Before we get too far, lets just take a quick look at the four most common boat motors. The chances are you are well aware of the type of motor you have, but to make sure that any new boat owners know the best way and what to look for when they are winterizing their own boats. Not all winterizing steps are needed different types of boat configurations, on the other side of that when you are winterizing a larger boat with a head, or utilities onboard its important to ensure that you understand how to properly shut those down for the winter.
There is nothing worse for us to see people disappointed in the spring time when they have missed a step and caused an issue that delays them from getting out on the water. Don’t get us wrong, we enjoy seeing you and appreciate the business; but for us you enjoying your boat and saving time and money makes us much happier!
The inboard motor is mostly used for large boats that are longer than 26 feet. It is mounted inside the vessel, with its shaft attached to the propellers. This boat motor is usually positioned at the center of the boat in order to facilitate equal weight distribution. Inboard motors are generally quieter than most boat engines and have more gas mileage; with a rudder located behind the propeller controlling the steering of inboard powered vessels.
The outboard motor is the most popular and widely used engine for propelling small boats. It is designed to be attached outside the boat transom and consists of three components: a self-contained unit that holds the engine itself, a propeller and gear box. Outboard motors are small, light in weight and quiet. Besides this, they have more horse power per pound of weight, as compared to most boat engines.
Jet Drive Motors
This type of boat motor is fixed inboard and does not include propellers. It is believed to be safer and more eco-friendly than most other boat motors because it does not disturb marine life. A jet drive motor works by sucking water through a pump that is powered by an impeller, and then discharging it at high pressure through a nozzle. It is this process that propels the boat forward.
Stern Drive Motors
Also known as inboard/outboard engines (I/Os), stern drive motors are among the heaviest and most powerful boat engines. They have a combination of features found in both inboard and outboard engines. They are four-stroke engines that are self-propelled, and usually mounted inboard with a unit fixed to the transom. Boats that use stern drive engines are steered by the outdrive which rotates like the outboard engine, propelling the boat forward.
