Cool thanks.
This one lives in a garage so that makes sense.
Also found the repair kit instructions in the back of a kitchen drawer- with a Zodiac legal bit at the bottom. Also helpfully told me to go to my dealer for more glue and toluene!
At least I now know what I'm looking for.
Many thanks.
My aux will also thank you as it now won't be pushing umpteen gallons of water around- and 5 hp is on the lower limit of entertainment for that boat even if the inappropriate long shaft makes it entertainingly twitchy!
