Thanks everyone for their input. Just an update for future reference of the group.

Without the tool, I couldn't remove the shaft. So I went back in the water and used the hacksaw per Craig's idea. I sawed across boltholes until eventually the remains of the prop and the hub came off (being careful as Bill of BeBe reminded me). Then I cut a slot in each of the mangled bolts that were left and unscrewed them. (Sidenote - one of the screws that was left intact was the metal alignment screw. Someone had obviously left this in and didn't replace it with the nylon screw. Leaves me to believe that this might have been the source of why the prop/screws didn't come off like they are supposed to). Last, I locked Vicegrip pliers on one end of the thrupin. Then using a punch, I hammered the other end until it came out. This took a while and when it was finally came out, it was bent.

After that, the installation of the new hub, pin and prop was very straightforward.

Special thanks to Mark and Cindy aboard Cream Puff here in Green Turtle Cay for their guidance along the way.

Now, back to the martinis!

Hi Gary,
thanks for all the good news.
To be sure staying on a safe side, I unfortunately resigned my registration this morning. I will resubmit a new one by now.
I am volunteering to help you for the transfer of the current data, as you may have seen in a precedent post.
If you agree we can use the new forum functionalities to discuss how to make it happen.
I am in the same conditions you are with regard to internet access. It can lead to small interrruptions in our communication.
Cheers

Alex,

Here's my take on low rpm. This is a chronic problem for many SMs powered with ~75HP engines.

After I spent thousands of $ on mechanics, new turbo, testing fuel pump and injectors, compression check, timing checked (the only thing I didn't do was service the AutoProp)...., I got the serial number off of the Autoprop and called Bruntons. They said it was the prop they recommend for the SM with a 100HP Yanmar.

A good prop shop in Norfolk tested my spare fixed prop and said it was also over sized and over pitched for my boat with 78 HP Volvo.

With maximum rpm of 2400...

Try putting your spare fixed prop on and see what you get. If still inadequate rpm, have the spare prop size/pitch tested and compared against what is calculated/recommended for your boat/engine.

If there's nothing wrong with the engine, the bottom and prop are clean, and the prop has been recently serviced, there is likely to be a buildup of carbon in your turbo that needs to be addressed. (Removed and cleaned regularly.) If it is left unaddressed, it will eventually need to be replaced, at significant cost.

If all indications are that you are over-propped, consider trying a prop that is pitched for your boat/load/engine per calculations by a good prop shop. When I had the same problem with my 78hp Volvo, I finally had my spare fixed prop repitched, and got 3200 rpm under load.

I know many Amel owners are skeptical about this, believing that there is still something else going on that is responsible for your low rpm. I'm convinced that my original AutoProp and spare fixed prop were not matched to my boat with 78HP Volvo TMD22. It resulted in replacing the turbo twice in less than 5000 engine hours, and may have been a contributing factor in the eventual cracked block that killed the engine for good.

I still have the spare prop that was cut down and repitched according to prop shop calculations if you would like to try it. I'd be happy to let you borrow it if we can find a time/place to do it. It is now under propped for my new 110HO Yanmar, so if you (or anyone else) wants to buy it at a good price, I'll be happy to ship it to you.

Steady as she goes,

Kent

Hello Eric

No, no, I wish.
2400 rpm is the maximum ( auto prop rebuild and recent antifouling).

The specification of the Volvo TMD 22 P says 78 HP at 4500 rpm.
I can post the info if interested.

2000    My boat was definitely fully
loaded too...

If you look
at the specs, the Volvo TMS 22 P is rated for 78 HP, but
only if you reach 4500 rpm... which we can't....
So at 1500 rpm it is about 30 HP, at 1800 rpm
40 hp.

I bought my
boat several months

ago.
Boat was made in 2002, she has 75 HP Yanmar engine.

I decide to establish my boat performance
characteristic.
I

tested boat speed at three different engine
RPM. My test

results are as
follows:

Engine
RPM           Boat speed in

KN

1500.

4.7

2000.

6.3

2500.

7.5

Boat speed test minimised current or wind

effects. The speed was taking
from GPS at maximum stable

speed.

I wonder if those results are
as good as expected or not.
Do

we have any similar data from
Amel?

Vladimir,

I would say that the speed looks about right for an AutoProp.

Boat speed test minimised current or wind effects. The speed was taking from GPS at maximum stable speed.
I wonder if those results are as good as expected or not. Do we have any similar data from Amel?

2000    Hello Eric

No, no, I wish.
2400 rpm is the maximum ( auto prop rebuild and
recent antifouling).

The
specification of the Volvo TMD 22 P says 78 HP at 4500 rpm.

