Excellent and very helpful advice everyone. Very much appreciated.
This week a prop switch-out back to the original and a retest.
Servicing of the auto-prop for sure.
We will see what happens!

Thank you Bill, Oliver, Alexandre,Eric, Drew and all the others.

What a resource.

Hello Porter,

as Mark says, you should be able to turn the blades with one finger. If not, the blades cannot take the same pitch and overload the engine.
This is a problem with the ball bearings of the blades. These are watertight ball bearings with steel balls (unlike the first generation of AUTOPROPS with open bearings and stainless steel balls). They need to be greased every time the boat is hauled out and at least once a year. These ones may not be watertight anymore, and the balls got rusty. They will probably need replacement. Did someone try to grease the bearings before launching?
The second problem was that the blades were fouled, and from what I see, the fouling may take off 20% of the engine's power (even with new bearings). I guess the prop is now clean!!

So, don't touch the engine until you have an AUTOPROP in working order. You could make the engine tests with the fixed prop that is originally supplied with the 54, as I guess the sellers will not be able to get new bearings and replace them quickly.

Have a nice day.

Olivier

The rebuild of the prop is simple, it just takes time. You can do it yourself.

I totally agree with Bill

6 months ago, my Auto prop was dirty (not as bas as the one on the video) and I had lot of black smoke and couldn't exceed 1350 rpm...
I scuba dive, cleaned it, then was back to 2400 rpm.

Since you already put out money for trip, haul out, etc. have the current owner have the propeller "properly" rebuilt (had mine 2 years ago) then go again for a test.
May be you split the cost. If it solves the problem, like I think it will do, then good. But should the engine still smoke, then i would pass...

Porter that prop is fouled
enough to be the source of all of your issues.
I cannot guarantee that it is 100%
of the source, but probably is.

Porter,
I am
really very surprised that Dave Huffman, the broker, the
Volvo mechanics, and Nigel Calder never asked if the
propellor was clean. The number one cause of the symptoms
you mentioned is an overloaded diesel engine. The number one
cause of an overloaded diesel on an Amel with an AutoProp is
growth on the blades...even a small amount of growth. Growth
causes the blades to pitch too much, biting too much water
and overloads the engine.
Also, from my experience, people
like Nigel Calder who make imperative and absolute
statements like "...should never smoke
and is indicative of a serious issue,"
are only correct the majority of the time and usually
provide good advice for gamblers. I hate
gambling.
So, I
will ask you: Is the propellor clean?
The other thing that I sometimes
hear from experts is that the H6 AutoProp is too large or
too small. Evidence that it is correct for a SM and a 54 is
that over 600 Amels are operating with them...I believe that
fact is much more credible than anyone's
opinion.
Lastly, some
of the Volvo D-3 110 have issues that sometimes even experts
cannot figure out. If you own a good one, you will love
it...if you own a bad one, good luck. That said, the chances
of that Volvo being a good one are very high because based
on the hull number, that engine was probably made in
Volvo's 4th-5th year of production of the D3
110.
My advice,
thoroughly clean that propellor and try things
again.
Best,

Porter, I’m not sure
why you would trust the opinion of a group member rather
than your own instincts and opinions of the expert
mechanics? You seem convinced the boat has an issue and I
seriously doubt even the most knowledgeable members of this
group can guide or are willing to guide you down a
particular path. If
this is the boat for you, then reach a deal with the owner.
Or, cut your losses and look for another
boat. With best
