Speed pulse ring.

As I mentioned during the proshaft install I thought I may have to remove the prop to fit the speed pulse ring which I had designed.

The theory was that a toothed ring would be fitted to the propshaft and an inductive sensor used to drive the speedometer. To this end I designed a suitable ring.

I then sourced an engineering firm and had it made.

Creative Water Jet were chosen and after many discussions with Richard Miles at Creative Water Jet about the design and how best to do it the parts were made and delivered.


I even got as far as starting to paint them. However a quick chat to Andy B and the plans have changed!

Andy was concerned that the prop would move around under load (something Richard also voiced but I in my wisdom decided to gloss over!) and that the the prop tube may not be totally round.

Andys preferred option is to stick magnets to the diff input flange and mount the sensor there, so thats what Im going to do.

So if any can think of a use of a very attractive aztec style sun let me know!!
