Benefits of technology

"The patent text discusses the problem of audio and electrical systems in small personal watercraft being subjected to more vibration and splashing than current marine audio systems can withstand. Additionally, when these systems need to be serviced, the entire watercraft cannot be used because parts of the system may leave large holes in the hull. The solution proposed is a water jet propulsion boat with a separate electric unit that can be easily connected and disconnected from the boat without using tools. This allows for easy servicing without having to remove parts that may leave holes in the hull."

Problems solved by technology

Further, when such a system needs to be serviced, the entire watercraft cannot be used because parts of the system that removed may leave large holes in the hull of the watercraft, leaving the watercraft unusable.

Embodiment Construction

[0045]FIG. 1 is a side view of a water jet propulsion boat having an electronics unit according to an embodiment. The embodiments disclosed herein are described in the context of a personal watercraft because the embodiments disclosed herein have particular utility in this context. However, the embodiments and inventions herein can also be applied to other boats having other types of propulsion units as well as other types of vehicles.

[0046] The water jet propulsion boat of can include a body 1, which can be made up of a lower hull 11 and an upper deck 12, as shown in FIG. 1. In the body 1, there can be provided a water jet propulsion device 2 to propel the body 1, and the like. However, other types of propulsion systems can also be used.

[0047] The deck 12 can be raised upwardly at a central portion of the body 1. On the raised deck portion and on the forward end of the body, there can be provided steering handlebars 12A configured to be operated by a rider to change the direction...

Abstract

A water jet propulsion boat has a water jet propulsion device in a body, and is propelled by the water jet propulsion device. An electric unit having a waterproof structure and being separate from the body can be removably disposed in a storage section without using any tools. The storage section is defined by a recess provided in the body and being open upward.

Description

PRIORITY INFORMATION [0001] This application claims priority to Japanese patent application Serial No. 2006-014593, filed on Jan. 24, 2006, the entire contents of which is hereby expressly incorporated by reference. BACKGROUND OF THE INVENTIONS [0002] 1. Field of the Inventions [0003] The present inventions relate to electrical units for watercraft. [0004] 2. Description of the Related Art [0005] Water jet propulsion boats are conventionally used generally for recreation. Although small personal watercraft are often times operated at elevated speeds, these boats are also often used for touring and cruising at lower speeds. Some boats, including small jet-propelled watercraft also known as “personal watercraft,” are equipped with audio units. For example, Japanese Patent Document JP-A-Hei 10-338191 discloses such a watercraft. [0006] The audio unit of the JP-A-Hei 10-338191 reference includes an amplifier and speakers. The speakers are fixed on both side faces of the body of the boat...
