Boat propellers: performance and efficiency start with the right set-up
The propeller is a key performance factor: it influences acceleration, gliding behavior, top speed and the speed range under load. In this category, we bundle propellers for outboards and sterndrives, including matching hub kits and accessories.
Outboard vs. sterndrive: selection by system
The mount, hub and propeller geometry differ depending on the type of drive. Custom-fit aluminum and stainless steel propellers in various dimensions are available for sterndrives (e.g. MerCruiser Alpha/Bravo).
Aluminum or stainless steel?
-
Aluminum propellers are economical and a solid standard solution for many leisure setups.
-
Stainless steel propellers are generally stiffer and - depending on the setup - can offer more precise "bite" and more robust edges.
The optimal choice depends on the boat, engine power, area and usage profile (touring, water sports, load operation).
Diameter × pitch: how to make the right decision
The most important parameters are diameter and pitch. The rule of thumb is:
-
More pitch → tends to have a higher top speed, but higher load
-
Less pitch → better acceleration/load absorption, possibly higher speed
The aim is for the motor to run in the recommended WOT speed range (manufacturer's specifications). (Here you can also integrate a short "pitch guide" as an info box in the store).
Interchangeable hub / hub kit systems: Flexibility and economy
Propellers for interchangeable hubs (hub kit systems) offer the advantage that the hub is selected to match the motor and the propeller body can be flexibly combined. This reduces conversion work and makes changing the propeller more economical - especially if there are several engine variants or a replacement propeller strategy.
