Our second form of propulsion when it comes to the Inboard engine model is ‘True Inboard’ propulsion, so called because it is completely set into the hull of the boat. This model is excellent for small boats for wakeboarding and skiing but its efficacy wanes as the size and weight of the boat it is powering increases. If you go with an inboard motor, the Closed cooling system is the better choice, as a Raw cooling system is going to involve dirty water and this can be problematical without a lot of regular cleaning. The main difference is that a ‘raw water system’ employs immersing the engine in water without the presence of heat exchanger technology, and a closed system utilizes tubes and is similar to an automotive cooling system, employing water rather than air. And with inboard engines this is accomplish in one of two ways, either a ‘closed’ cooling system or a ‘raw water’ cooling system. A system of this sort requires a lot of cooling, for one thing. This is a great option for shallows and for very small boats but there are some caveats. The Jet Drive sucks in water and then expels it at high speed, using the water itself as your means of propulsion. You see, this model does not utilize propellers at all. Probably the coolest sounded name for a means of propulsion, this is also known as ‘The Jet drive’ and it functions in an interesting manner. This type is most commonly seen in 3 flavors and as the name suggests, this form of propulsion is more ‘hidden’, being set into the boat where consequently it’s a bit safer when it comes to water sports (due to propeller being absent or simply in a further proximity from where anyone can get hurt). Inboard engine propulsion is a completely different beast. The upper section typically houses your power with the middle containing the engine proper and the lower portion, of course, your propeller. It has some advantages and some disadvantages which we go into later but for you all we need to know is that this is an exterior motor, bolted into the transom typically with 4 to 6 bolts to keep it secure. This is the most common that you will see and it’s got a lot of power. We’ll start with the simplest, the outboard engine propulsion model. Outboard motors – Understanding your outboard engine Let’s go into a little more detail about the two types just to make sure that things are crystal clear. With the outboard it tends to be similar, although you do get a little variance such as with trolling motors. Some of the different types of inboards, for instance, offer greatly varying forms of propulsion that may or may not be ideal. While this is it in a nutshell, there is a bit more to it. Let’s talk about what makes these pleasure-crafts GO! I know, I know… one type is on the inside, one is on the outside Outboard motors so that you know what type of propulsion you want for your boat in advance as well as the pros and cons of each. In today’s article we are going to discuss Deck Boat Inboard Vs. When you are shopping for the perfect deck boat you are going to hear a lot of new terms and it is a good idea to learn a little about what you can in advance. For those of you are just entering the world of pleasure boating we’ve got a little tutorial today.