I can post the info if interested.

2000    My boat was definitely fully
loaded too...

If you look
at the specs, the
Volvo TMS 22 P is rated for 78 HP, but
only
if you reach 4500 rpm... which we can't....
So at 1500 rpm it is about 30 HP, at 1800
rpm
40 hp.

Sincerely,
Alexandre

I bought my
boat several
months

ago.
Boat was made in 2002, she has 75 HP Yanmar
engine.

I decide to establish my boat
performance
characteristic.
I

tested boat
speed at three different engine
RPM. My
test

results are as
follows:

Engine
RPM
Boat speed in

KN

1500.

4.7

2000.

6.3

2500.         

7.5

Boat speed test minimised current or wind

effects. The speed was
taking
from GPS at maximum stable

speed.

I wonder if
those results are
as good as expected or
not.
Do

we
have any similar data from
Amel?

 2000    Hello Eric

 No, no, I wish.
 2400 rpm is the maximum ( auto prop rebuild and
 recent antifouling).

 The
 specification of the Volvo TMD 22 P says 78 HP at 4500 rpm.

 I can post the info if interested.

 2000    My boat was definitely fully
 loaded too...

 If you look
 at the specs, the
 Volvo TMS 22 P is rated for 78 HP, but
 only
 if you reach 4500 rpm... which we can't....
 So at 1500 rpm it is about 30 HP, at 1800
 rpm
 40 hp.

 Alexandre

 Engine RPM vs Boat speed for
 Amel-Super-Maramu 2000

 To: amelyachtowners@yahoogroups.com

 Date: Wednesday, January 6,
 2016, 5:29 AM

 I bought my
 boat several
 months

 ago.
 Boat was made in 2002, she has 75 HP Yanmar
 engine.

 I decide to establish my boat
 performance
 characteristic.
 I

 tested boat
 speed at three different engine
 RPM. My
 test

 results are as
 follows:

 Engine
 RPM          
 Boat speed in

 KN

 1500.                                 

 4.7

 2000.                                 

 6.3

 2500.                                 

 7.5

 Boat speed test minimised current or wind

 effects. The speed was
 taking
 from GPS at maximum stable

 speed.

 I wonder if
 those results are
 as good as expected or
 not.
 Do

 we
 have any similar data from
 Amel?

Hi Alexandre ,

I saw that and thought you purchased the very optional Jet Pack.

Hello Eric

No, no, I wish.
2400 rpm is the maximum ( auto prop rebuild and recent antifouling).

The specification of the Volvo TMD 22 P says 78 HP at 4500 rpm.
I can post the info if interested.

2000    My boat was definitely fully
loaded too...

If you look
at the specs, the Volvo TMS 22 P is rated for 78 HP, but
only if you reach 4500 rpm... which we can't....
So at 1500 rpm it is about 30 HP, at 1800 rpm
40 hp.

Sincerely,
Alexandre

I bought my
boat several months

ago.
Boat was made in 2002, she has 75 HP Yanmar engine.

I decide to establish my boat performance
characteristic.
I

tested boat speed at three different engine
RPM. My test

results are as
follows:

Engine
RPM           Boat speed in

KN

1500.

4.7

2000.

6.3

2500.

7.5

Boat speed test minimised current or wind

effects. The speed was taking
from GPS at maximum stable

speed.

I wonder if those results are
as good as expected or not.
Do

we have any similar data from
Amel?

Re: [Amel Yacht Owners] Engine RPM vs Boat speed for Amel-Super-Maramu 2000

Hello Eric

No, no, I wish.
2400 rpm is the maximum ( auto prop rebuild and recent antifouling).

The specification of the Volvo TMD 22 P says 78 HP at 4500 rpm.
I can post the info if interested.

 If you look
 at the specs, the Volvo TMS 22 P is rated for 78 HP, but
 only if you reach 4500 rpm... which we can't....
 So at 1500 rpm it is about 30 HP, at 1800 rpm
 40 hp.

 Sincerely,
 Alexandre

 I bought my
 boat several months

 ago.
 Boat was made in 2002, she has 75 HP Yanmar engine.

 I decide to establish my boat performance
 characteristic.
 I

 tested boat speed at three different engine
 RPM. My test

 results are as
 follows:

 Engine
 RPM           Boat speed in

 KN

 1500.                                 

 4.7

 2000.                                 

 6.3

 2500.                                 

 7.5

 Boat speed test minimised current or wind

 effects. The speed was taking
 from GPS at maximum stable

 speed.

 I wonder if those results are
 as good as expected or not.
 Do

 we have any similar data from
 Amel?

