I need a header exhaust pipe etc. for a Petter AC1W Marine Diesel that was purchased in 1987 in the USA for a Tidewater Annapolis 26 sailboat. Do you have the correct part number for ordering same and have this in stock? Thank you.

Hi,
I have recently fitted a new cylinder head to my 8 hp Sabb engine, I was told that the torque for the cylinder head bolts were 100ft/lbs by GEMS, yet your manual say 79 ft/lbs, that is quite a difference. Which is the correct value?
Also when I fitted the injector back does it have a copper washer both in the recess and where it fits on the cylinder head.
Last but not least I have the old style silencer, which will be in its final year and I intend to change out and go to a freshwater cooled system. However I was thinking of making a stainless steel silencer with seawater injection approx 2-3″ below the exhaust outlet, has anyone made this type. I believe the later version you sell also has a freshwater tank with it.
Regards
Don

Hello Don
I have emailed you a few attachments from the engine manual (I am unable to upload files on the blog, I don’t think!)
Attachment 1 shows the torque and injector set up ( one washer under the nozzle)
I am interested to find out which book you found the 79 ft/lbs as you can see the one I have here is clearly 100.
I have also attached some information on the fresh and salt water cooling systems available via Sabb – I am unable to comment on any ‘retrofit’ system as I am not a qualified engineer but I am sure someone with that experience will be able to assist with this.
You could also check out our web site from http://www.sleeman-hawken.co.uk/suppliers/sabb.html in the Sabb section you will find numerous service and maintenance tips for your engine.
If anyone else would like these attachments, just reply on here and I will email them to you.
Regards
Keith.

Hi,
Thanks, I believe I might have misread and was looking at the torque for the Sabb 2h see copy from your service PDF.
!Check head surface for flatness, machining if necessary. Clean out water passages, particularly holes between
cylinder block to head and between head to silencer.
Cylinder head nuts should be pulled down to 79 ft.lbs (11kpm). Tappet adjustment is 12 thou (0.3mm). Don’t over
tighten the locknut as the screws are quite brittle. Finally we strongly recommend that the head is pulled down again
whilst hot after the first run, even though this means removing the rocker gear again. Don’t be tempted to overtorque
the nuts initially or you may strip the threads!

Hi Keith. I have a SABB 18hp with vpp. It has done approx 1100 hrs and always serviced. Starts first time every time, idles happily at 450 rpm. Good oil pressure and operating temp. Prop has just been cleaned while on the hard for anti-fooling.
The problem is that as soon as I lift revs past 1250 rpm approx it starts to belch thick black smoke and unburnt fuel. Before I begin the hunt for a mechanic who has even heard of SABB do you have any clues for me as to what I can eliminate? Any advice greatly appreciated. I’m in Australia so the SABB with vpp attracts many comments and questions! Cheers Lindsay

Hi Lindsay,
Apologies for the delay in getting back to you.
I would check the injector and fuel pump first to check they are functioning ok, I suspect one of them or both are malfunctioning, have you had any bad fuel?
Is your fuel filter clean?
Regards,
Keith

Hi Keith, I’ve sent an email with pictures to your ‘sales’ address. the issue was a well and truly blocked manifold and as you can see I need another…desperately as it fractured during removal.
Cheers,
Lindsay

Hello Keith
my sabb gg 10 hp has been emitting black smoke at high RPGs ever since I replaced fuel line. Since then I had the fuel injector and pump rebuilt/serviced.
Still black smoke and water emitting. Any suggestions highly appreciated

Like one of the other posters, I have an old petter diesel in an Annapolis 26. Mine is a 1976. I just got the boat and I don’t know the engine model. Do you have any info on the model used in 1976? If so, do you sell manuals?
Thanks,
Dan

Hi Dan
I’m afraid its not enough to go off the year alone as many engines were being made at that time.
There should be an identification plate on the engine or some numbers in the crankcase… some photos would help?
If you could email anything to sales@sleeman-hawken.co.uk we can take a look for you.
Kind regards

Hello, I wonder if you have any experience repairing cracked cylinder heads? I have a Sabb 2h it was running reasonably well but one cylinder was showing signs of water ingress. I assumed head gasket but while re grinding the valves we found a crack. It was well hidden under a layer of scaley rust I know you could get me a new head but at £2000 its more than the boat is worth!

A good marine engineer will have access to a company that may be able to weld the crack you mention. Cracked cylinder heads are not unusual on water cooled marine engines. The specialist company will usually need to inspect the head to assess the crack as repair is not always possible.

Hi Keith, an update. I took the head to a few welders no one wanted or could do it. the required technique is submerged Arc. very specialised therefore expensive and to be able to subsequently cut a valve seat into is and guarantee the work near to impossible.
And so to Ebay I found a head in Germany in near perfect condition.
I reassembled the engine with a self cnc cut copper head gasket sealed with gaskacinch. its done a whole season 70 hours so far.
At he same time I also found a crack in the exhaust which actually welded up very easily with a mig welder. That has also survived 70 hours so far.

Kind regards

Good morning Bjorn.
Can you clarify what you mean by ‘engine top’?
Do you require a Cylinder Head? Or Rocker Cover?
If you could also provide your Sabb engine model, we can send some pages from a parts manual so that we can correctly identify your requirements.
Many thanks
