Henleys Propellers Propeller Specification Sheet

Henleys Propellers and Marine Ltd requires a Specification Sheet to be filled out when ordering a custom built propeller, either for a new vessel or a replacement propeller. The data supplied by the customer is used to analyse and calculate propeller dimensions. This undertaking, combined with our practical experience for more than 75 years, helps ensure the best possible choice of propeller for each application.

Accurate Detail Input- Calculations are based on the information the customer provide to us. Inaccurate vessel and engine information will mean an inaccurate result, so please take the time to check your details. Speed Predictions and propeller pitch are approximate only and dependent on the efficiency of the hull design. For more accurate speed estimates, please supply hull resistance data which can be superimposed over the propeller dynamic thrust curves.

By completing this form you agree to a NZ $200 service fee. With this fee we will provide you with the propeller dimension and expected performance. However this amount will be deducted from the total invoice upon your purchase of new propellers or whenever adjustment is needed to your existing propellers. Henleys accepts payment through credit cards, cheque or direct credit to Henleys nominated bank. This service fee only applies to non-account holders.

If your requirement is for an outboard SOLAS propeller, please fill out the SOLAS propeller specification sheet.

Alternatively you can fax your details to Fax: +64 9 443 5892 by printing a  specification sheet.
