Thanks, Duane,


I find the easiest way to change an impeller on the Onan is to detach the two water pipes, undo the two bolts holding the pump to the engine and then you can fit a new impeller in the comfort of your cockpit.


The first time that you remove the pump you may have to give it a sharp tap to disengage. Thereafter it's simple. 


My impellers last about 200 hours. The sensor is not that sensitive--when it cut out the engine yesterday the impeller had ONE blade on it. The rest were blocking the heat exchanger.

I put a PDF in the Files section under Onan Information.

The PDF is a set of photos of my overhaul of the water pump.  With the Bearing Puller I have (bought from Harbor Freight) it really wasn't too bad or complicated of a job.  I had the "Major Service Kit" from Onan on board and it had some pretty good instructions.  

The intent of the PDF is to just give a visual overview of the process and how it can be accomplished with a bearing puller in lieu of a hydraulic press.  It's worth noting that the instructions from Onan, under Tools required, lists a "Hand Press".  I expect they are referring to something like my bearing puller.

Have fun!

On the Krow, no problems.

Duane Siegfri
 

We met a couple in Beaufort, NC who owned an Amel SM (I think it was a 2003) named Krow.  I can't remember his name, but her name was Jane.  They must be in their 70's.


I thought it was worth posting here that they bought it used and sailed the Caribbean, and then the Med, and told me that nothing ever broke down on the boat.  It was perfect.  I have to note here, that they have already sold the boat...


It reminds me of the old joke that, among sailors, there are "them that have run aground, and the damn liars!".  Now, I'm not calling their assertion into question, I just envy their experience.


Best regards to all the mechanics out there,

In short. Seems like diesels (or the industry and associated standards) took a step back in the past 15 years putting efficiency over simplicity. I think Nigel Calder would agree.

Porter,

 

It really doesn’t matter how you do it but you need to create internal engine heat to clean out the engine. This is done with a load on the engine. If in neutral, it will take longer to create a load and heat. In gear while underway will heat up the engine faster.

 

This is true for all diesel engines.

 

Where you run the RPM depends on the engine. Typically, 80% of max power will heat up the engine nicely without too much strain. This is also good for the turbocharger, if fitted with one.

 

How long? At least every couple of hours while underway, if not a little more frequently... We run ours up every hour for about five minutes. This works for us.

 

Keep in mind, this is not just the ship’s engine but also true for the genset. Running a genset without load will cause carbon buildup. Keep the genset loaded when charging batteries etc. We find it best to run a couple of AC units or do a load of laundry etc. The battery charger only puts load on the genset at the beginning of the charge cycle.

 

Hope this helps.

 

 

With best regards,

 

Mark

I do have a few real questions, that I’ve had for a while. 

It’s the same for all diesels. Yes?  

Is “racing” out of gear best?  I would think load would be required to increase fuel consumption and thus heat. Fuel burn>>heat dissipation 2/2 raw water flow. 

Forget the rpm. Where is the throttle?  100% down? 80%?  

And for how long?

Wow! Sorry. I didn’t realize I had to be so freaking specific. Seriously! The essence of the post I made is 100% correct. I didn’t intend to make a verbatim quote of the manual.

And, please note I did say 4JH4 manual, not 4JH3 as you are quoting.

 

But if you want specific details of the JH4 Operation Manual, publication number OAJH4-G00102, page 78. I quote, “Periodically operate the engine near maximum speed while underway. This will generate higher exhaust temperatures, which help clean out hard carbon deposits, maintain engine performance and prolong the life of the engine”

This is below the section you quote about running it in idle and speaks specifically about running the engine while underway.

 

Regardless of whether this is done in neutral or in gear while underway, the purpose of the procedure is to raise the internal temperature of the engine periodically to remove carbon build up. Carbon build up will kill a diesel engine.

 

I’m feelin’ a little crabby today. Can you tell?

Hi Mark,

Regarding "Running a lower RPMs without load will shorten the life of the engine unless it is pushed up at least once per hour for about 5 minutes. This is outlinede in the Yanmar operation manual."

 

This is not to challenge the veracity of your statement but I cannot find that in my Yanmar manual. Maybe you have a different manual and it would be helpful (really) to have you quote what it says. 

 

What my 4JH3-HTE Operation Manual says (on page 30 section 4.6) is: 

 

"When operating the engine at low speed ffor long periods of time, race the engine once every 2 hours"..."Racing the Engine, Morse Remote Control Handle Pull out the handle lever...and shift the engine speed from high to low several times...Racing the engine removes carbon built up in the compustion chamber around the fuel injection valve.  Neglecting to race tthe engine will cause the exhaust to turn black and lower the efficiency of the engine".

 

In other words it says to gun the engine several times while it is in neutral.

