Thanks John.  It is making more sense to replace the entire unit.  I appreciate your getting back to me.

Bob,

I have a maramu with a Perkins M60 and have also looked at repowering as I have recently bought a new engine for another boat.

I installed a 75 hp yanmar in my non-amel boat and for various reasons kept the old gear box. The engine and box both had SAE4 bell housings so I thought it would be straight forward. However the shaft out the PRM260D box was too long and the damper plate I got didn't match up. After the expense of fabricating a spacer and machining the damper plate all is good but the moral of the story is next time I will get the engine with a gear box already attached. I don't think you can get a yanmar of the shelf with a ZF25 (new version of HBW250) but you can get a ZF30 with 2.7 ratio off the shelf. The ZF30 is similar but rated to a higher HP than the ZF25.

Unless your old gearbox is free of corrosion and is quite new I would recommend renew and try to sell the old one with the old engine. If you get a Cummins or other you should be able to get a suitable vertical offset gearbox such as a ZF25 ZF25H or ZF30.

Re: [Amel] Maramu engine replacement

Thanks Eric.  This is great information.   The dealer is saying that the 54 hp engine is also a good match for replacing the 60 hp Perkins I know have.  I don't know if this is true or not. The zf 30 is very close to the ZF 25    and Hp rating so I'm leaning toward buying a complete engine/trans package which will give me a 5 year warrenty on both units.  The 54 hp unit if more readily available which is why I'm considering it. 



Does anyone have a thought on installing a 54 hp Yanmar in at Maramu? 



Thanks to everyone who has replied/commented on my inquiry.

Bob, I replaced my motor with the Yanmar 4JH4, and used my original
transmission, which I think is the same as yours. I had my transmission rebuilt
as needed by a local shop. I was going to get a new trans, but ZF (who bought
out Hurth) was back ordered 6 months. It ended up that by using my old trans the
installation was a lot easier. First you can use your old rear motor mounts. The
Hurth trans bolts up to an adapter plate, that will bolt directly on the Yanmar.
The rear motor mounts are mounted to this adapter plate. The Yanmar supplied
rear mounts are bolted to the engine. The Yanmar engine mounts are on 18 inch
centers, whereas the engine beds and your old mounts are on 22 1/2 inch centers.
By using your old trans and adapter plate you eliminate a lot of alignment
issues. It may be that the ZF gearbox will mount on this adapter plate, and you
could do the same thing, but I don't know. When I installed my engine, I was
able to use new rubber engine mounts (not the Yanmar, they are to tall) and the
rear mounts lined up exactly with the original Amel mounting bolts. On the front
mounts I bolted a 1/2 steel plate on the original engine bed, using the original
Amel mounting bolts, to bring it in to the 18 inch centers required for the
Yanmar engine mount alignment. The other advantage to using the original
trans is I was able to keep my shaft mounted alternator, without having to
fabricate a new mount.  If you go with a new trans, I would not go with any down
angle, as you will have to do considerable modification to the engine beds. The
front of the engine will have to be dropped about 6 inches, and you will
therefore have to remove that much of you engine beds I believe. The engine beds
have steel plates embedded in them into which the original motors mounts are
bolted. Very strong. I was able to reuse all of them. Handy. The only thing to
have to modify on the engine beds with the original trans, is the area around
the oil filter, which comes out of the right hand side, right at the level of
the top of the engine bed. You have to cut it out in a half moon shape about an
inch.

The engine swap was actually quite simple, and I can provide you with photos of
my install, if you go a similar route.

Eric, Maramu 105

Re: [Amel] Maramu engine replacement

Chris Smither <yachtakwaaba@...>
 

Graham,
    No, I did not do it myself - I had no repair manual, and I was told that the job is simpler with a couple of "special" tools that all ZF/Hurth agents have in their workshop.
   The symptoms that you notice are:- ( you can get some or all!!)

1. A longer than normal pause between selecting a gear and the drive engaging.
2. No reverse gear
3. Discoloured gearbox fluid - sometimes it smells "burnt"
4. A major leak from the oil seals.

The parts for the ZF25 are all included in what is called, I believe, a rebuild kit, which does not include a damper plate. 


On the Santorin, you have to remove the water and exhaust hoses at the front of the engine; "split" the drive train; remove the engine hold down bolts and slide the whole engine aft about 2-3". The gearbox can then be removed, and taken to a workshop.

If you have a ZF/Hurth agent near you they should have all the tools, and the manuals. However, there are plenty in Europe, so if you don't have a problem, and all is working well.......

What I would do is check the fluid in the gearbox by pumping it out into a clear container and then looking carefully for any specks of "dark matter" or cloudiness. If either is there, then I would get the gearbox off and get it rebuilt.

