Hello All, I am new to your Site, but have read these particular Postings with interest. I am currently researching this aspect, and have found what I have so far personally proved to be a 'sound' compound for this appliciation, but I am continuing to test it before saying anything further. Further reasearch proving what I hope/believe, a 'product' will result... one that is efficient, lasting, and flexible at all speeds, but, more importantly, as water resistent as possible - not only for our vessels benefit but more importantly for the environment we sail our vessels in - a responsibilty all will agree with I'm sure. Present prop. shaft construction and 'greasing' technology leaves much to be desired as it stands, and, basically, in todays world, it is somewhat 'archaic' and basic to say the least: this is now being seriously 'looked at', and, the day is not far off, when innovative, more simple, easy, and
'modern' alternatives will be realised. Maybe present manufacturers are content to live in the past... but maybe it's time we moved on? Are there builders out there who would want to look and use viable new innovative alternatives? - if not, my ideas will keep... for the time being anyway! Patents can be excellent investments!
