oh and I forgot to say DONT put a water lube bearing on the inboard end of the tube, it will eventually knack ya shaft and you will be losing the effect of having flexible mounts on the engine.
stern tube glassed in at almost max angle

I intend removing the inboard cutless bearing .I should like to ask if the outboard coupling will adequately be supplied with enough water,for cooling & lubrication since i am using a volvo seal and there is no provision for a water supply forward of the ouboard cutless.

I may have missed this, but, was the shaft glassed in with epoxy or polyester? The former would be removable with a heat gun without damaging the hull built of the latter. (on the assumption the shaft log is polyester/glass)

Thanks everyone for all the excellent thoughts above.
Downwest, the shaft log / stern tube was glassed in with polyester resin. Hence it will be quite a major job to cut it out.
Rachel, re swopping the gearbox for a down angle, thats not so easy on a little island that does not have a Yanmar dealer! That would be the ideal solution, but it would involve shipping in a new gearbox, and then either returning the old gearbox to the supplier or trying to sell it locally (but there would be virtually no demand here for a 1GM gearbox).
TNX for the confirmation re NOT putting a cutless bearing on the inboard end of the shaft log.
Re the bearing in the aft end of the shaft log, I am wondering if it would be wise to build a couple of water intake ducts on the side of the shaft log to feed cooling water in to the forward end of the cutless bearing? Rather like the ducts that a traditional bronze stern tube has.
Fisherman, your suggestion re using sand as a packing material and then glassing over the top is brilliant!

Three years later, here is an update finally on David's engine.
It didnt take this long to install, rather, its taken me a while to catch up with David. I saw the boat hauled out at the Yacht Club last week,with David on board, so went and had a look at the final installation, and took some photos.
The beds were cut out and 're-done' in the end, similarly the stern tube, and David reports that it all works very well now.
The fuel tank is a standard 10 gallon re plastic petrol tank for an outboard motor with a hose barb for the return line epoxied in the top, and located in the forward cabin.
The Aquadrive is bolted to a plywood mini-bulkhead that was bonded in, and works well.
Photos of the original beds are on page 1 of this thread.
Here is Peiliesje on her trailer at the Yacht Club :
David has built a nice plywood box over the engine :
Here is the new Max-Prop :
