    Hi, I am a newbie in boat building, can anyone provide what is the standard propeller depending on boat's length, RPM, carrying capacity of boat, engine HP etc. We have a plan to build a 62-footer FRP boat with inboard 6d14 engine with 2900 RPM. thank you in advance for someone who share their knowledge.

    There is no such thing as a standard propeller. It is part of the engineering of the whole design. Whoever designed the boat should be able to provide that information if he is a decent professional.

    Google “Vicprop”
    They offer a calculator for this purpose.
    Be aware that the results will be somewhat ballpark numbers, designed to give you a starting point, and you will still want to work with a reputable propeller shop before finally purchasing one.
