Look we’ve had twins!
Are they identical?
Hang on we’ll check. Er no the blades oppose each other.
Which one is called Port and which Starboard?
Inspirational flash – we photograph everything…do we have an ID photo of the twins before removing them?
Yes thank goodness let’s put them back. Of course the very last under the waterline job and the M6 button head hex bolt sheared like butter….are we going back in as planned? Run up the tree house and retrieve left spiral drills, mole grips and extraction set not looking forward to a late night; but out came the stud with pliers. So now the worry is will the stern thruster twins stay put or whiz off into the deep? Lots of Loctite applied.
