For checking the gear change rods. On this engine, part way down the leg you will find a longish hexagonal nut which connects the gearbox gear change rod to the engine lever rod. The long nut is locked with thin nuts. Move the engine lever to check that the rods are properly connected together. If the rods are connected and move up and down when the engine lever is moved, it would appear that you have a failure in the lower unit or the engine drive shaft.

Sorry I forgot to say that there is no reverse gear either.

Spoken to Uncle Al and read all your posts and started to strip it down, disconnected the gear change rod at the joint at the back of the leg and moved the shift shaft up and down but prop still wonít engage.

The next thing I would guess is to drop the gear box and check the drive shaft?

i meant to tell you this morning drain the gear oil and look for metal particalls/filings if the oil comes out with lumps of metal game over.

Drained the oil and there was a few bits but my farther thinks that this would be normal???

Removed the gearbox and the drive shaft is ok, so it looks like the fault is in the gear housing?

The gear oil shouldn't contain any 'bits'.

You could pull the propeller shaft hub out to see what's been going on in there.

Then buy a good second hand lower unit, 'cos it will probably cost more than that to fix the original if 'bits' came out with the oil.

Depends how large they are.. because I have to say that in all my experience of draining hubs and gearboxes, its true to say I have seen more metallic oil contamination from outboard legs, which people suggest is normal which to me doesnt look like it should be. Perhaps its down to the metals used in the gears, but in any other environment if I see flakes, or grey or silvery oil, its a portent of something to come, and yet, the legs that I've seen it in, have run on and on

Obviously the situation here as outlined by the OP is different, as there is a failure involved, and I suspect that people with outboards in general do not change their gearbox oil often enough, because its a smelly dirty job, but by jingo its an important one, and not least of all because its submerged so much ,.. its an annual job IMO

Don’t worry about the bits, my father drained the gear box and we strained the oil through a cloth and the bits were nothing at all.

I have had a look again tonight and I think that it’s going into forward and reverse gears ok because I can feel the shift rod indexing the gears and I can hear the gears inside turning.

If I turn the drive shaft I can feel it sort of click into place at the same point in every revolution, so……

Could the drive shaft be snapped inside the gear box? Also how do I get it out?

Read JW's post again then,.. perhaps he's onto something but not just quite what you see ? could there be a shifter problem with the rods ?

I think itís going into gear fine and since draining the oil I can hear the gears turning so I think the shaft is snapped inside the gearbox. I canít strip it down any further without specialist tools so as Downhilldai said the best thing is to replace the gearbox. I have found a brand new one on ebay for £299 ouch! But probably worth it?
