Hi Jaco!

To start to answer your question quickly we need to know the model number and letters stamped on your motor's crankcase just above the top of the driveshaft casing tube plus a picture or at least an accurate description and some measurements of your prop. (Diameter & number of blades etc) You could also have a look at the main site descriptions and pictures of all the models to compare what you have on your motor.

or , if I ignore the wrath of the management here, have a look at

If all this doesn't answer your question come back let us know.

Have a look around at one of the links I posted before:

This is a clutched WC 102 model from 1970, the same year as yours. The first measurement to make is the overall diameter of the circle passing through the tips of the blades.

Hi Jaco - was the previous owner sure the prop is wrong for the motor? Several shapes were used on 102's over the years, ranging from one which looks like one that would be correct for a 40 Plus (4 bladed), one referred to as a 'bow-tie' prop as it resembles a bow tie surprisingly enough (two bladed), and a three blade semi weedless type.
Some or most props have the motor they were intended for cast on the hub of the propellor - eg Forty Plus, Century, 102 etc. are there any clues like this on your prop?
Most folk wouldn't get too precious about prop diameters - just locate a prop 'suitable for a 102', and then with any preference you might have for two, three or four blades. Either way, you wouldn't be making and sweeping changes as far as perceivable performance goes. (I've now opened the floodgates of opinions as to why certain shapes are far superior to others!!)

Props!

Really Confusing, the variations for 102s!



True "Weedless" this one.

True "Hopeless" as well.............

Hello again Jaco - since my last post, I have waved a school ruler at the three 102 props I have - they are all about 9" (230mm) diameter regardless of type if this helps you make a quick assessment. Rick.
