bigger boats, more people, more amenities, and unfortunately slower speeds. But that's where gasoline comes in
2:11
Higher engine RPM, faster speeds, both with the ability to move less weight and less fuel economy
2:17
I'm not really sure what the real percentage is, but I'm guessing that about 65 to maybe 80% if not a little higher
2:25
of recreational boats use gasoline power. Then the remainder uses diesel. It's hard to figure in a percentage of the overall boat power market
2:35
when talking about electric or propane because electric is relatively new and propane is only used up to about a 25 horsepower engine
2:44
So the amount of these engines is a super low number maybe in the 1 or 2 if that of all boat power ranges The propane power source is a clean alternative and the electric power is also a really cool clean fuel source as well
2:59
Ingenity is the company that is coming in with the really clean-looking electric wakeboats
3:04
and it's an interesting new side of the boating industry. Now that covers the main sources of power that are going to run all of the different types of drives
3:13
that you can find on a boat. Now, this first drive is not the oldest type of drive
3:17
but it does have a section all of its own. So we'll start by covering the outboard first
3:23
Outboards have massive advantages when it comes to a choice for a drive for a boat
3:28
Outboard engines have the engine and the drive package all built into one
3:32
where the rest of the options are going to have separate components that make up the entire system
3:37
where you are going to have an engine and then other major components before you hit the prop
3:42
whereas the outboard has it all built into one and the lower unit that drives the prop
3:47
is bolted right under the bottom of the engine. Outboards have an advantage because of the fuel efficiency that you get with them, as well
3:55
as the fact that the way that they handle when it comes to the control aspect of boating
4:00
is probably the easiest for a beginner boater when comparing all the drive options
4:06
You can physically see where the engine is pointing, which is a huge advantage when trying
4:10
to dock the boat or turn it around in a tight spot
4:14
Because of the visual reference point that you get when you turn around, you turn around, and see the engine and which direction it is pointing
4:21
Another advantage of an outboard is that they are super simple to work on
4:25
because everything is right there in front of you, and once you pull the cowling off
4:29
the entire engine is sitting there at eye level when the boat is out of the water or on the trailer
4:34
This simplicity and ease of access is a huge value point, as well as the simplicity of the process to replace one of these engines
4:41
when the time or necessity comes, being that there are only four bolts that hold the entire engine
4:47
engine onto the boat. In comparison to any of the other five options with the exclusion of our
4:53
next type of drive being the fan power of an airboat. Airboats have a similar advantage in power
5:00
and drive because the engine is also sitting right in front of you on the deck of the boat
5:05
Though the engine style is pretty similar to some of our upcoming options, it does have some
5:10
differences because of the application for which it is being used. This is because the design of an
5:16
airboat is for a specific purpose, and not necessarily your conventional style of boating
5:22
An airboat's fan power allows it to push the boat across land and water and is primarily
5:27
used to get back into marshy areas that a normal boat wouldn't get you back into
5:32
It adds an extra level of adventure, hunting, exploration, and fun to the world of boating
5:38
Being driven by a massive fan blade as opposed to a prop it a really cool type of drive option when it comes to boating Moving on to the next five different styles of drives all of these next types are going to require a similar style of engine Whether that be a diesel or a gasoline engine all of them
5:55
have the engines mounted inside of the boat and will require some sort of transmission in order
6:01
to convert the engine power to the drive. Starting with a style that is similar to the outboard
6:06
let's talk about the inboard, outboard, or I.O. style of drive system
6:11
The name gives you an idea of how they are similar to the outboard, because the lower unit and transmission system can be found on the outside of the boat
6:20
and the engine on the inside. These will steer and maneuver similarly to the outboard
6:25
with the exception of not being able to see what direction the drive is pointed in
6:29
The drives are mounted on the back of the boat onto the transom. That's why you will commonly hear these called stern drives as well
6:36
but IOs and stern drives are pretty much the same thing. Both the stern drives and the outboards have an advantage over any of the other styles we discuss
6:45
because these drives have the ability to trim the drive and change the angle of the prop
6:50
which makes a massive difference when it comes to control and efficiency
6:54
But we've got another video here that will show you why that is and how to use it
6:58
These are a super popular type of drive system and are still found on many boats today
7:03
though they aren't as popular as they used to be, they are still really prominent in many types of boats
7:09
and I don't see them going away anytime soon. One of the similarities between these drives and our next style is the position of the engine
7:18
Because the transmission portion of the drive is located on the outside of the transom with the lower unit attached to it
7:24
the engine has to be placed in the back of the boat, which, when it comes to a boat
7:29
one of the most important things that you have to think about in the type, build, and form
7:33
placement of stuff in the boat is the weight in where it is located, which plays a huge part
7:39
in the performance of the boat. Our next style also shares the same necessity in the engine location
7:45
and having it to be in the back of the boat, being the drive power of a jet boat, where the boat
7:51
uses a jet drive system that sucks up water from under the boat and then uses that water
7:56
to spray it out of a jet from the back of the boat that then propels the boat through
8:01
the water. Jet boats have a big advantage in a drive type because they can operate in extremely
8:06
shallow areas of water. Though they do have the ability to pull water from around 10 feet below the
8:12
boat, they can still operate in only inches of water. Something that many people probably don't
8:17
think about with this though is that running them in shallow water, say where there is a lot of
8:22
grass, they will suck that grass up and clog up, leaving the boat inoperable. But it can be easily
8:28
cleaned out and make you operable again these boats have a very different experience than any of the other boats when it comes to controlling and maneuverability Because they use the force of a water jet stream to propel them they can get really slighty when it comes to driving them in tight spots or when docking
8:46
So that takes some getting used to. Now because they have the engine in the back of the boat, it's also similar to our next type
8:53
of drive system being a pod drive style. Pod drives are the newest type of drive system that you can have on a boat, though they
9:00
aren't that new and have been out since 2005 when Volvo Penta first came out with the
9:05
pod drive design of the IPS, they are still an interesting type of drive, where the transmission
9:12
and lower unit are all incorporated into a pod drive that goes through the bottom of the boat
9:17
an interesting aspect of a pod drive is that the entire pod turns altogether for the steering
9:24
and that the props are generally in the front of the pod, as opposed to behind or on the back
9:29
of the lower unit. These forward-facing props have an efficiency aspect to them because they
9:34
are able to hit what is called clean water and the other styles are all hitting turbulent water
9:39
when it finally gets to the prop. Though now pod drives can be found on outboards like Mercury's
9:44
V-12 engine, they are more commonly found on diesel inboard engines, which is our next type of drive
9:50
system being a true inboard style of boat. An inboard usually has the engines closer to the
9:57
middle of the boat because they utilize a drive train that then has a straight shaft that goes
10:02
through the bottom of the boat and then has the prop on the end of the prop shaft. These boats will
10:07
steer a little differently as well from any of the others that we have already discussed because
10:12
they use a simple rudder system to direct the water flow that is coming from off the prop. Most people
10:18
will find these and the jet boats to be the hardest types of drives to control when it comes
10:23
to being able to dock the boat. But because of their design, They are the most proficient type of drive package for water sports
10:31
Wakeboard, surf, and ski boats all usually utilize the inboard design of a drive
10:36
I think that many people also prefer this design on a boat where people are commonly in the water around the back of the boat
10:43
Because unlike the stern drive where the prop is sticking out the back of the boat
10:48
and inboard has the propeller being under the boat, giving a lot of people a more safer and comfortable feeling when there are people in the water and getting in and out of the boat
10:57
Just like the inboard, another, what I guess you could call subsection to the inboard system
11:03
is going to be your V-drive type of system. This is basically the same thing as the inboard
11:09
with the exception that it uses a transmission system that has the gearbox in front of the engine
11:15
and then uses basically a V-gear system in order to transfer the engine power to the prop shaft
11:21
that then again is under the boat, and also uses the rudder to direct the water flow in order to start
11:27
steer the boat and control it as you go through the water
