thanks for that. yes at the revs we use cast props are the only way but can be expensive to buy then find you need a few more mm or a few less so cheap props can be handy to get an idea, the difference a good brass cast prop from prop shop makes is worth the money and lack of vibration you get, the thing is to try and keep all your boats on similar props then you can try them off other boats, Paul found P M Devlin that the shaft needed to be updated to 5mm so all our supply of props where no good as they where mainly 4mm
