Saildrive Propeller Options

Propellers are a specialist subject and a full understanding needs a propeller specialist. Whilst Beta Marine has many years of experience learning which propeller normally goes with which engine, we can give only give you general guidance, please note that we are not propeller specialists. With the SeaProp 60 there is a maximum propeller diameter of 18 inches and we offer either:

  • 3 Blade fixed or
  • 2 blade folding

Propeller Dimensions

Propellers are normally measured in two dimensions:

  • The actual diameter (frequently measured in inches).
  • The pitch – assuming the blade is set at an angle, then if you followed this angle through one revolution and measured the distance between the starting and finishing point, you will have moved forward the measurement called the pitch.

The propeller size is often limited by the actual space available when trying to fit it in position. These size limitations are frequently the diameter, due to the space limitations between the position of the propeller shaft and the underside of the hull. This can be compensated for by changing the pitch, but there are limitations. For futher information on propellers, please look at the individual manufacturer’s websites for information:
