Description

Technical Field

[0001] The invention relates to the technical field of outboard motors, and in particular to an outboard motor structure capable of changing the water depth of a propeller. Background Art

[0002] Outboard motors are power devices for boats, ships, and boats. They are usually installed at the stern or side of the boat. When working, the lower part with the propeller is immersed in the water, and the boat is pushed forward by the reaction force of the high-speed rotation of the propeller and the water. Outboard motors can realize the forward, turning and backward movements of boats. They have the characteristics of compact structure, light weight, easy loading and unloading, simple operation, and low noise. They are suitable for use in inland rivers, lakes and offshore.

[0003] However, current outboard motors generally do not have the function of adjusting the launching depth, which means that it is necessary to select the appropriate length of the outboard motor according to the size and draft of the boat. Especially for boats of special sizes, the lengths of outboard motors available on the market may not be suitable, which will bring a lot of workload to the user in selecting the outboard motor.

[0004] To this end, the present invention proposes an outboard motor structure capable of changing the launching depth of the propeller, so that the outboard motor product can match the launching depth requirements of different ships to a certain extent. Summary of the invention
