I do not recall seeing a coupling,

However, you might ask other owners with a yanmar to look at their engine as
I am in NY and the boat is in SXM

Hi Eric, does the Yanmar instalation have a coupler like the Vetus (or any
coupling) between the gearbox and the C drive? If so all I said would be
pertinent as the Amel with the Yanmar has the angle iron rails for the
engine to sit on.
Simply undo that coupling and proceed. The cabling, gearbox controls etc may
be different but detaching them is just a matter of care and observation.
Removal of the gearbox from the rear of the engine (or front if you look at
the orientation in the boat) is unlikley to be much different.

Danny,

That serial number Amel Super Maramu #435 probably has a Yanmar
engine as does mine.

Hi Trevor,
I have done this and it would be the easiest boat in the world to work on in
this area.
Ours is SM 299 with the ZF (or Hurth as they used to be) and a Volvo TMD22.
There is a Vetus connector between the gearbox and the C drive.
Undo the four bolts holding this together. To move the motor forward prepare
by removing the cables to the gearshift.. You may have to remove the
flexible exhaust connection from the motor, in ours I didn't, there was
enough movement available.
Remove the water pipes to the oil cooler (both in and out) first turning off
the sea cock..
Check all cables and fuel lines to the motor, we did not have to remove any,
you may.
As you shift the motor watch carefully that nothing is pulling up short or
snagging.
You only need to move the motor around 150mm (six inches).
Now undo the 4 large bolts securing the motor to the angle iron engine
beds. Take the bolts out. Now the engine is ready to be slid forward.
I do this by using a piece of 75 x 50mm (2" x 3") timber as a lever. (this
is what make the Amel so easy, most boats you have to take the engine off
the engine mounts and physically lift it to move it.)
Slide it a little at a time ensuring the the bolts through the vetus slide
free. If you cannot remove the nuts on these before you move the motor (no
room for the nut to come off) just move the motor a little then take the
nuts off.
Once the motor is moved you have 6 ( I think) nuts to remove on the back of
the motor that hold a dish shaped housing on to the motor to which the gear
box is fixed. Undo these and you can lift the gear box off along with the
dish shaped housing.

There is a spline into what looks like a car clutch plate that is bolted to
the flywheel of the engine into which the gearbox shaft enters. There are a
series of springs in this for shock absorbsion. If they have never been
replaced it may be a good idea to do this while the gear box is off. If you
don't do this there is no need to take this plate off the fly wheel.
Likewise there are 4 rubber bushes in the Vetus connector with a dual role,
correcting (very) minor alignment issues and providing shock absorbsion.
Hope this helps. I reiterate, it is the easiest boat you will ever find if
you have to move the motor.
Regards

Dear All,does anyone know the correct sequence and procedure of where and
how to split the drive train between my ZF 25 and the C drive to allow me to
remove and replace the gearbox.The boat is in the water and it appears that
either the engine has to move forwards or the top part of the Cdrive needs
to de dismantled? Neither option is attractive.Any advice would be very much
appreciated.Thank you very much.Trevor LustySeafever of CuanSupermaramu no