Vladimir, how many RPM will your engine develop at maximum and what speed does the boat achieve? What propellor are you using?

To: amelyachtowners@...

I bought my boat several months
ago. Boat was made in 2002, she has 75 HP Yanmar engine.

I decide to establish my boat performance characteristic. I
tested boat speed at three different engine RPM. My test
results are as follows:
Engine RPM           Boat speed in
KN

1500.
4.7

2000.
6.3

2500.
7.5
Boat speed test minimised current or wind
effects. The speed was taking from GPS at maximum stable
speed.

I wonder if those results are as good as expected or not. Do
we have any similar data from Amel?

Hi Bill next you haul out to do the bottom get the old toilet you never use any way and do a good job of cleaning the intake line to the sea chest. Then while painting the bottom take a the rag you wipe out the can with on a stick and paint the in take. Do the same with the other salt water intakes. But use a bottle cleaner brush.

Smooth sailing. We are back in Newport.

Thanks for all the suggestions!!! Just to be clear, there is minimum to no growth in the sea chest itself. The growth (and blockage) is below the seacock. When I do clean this I have to open the seacock and scrub below the ball valve to open it up. After it opens up seawater refills the sea chest and I have to shut it off to avoid overflow when it is unclogged and the cover is removed. Now, I know why the previous owner kept a toilet brush in the engine room.

Just a quick question, is it okay to run the engine while the cover is off the sea chest while I am trying to run BB through the raw water systems?

Thanks,

My boat was definitely fully loaded too...

If you look at the specs, the Volvo TMS 22 P is rated for 78 HP, but only if you reach 4500 rpm... which we can't....
So at 1500 rpm it is about 30 HP, at 1800 rpm 40 hp.

Sincerely, Alexandre

I bought my boat several months

ago. Boat was made in 2002, she has 75 HP Yanmar engine.

I decide to establish my boat performance characteristic.
I

tested boat speed at three different engine RPM. My test

results are as follows:

Engine RPM           Boat speed in

KN

1500.

4.7

2000.

6.3

2500.

7.5

Boat speed test minimised current or wind

effects. The speed was taking from GPS at maximum stable

speed.

I wonder if those results are as good as expected or not.
Do

we have any similar data from Amel?

Re: [Amel Yacht Owners] Engine RPM vs Boat speed for Amel-Super-Maramu 2000

Alexandre Uster von Baar

My boat was definitely fully loaded too...

If you look at the specs, the Volvo TMS 22 P is rated for 78 HP, but only if you reach 4500 rpm...  which we can't....
So at 1500 rpm it is about 30 HP, at 1800 rpm 40 hp.

Sincerely, Alexandre

       How many HP in your engine?

 My boat was fully loaded.

       Good morning Vladimir,

 My speeds were similar, using the Volvo TMD 22.

 1400 rpm 4.5 kt

 1600 rpm: 5 kt

 1800 rpm 5.5 kt

        I bought my boat several months

  ago. Boat was made in 2002, she has 75 HP Yanmar engine.

  I decide to establish my boat performance characteristic.
 I

  tested boat speed at three different engine RPM. My test

  results are as follows:

  Engine RPM           Boat speed in

  KN

  1500.                                 

  4.7

  2000.                                 

  6.3

  2500.                                 

  7.5

  Boat speed test minimised current or wind

  effects. The speed was taking from GPS at maximum stable

  speed.

  I wonder if those results are as good as expected or not.
 Do

  we have any similar data from Amel?

How many HP in your engine?
My boat was fully loaded.

I bought my boat several months
ago. Boat was made in 2002, she has 75 HP Yanmar engine.

I decide to establish my boat performance characteristic. I
tested boat speed at three different engine RPM. My test
results are as follows:
Engine RPM           Boat speed in
KN

1500.
4.7

2000.
6.3

2500.
7.5
Boat speed test minimised current or wind
effects. The speed was taking from GPS at maximum stable
speed.

I wonder if those results are as good as expected or not. Do
we have any similar data from Amel?

Engine RPM vs Boat speed for Amel-Super-Maramu 2000

VLADIMIR SONSEV

#24666

I bought my boat several months ago. Boat was made in 2002, she has 75 HP Yanmar engine.
I decide to establish my boat performance characteristic. I tested boat speed at three different engine RPM. My test results are as follows:

Engine RPM           Boat speed in KN
1500.                                  4.7
2000.                                  6.3
2500.                                  7.5

Boat speed test minimised current or wind effects. The speed was taking from GPS at maximum stable speed.
I wonder if those results are as good as expected or not. Do we have any similar data from Amel?
