How to Choose Waterjet
Waterjet propulsion pump is a special marine propulsion device. Each waterjet model is suitable for certain operating conditions, and the same waterjet model also has different impellers to more accurately match different input conditions. Therefore, in order to choose the most appropriate type of waterjet and impeller type, must consider the boat, engine (motor) and waterjet matching condition. Only when the three perfectly match, can give full play to the performance of waterjet, so as to get satisfactory sailing effect.

We have prepared product catalog and simple selection forms for customers to consult. In order to more accurately select the right waterjet for the customer, we recommend that the customer fill out a questionnaire about the condition of the boat. According to the data provided by customers, we will choose the right model or give customized opinions for customers. All information provided by the customer will be kept strictly confidential and will not be disclosed to any third party.

Please go to Brochure page to download corresponding documents.