 

Like others, we vary my speed between 1600 and 2200 for cruising and can cruise up to 2400 rpm.  We also run it at say 2800 for 5 minutes or so periodically.  However, I cannot find where Yanmar recommends this.  There are postings in this group (not yours) that say to run it full out for 5 minutes, even full out fo 30 minutes but I don't think that is advisable. Seems that vibration is higher and it might be hard on the transmission and c drive as well.  Like most of us we vary the speed and run it harder at times but we also do the "Racing" procedure that is in our manual.

Re: [Amel Yacht Owners] Re: Freshwater Pump - pressure sensing mechanical switch

Colin - ex SV Island Pearl
 

Thank you Wolfgang, you are correct. Earlier on we had noticed that the pump never kept running when plugged into a marina shore power, as batteries always fully charged, but then started it's nonsense again every morning at anchor as the charge fell below 25.1 volts.

That was the first problem we had some 3 months before it got much worse.

We are sorted now, as a new pressure switch is being sent out by Amel (our one will be fixed and kept as a spare) and we have also a 2nd complete fresh water pump system which bypasses the original one (with it's own one way valve and pressure switch), and quick system change over taps to change over between the two separate systems. In this way we will be back in business tomorrow and can also go back to the original Amel system (and visa versa) when that new pressure switch part finally arrives from Amel.

Thanks to all for the suggestions and assistance. Also a special thanks to Bill Rouse for the huge amount of very informative fresh water pump setting information (10 pages) sent privately from his exceptional 400+ page Amel maintenance book. Whist I do not have a copy of Bill's complete book, from the 10 pages I have now seen, I would think his book should be the first resource any new (or existing) Amel owner should turn to, and keep handy on board.

I stumbled across this video yesterday.  Apparently Nikimat (2001 Super Maramu, Hull # 289) is going to be parted out to rebuild Agapanthe (Rafael's boat a 1999 Super Maramu, Hull #246).  Both were totalled in Hurricane Irma at St. Martin.  I only post this to show the toughness of these boats.  I know many of us wondered exactly what kind of damage it would take to sink a Super Maramu.  Despite severe damage and being nearly chopped in half,  Nikimat looks to be in remarkably good condition considering what she lived through in her final hours.  (I did check with Alexandre before posting this).  Despite everything he's gone through, he continues to be a leader in this great community, helping others.

Porter,

 

I think you need to look in the manual for the correct temperature range of the engine. It should give you a range in the specs section. You will want to run at the high end of the range for a few minutes.

 

My 4jh4 tops out at 87°C or about 190°F. At lower RPMs it runs just below 82°C or about 180°F

 

With best regards,

 

Mark

Thanks Mark. 

If temp is the final data point, we cruise at about 79-80. What should be the goal?

Thanks again!

Porter,

 

It really doesn’t matter how you do it but you need to create internal engine heat to clean out the engine. This is done with a load on the engine. If in neutral, it will take longer to create a load and heat. In gear while underway will heat up the engine faster.

 

This is true for all diesel engines.

 

Where you run the RPM depends on the engine. Typically, 80% of max power will heat up the engine nicely without too much strain. This is also good for the turbocharger, if fitted with one.

 

How long? At least every couple of hours while underway, if not a little more frequently... We run ours up every hour for about five minutes. This works for us.

 

Keep in mind, this is not just the ship’s engine but also true for the genset. Running a genset without load will cause carbon buildup. Keep the genset loaded when charging batteries etc. We find it best to run a couple of AC units or do a load of laundry etc. The battery charger only puts load on the genset at the beginning of the charge cycle.

 

Hope this helps.

 

 

With best regards,

 

Mark

Ok. Bullshit aside. 

I do have a few real questions, that I’ve had for a while. 

It’s the same for all diesels. Yes?  

Is “racing” out of gear best?  I would think load would be required to increase fuel consumption and thus heat. Fuel burn>>heat dissipation 2/2 raw water flow. 

Forget the rpm. Where is the throttle?  100% down? 80%?  

And for how long?  

 

Many thanks, as always to this great group.

Wow! Sorry. I didn’t realize I had to be so freaking specific. Seriously! The essence of the post I made is 100% correct. I didn’t intend to make a verbatim quote of the manual. If  I had, I would have used quotation marks. I stated this is OUTLINED in the manual. I did not say this is a DIRECT QUOTE from the manual. Geeez! And, please note I did say 4JH4 manual, not 4JH3 as you are quoting.

 

But if you want specific details of the JH4 Operation Manual, publication number OAJH4-G00102, page 78. I quote, “Periodically operate the engine near maximum speed while underway. This will generate higher exhaust temperatures, which help clean out hard carbon deposits, maintain engine performance and prolong the life of the engine”

This is below the section you quote about running it in idle and speaks specifically about running the engine while underway.

