Hope you have finally bottomed out the problem mate and she goes for years now
Since refitting my new ZF 10 box the boat is fine and all appears well, but I have noticed a reduction in speed, I have to add about another 200 rpm
to achieve the same knots as before.
My props is 15" and the engine a 27.5 hp, but I do have a longer shaft than you had, I guess about 2'.
The R&D drive/thruster plate is also new and replaced the existing unit.
By the way does yours go in with a 'clunk' when you go into gear?
Talking to people with the same box it seems the secret to long life is mainternace of the gearbox
like changing the ATF often, I will change mine at the 60 hrs recommended and every 100 hrs there after.
