Propeller clearance

[zenataomm]

Peter Thompson of "Lister" and Uxbridge fame once told me in the 80s.

When it comes to prop clearance, the most common profile of wood jettisoned into the cut and therefore most likely to try to pass between prop tip and uxter is 2 X 4.

So 4" clearance is recommended.

Maybe wood was thicker in the good old days... 😉

 

I'd have thought anything coming between Colonel's prop and the skeg/uxter is unlikely to survive the encounter, given the size of the prop and the weight of a Bolinder flywheel...

 

Haven't seen Pete for years -- last photo I've got of him was at a music session in the 80's. Folkies may just recognise the callow youth between us, who was learning at the time... 🙂

If anyone wants a prop refurbisher closer than the south coast, then here is always Steel Developments of Merton. We used them for all our OB props in the 70s, and they do yellow metal ones as well. I can't remember who we used for bronze props, but probably Norris.

we used to send the outboard props to Chas Newens but I think they probably just took them to Norris and charged a 'well to do people who live by the River' surcharge.