 

Regardless of whether this is done in neutral or in gear while underway, the purpose of the procedure is to raise the internal temperature of the engine periodically to remove carbon build up. Carbon build up will kill a diesel engine.

 

I’m feelin’ a little crabby today. Can you tell?

Hi Mark,

Regarding "Running a lower RPMs without load will shorten the life of the engine unless it is pushed up at least once per hour for about 5 minutes. This is outlinede in the Yanmar operation manual."

 

This is not to challenge the veracity of your statement but I cannot find that in my Yanmar manual. Maybe you have a different manual and it would be helpful (really) to have you quote what it says. 

 

What my 4JH3-HTE Operation Manual says (on page 30 section 4.6) is: 

 

"When operating the engine at low speed ffor long periods of time, race the engine once every 2 hours"..."Racing the Engine, Morse Remote Control Handle Pull out the handle lever...and shift the engine speed from high to low several times...Racing the engine removes carbon built up in the compustion chamber around the fuel injection valve.  Neglecting to race tthe engine will cause the exhaust to turn black and lower the efficiency of the engine".

 

In other words it says to gun the engine several times while it is in neutral.

 

Like others, we vary my speed between 1600 and 2200 for cruising and can cruise up to 2400 rpm.  We also run it at say 2800 for 5 minutes or so periodically.  However, I cannot find where Yanmar recommends this.  There are postings in this group (not yours) that say to run it full out for 5 minutes, even full out fo 30 minutes but I don't think that is advisable. Seems that vibration is higher and it might be hard on the transmission and c drive as well.  Like most of us we vary the speed and run it harder at times but we also do the "Racing" procedure that is in our manual.

Re: [Amel Yacht Owners] engine cruising RPM

Mark Erdos
 

Teun,

 

Common rail engines have been around for years and while they offer lower emissions and soot from the exhaust they are not the cure-all. The thing to remember here is all marine diesel engines are engines designed for land adapted to a marine application. No diesel engine is designed to run at 25% power for days on end. If a land based application called for only 25 hp then a 25 hp engine would be used, not a 110 hp engine. It is my opinion the even the most modern newest technologically advanced diesel engine still has emission issues (soot and carbon buildup) at low end rpms. Look at the recent history of VW and how they adjusted the software of the engine to trick the emissions computers. They did this because their latest efforts at design and massive expenditure failed to produce a clean burning diesel engine.

 

So, the question I have for you is, what does it hurt to push up the RPM once in a while? If the engine is designed to run at x RPM then it should be able to run at 80% of x rpm for at least five minutes per hour, should it not?

 

 

With best regards,

 

Mark

Hi Porter,

 

I understood you had a new VOLVO installed. If so, and it is a common rail, then there is NO need to run the engine on high rpms to “burn out the soot”.

 

This is the specific instruction I got this week from the SYDNEY VOLVO technician installing my VOLVO D3 110 H here in NOUMEA NEW CALEDONIA.

Thanks Mark,
Good to know, just couldn't find it in our manual so I do appreciate the citation from the other Yanmar manual.  Based on that I think I feel better about operating at higher speeds periodically--we max out at about 3300 rpm.

Hi Ryan,

Hi all,

I've dug through the forum history on the topic of the "correct" RPM range for the Super Maramu, and I haven't quite found what I want.  What I have learned is there probably is no single, correct answer -- it depends on the engine and the prop.  But what I really want to know is not what RPM I should be seeing at wide open throttle, but what RPM I should be cruising at?  By this I mean the RPM you would use if you needed to motor for a long period of time.  If the max RPM is different for everyone, it stands to reason that cruising RPM should also be different for everyone.  Is there some way of calculating this RPM from the max?  I've heard a rule of thumb of 80% of max RPM, but given that some of our engines are "over-propped" by design, I don't know if it applies, or even if it's a good rule in the first place.  Should we rev to whatever is necessary to go a certain speed?  Is there any harm in operating the engine close to/at wide open throttle for extended periods of time?

For the record, I have a Volvo TMD22 (B?)...  I typically cruise at around 2400rpm, which yields a boat speed of about 6.5kts.  I have a fixed three-blade prop (probably the original spare).  I think the boat went faster at this RPM last year when I first bought her, but that could be me misremembering the RPM, or the tachometer going out of calibration, or the fact that I badly need a bottom job (though I had it scraped only a couple weeks ago).  I do not know my max RPM; my engine needs a new timing belt and I don't think it's prudent to stress it until that is replaced.  The fastest I've gone is about 2600 and I'm sure it can go higher.  I saw around 7.2kts STW at that speed.
