Thanks for that, I have managed to get the manual and as nasher said it needs a slide hammer, should be able to get something together, bigger problem seems to be that according to a couple of friendly outboard repairers the suzuki gearbox is "Like Chocolate" and tend to split as you withdraw the unit so it is filled with parafin at present and then we will tease it out, hopefully.
I will post to let you know how we get on, thanks again for the help
On a different not we blew the tubes up today to see what repairs we need to make, 1 rear starboard tube ok other rear tube not sure about, bow tube has leak, now need to trace leaks.
Taxi bill bought the boat from craidiver as a rebuild project, I would post some pics as it was bought but do not know how to resize them, we have stripped back and done most of fibreglass work and are ready to reattach tubes, we are then going to turn over and work on undersides. We intend to make any repairs to the hull and then use flocoat.