Hope this helps

Mike

BATTERY CHARGERS

WilliamR <leonorebt@...>
 

THIS IS BILL ON LEONORE OF SARK SM72. I READ WHERE SEVERAL FOLKS WERE HAVING TROUBLE WITH HIGH AMPERAGE BATTERY CHARGERS WHEN AT THE DOCK WITH REDUCED POWER AVAILABLE.
MY SOLUTION IS THE MASTERVOLT CHARGER WHICH IS A WONDERFUL UNIT. IT HAS THE STANDARD VOLTAGE SETTINGS FOR BULK, ABSORPTION AND FLOAT PHASES OF 28.8, 28.5 AND 26.5V. MINE IS 80A 24V UNIT.
THE BEAUTY IS THAT THE VOLTAGES ARE PROGRAMABLE SO THAT IF AT THE DOCK YOU CAN SET THE BULK VOLTAGE TO SAY 26.5 SO THE AMPS ARE REDUCED DRAMATICALLY AND YOU DO NOT OVERLOAD ANYTHING. YOU CAN EXPERIMENT WITH DIFFERENT VOLTAGES TO SUIT YOUR OWN NEEDS. BUT USUALLY ONCE YOU GET BY THE BULK PHASE THE AMP DRAW IS DOWN SIGNIFICANTLY FOR THE ABSORPTION AND FLOAT STAGES.
THIS ELIMINATES THE NEED FOR TWO CHARGERS!

ANOTHER WONDERFUL ASPECT OF THE MASTERVOLT IS THAT AFTER THE BATTERIES ARE FULLY CHARGED AND YOU DECIDE YOU NEED TO EQUALIZE, YOU CAN RUN UP THE FLOAT VOLTAGE TO SAY 28 OR 30 VOLTS AND IN ESSENSE HAVE AN EQUALIZE FUNCTION WITHOUT ATTEMPTING TO TRIGGER THEIR DIP SWITCH FOR THAT PURPOSE WHICH IS DIFFICULT TO REACH. CAUTION! YOU MUST MANUALLY RESET THE FLOAT VOLTAGE AFTER YOU HAVE EQUALIZED AS DETERMINED BY HYDROMETER READINGS. FAILURE TO DO SO WILL COOK YOUR BATTERIES AS THERE IS NO TIME OUT AS THERE IS WITH A TRUE EQUALIZE.

I HAVE FOUND THE FLEXIBILITY TO BE MUCH APPRECIATED.

BY THE WAY, AFTER MANY YEARS SAILING, LEONORE IS FOR SALE. SEE HER WEB SITE: WWW.AMELYACHT.COM

Bob,
I successfully replaced my Perkins with a Westerbeke 85B several years ago
and used the standard Hurth transmission that came with it. At that time my
Perkins was overheating and I wanted to use a naturally aspirated diesel
engine for greater reliability.

old one? If you purchases a new one, which model did you purchase. My
concern at this point is that the dealer I'm working with shows transmissions
that have a 7 degree down angle and the one I have has an offset rather then a
down angle.

Has anyone used the 75 hp Volvo instead of the Yanmar. Is there an
advandage/disadvantage either way?

Thanks for any advise you can provide.

Bob, I replaced my motor with the Yanmar 4JH4, and used my original
transmission, which I think is the same as yours. I had my transmission rebuilt
as needed by a local shop. I was going to get a new trans, but ZF (who bought
out Hurth) was back ordered 6 months. It ended up that by using my old trans the
installation was a lot easier. First you can use your old rear motor mounts. The
Hurth trans bolts up to an adapter plate, that will bolt directly on the Yanmar.
The rear motor mounts are mounted to this adapter plate. The Yanmar supplied
rear mounts are bolted to the engine. The Yanmar engine mounts are on 18 inch
centers, whereas the engine beds and your old mounts are on 22 1/2 inch centers.
By using your old trans and adapter plate you eliminate a lot of alignment
issues. It may be that the ZF gearbox will mount on this adapter plate, and you
could do the same thing, but I don't know. When I installed my engine, I was
able to use new rubber engine mounts (not the Yanmar, they are to tall) and the
rear mounts lined up exactly with the original Amel mounting bolts. On the front
mounts I bolted a 1/2 steel plate on the original engine bed, using the original
Amel mounting bolts, to bring it in to the 18 inch centers required for the
Yanmar engine mount alignment. The other advantage to using the original
trans is I was able to keep my shaft mounted alternator, without having to
fabricate a new mount. If you go with a new trans, I would not go with any down
angle, as you will have to do considerable modification to the engine beds. The
front of the engine will have to be dropped about 6 inches, and you will
therefore have to remove that much of you engine beds I believe. The engine beds
have steel plates embedded in them into which the original motors mounts are
bolted. Very strong. I was able to reuse all of them. Handy. The only thing to
have to modify on the engine beds with the original trans, is the area around
the oil filter, which comes out of the right hand side, right at the level of
the top of the engine bed. You have to cut it out in a half moon shape about an
inch.

The engine swap was actually quite simple, and I can provide you with photos of
my install, if you go a similar route.

Eric, Maramu 105

Bob,

I have a maramu with a Perkins M60 and have also looked at repowering as I have recently bought a new engine for another boat.

I installed a 75 hp yanmar in my non-amel boat and for various reasons kept the old gear box. The engine and box both had SAE4 bell housings so I thought it would be straight forward. However the shaft out the PRM260D box was too long and the damper plate I got didn't match up. After the expense of fabricating a spacer and machining the damper plate all is good but the moral of the story is next time I will get the engine with a gear box already attached. I don't think you can get a yanmar of the shelf with a ZF25 (new version of HBW250) but you can get a ZF30 with 2.7 ratio off the shelf. The ZF30 is similar but rated to a higher HP than the ZF25.

Unless your old gearbox is free of corrosion and is quite new I would recommend renew and try to sell the old one with the old engine. If you get a Cummins or other you should be able to get a suitable vertical offset gearbox such as a ZF25 ZF25H or ZF30.
