OK.  If the switch is down,  the pump should not run as the float ball/switch is at the bottom of the travel.

The pump starts when the float ball/switch reaches the top of its stroke.

Also, on the left side in the cabinet above the galley, you will find the Manual/AUTO switch referred to in my original reply.

Is the switch located in the cabinet containing the autopilot above the galley sinks?

Re: Onan Water Pump

Alan Leslie
 

I replaced the original Onan pump with the Sherwood some years ago.
It has a one piece casting instead of a detachable end plate.
I thought its construction may help to extend the life of the impeller.
At that time I also changed to run dry globe impellers....they didn't make any difference...the impellers where still failing at around 170 hours.
But at the last change I put in a standard impeller and it's up to 240 hours now!
Is that just luck? I don't know...I don't think anyone else does either !

Thank for your post.  I actually had a rebuild kit on board (memory is an occasional thing for me these days it seems) and though easi-peasi, just rebuild the pump!  But it will take a shop to get this one apart.

I agree with you, another pump is the way to go.

Re: Onan Water Pump

Mark,

You're absolutely right, the Sherwood pump is the G702.  It looks exactly like the one on the engine and some on-line sellers list the Onan part number with the Sherwood part number.

Thanks!

Re: [Amel Yacht Owners] Re: Onan Water Pump

 

Duane,

I looked at your illustration. When water exits where you illustrated, the internal seal is leaking  and the pump has to be rebuilt. I had 2 water pumps and switched them when the impeller timetable called for a new impeller. I also had the rebuild kit for this pump, but never rebuilt it. I believe the bearing is pressed on with a hydraulic press. Hence, the reason that I had two pumps.

Can the shaft (part 1) be removed without worrying about orientation?  Would you also replace the Body (part 3)?

The local West Marine rep told me I'd probably have to go to Annapolis for the parts, since you're in Annapolis any suggestions?  I'm now in Lewes, DE on our way to Marthas V ineyard and Cape Cod.

Re: [Amel Yacht Owners] engine cruising RPM

Barry, " Rubbish" , that was a bit harsh, all I suggested was to run it at a rpm that sounded good,in other words not laboring too hard, and then once in awhile run it a little harder to blow out carbon deposits. Sounds like what you do. Go back to bed mate, and get up on the other side.

Re: [Amel Yacht Owners] engine cruising RPM

Patrick McAneny
 

Ryan , I have a Volvo TMD22A ,I also have a fixed prop for now,soon going to purchase a feathering prop, and I max out at 3100 rpm @ 8.3 kts., 2200 sounds good and gets me 6.5 kts. However max rpm on this engine is 4500 and I have been wrestling with how I should pitch my new prop. The prop manufacturers believe I should be able to attain 4500, otherwise I am leaving HP. on the table. But 80% of that would be 3600 RPM and I don't want to run the engine at those rpms all day, fuel/noise and wear. Your in one of those gray areas ,where there is no correct or incorrect answer. Take her up until you hear a sweet spot and run her there ,then once in awhile take her up to a full gallop.

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.

Re: [Amel Yacht Owners] engine cruising RPM

Barry Ferguson <seagasm@...>
 

You are going to all sorts of advise and as always, the opinion of the reply is always best. Troll around some 4x4 forums where you will obtain very good hints like install a catch can. Now, my own experience is this, my SM has a TMD22A installed, this is a Turbo version of the Volvo built by Perkins. Incidently, these are believed to be in most taxis around London. With the older Autoprop which is lubricated by sea water, I cruise under power only at 6 knots at 2000 rpm, the speed of course varies depending on sea conditions. I don’t bother going any faster as this seems to be a very comfortable temperature for the engine. On such a trip I will open her up to full 3000 rpm for about 5 minutes, prior to entering my destination, allowing the temperature to drop back to normal. I motored ALL the way from Noumea to Bundaberg in perfectly calm conditions with the engine purring away all the time at 2000 rpm. I have experienced trial drag races with another boat of 8 knots at 3000 rpm in glassy conditions up in Hitchbrook Island without running over a Croc (I think) and it will not get better so I am happy. However, I have ditched the Autoprop in favour of the spare fixed prop since this seems to run smoother but not quite the performance but I still maintain that 2000 rpm. It’s a cruising boat.

Re: [Amel Yacht Owners] engine cruising RPM

greatketch@...
 

Full throttle for us is 3000 rpm at 8knots when the bottom is shiny clean. Our normal cruise is 2000 at 6knots.  Bumped up occasionally to 2800 to get things hot.  Speeds are slower if it’s rough, of course.

That’s pretty much the normal expected values for the Super Maramu with the TMD22.

We have the MaxProp.  I’d guess your fixed prop would be incrementally more efficient.

The engine is not really rated to run at full power output indefinetly, but should have no trouble with 80%.

Re: [Amel Yacht Owners] Re: Onan Water Pump

Mark Erdos
 

Duane,

 

I can’t help with the parts for this but suggest you have at least two pumps aboard. I use two pumps in rotation. Rather pull the plate off to access the impeller, I swap out the entire pump. It is only two bolts. It is much easier to replace the impeller with the pump off than do it when on the genset. The 3rd pump is a spare (new)

 

FYI: The pump is made by Sherwood and is a lot cheaper on Amazon or eBay rather than Onan (if memory serves well it is Sherwood Pump G702)

 

Also, I added a trap to catch impeller fragments between the pump outlet hose and the heat exchanger. This is much easier than having to retrieve impeller blades from the heat exchanger.

 

Hope this hopes. I figured, whilst you are there you could make it better.

 

 

With best regards,

 

Mark

Re: [Amel Yacht Owners] engine cruising RPM

Mark Erdos
 

Ryan,

 

This is the age old question! Should I run at a higher RPM for an extra knot but half the fuel efficiency? The diesel engine manufacturer says yes, my wallet says no.

 

Our personal preference under engine only is about 1800 RPM (Yanmar 4jh4). This is where we burn about a gallon of fuel per hour and can get about 6 knots pretty easily. When motor sailing – we will run at 14-1500 RPM. The fuel burn is about ¾ gal per hour.

 

If you decide to run the engine at lower RPM to save fuel (as we do), then it is very important to run the engine hard for about 5 minutes every hour. For us this is 26-2800 RPM. This will eliminate carbon build up in the exhaust system and prolong the life of the engine. Diesel engines prefer to be run hard about 80% of max RPM. 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. I would assume the same is true for Volvo.

 

Hope this helps

 

 

With best regards,

 

Mark
