>>>You think the sib is for river use only?
No I was meaning that was an older Honda OB and my experience of the earlier ones were they suited being bolted to a river boat as they were so heavy.
I wonder how the seller sees the value split. If you bought the outfit (that's what I would do if I wanted the Futura) and he accepted an offer of say £850-£900 I reckon as long as the Honda runs nicely it might fetch £750-£800 leaving you a Futura with its remote setup for £50-£150. Plenty of scope to have a pro repair and you'd get a very interesting classic.
But only if the floor is correct/present. Interestingly all the images on the net for the Junior model shown the floor looking the same... red and a bit "loose". I wonder as they don't have a central keel and the floor plays no part in performance on the plane if it is different to the HP air floors as we know them now?? Perhaps it is as it should be but the guy doesn't know enough about them to give a proper answer??
See these images from a foreign forum 9yrs ago... note the glue has failed on that one...
