Re: Volvo RPM issue

Hi Doug,

 Just a comment on running your engine at the dock---if you have an Autoprop it will not load up  properly when the boat is tied to a dock as there is not the flow of water that you get when the boat is moving. Because of that, it's not difficult to get to full revs at a dock.
 That can be a problem if you run aground. I don't think you get the full power out of an Autoprop when stationary. Just avoid those sand banks  ( as we didn't once in the USVIs ....)

Hi Doug,

Checking wide-open throttle at the dock may not necessarily reflect what you see underway.  The vacuum pressure in the engine is usually dramatically different under full load conditions versus no load.

There is a vacuum operated device on the turbo I have always heard called a waste gate, Volvo calls it a turbo actuator.  This device is a valve that controls the flow of exhaust gases to the turbine wheel.  If the vacuum pressure is not correct the turbo will never develop full boost pressure.  I am not sure of the D3 spec on vacuum but it might be worthwhile to try and measure it if the following does not work.  You may have a vacuum leak somewhere in the system. 

Take a look at the OEM Fault Codes shown on the Volvo multifunction display; see the attached PDF on how to retrieve those fault codes to see if any refer to the turbo.  Next, take a look at the Volvo service bulletin regarding the turbo actuator – be sure to click on the “Comments” at the top of your PDF reader for additional information.  It does take a little bit of effort to push the linkage causing the vacuum actuator and wastegate to operate manually.

Good luck!!

Hi all,

Furuno tells me I have an older FA50 which is not capable of silent mode. Their solution? Buy a new one... 😅


Re: Volvo RPM issue

 

Doug,

All I can add is that in your situation it is almost always the autoprop.

One barnacle on one blade at just the right spot can cause that single blade to dig deeper in the water. Also, I am sure that you are aware of the AutoProp bearing replacement intervals of 800 hours. I have seen others replace the bearings between 800 and 1200 without an issue. You didn't mention the bearings and I am betting the previous owner never replaced them.

Yes, the auto prop was moving nicely when we hauled out and I had lubricated it and cleaned it externally prior to launch. I think it is good. 
As for a laser tach, no, I haven’t done that, since the sounds and speed match the engine tach. I can hear the engine as it speeds up to that level and the boat hits 7 knots  on flat water at 1650 rpms. 1250, 6 knots, and at about 1400, 6.7-6.8.
No sound of any thing irregular at those rpms.

Have you checked the accuracy of the dashboard tach with a separate measurement?  Maybe a laser tach on the flywheel?

Does the boat speed reflect the lower RPM's you see? In other words, does the boat run at the speed you expect at 2070 RPM?  Or is it faster, like you used to get at full throttle?

The proper way is to blow air into the condenser. Not only it improves the heat transfer by blowing cooler air into the condenser but , more importantly, it filters the air before it is blown into it

Hi Doug,
I had exactly the same problem with my TMD 78 HP. But it never got up to 3Krpm, unlike yours.  I spent thousands trying to figure it out.  Brunton (AutoProp) told me that my H6 was the correct prop for a SM with 100HP Yanmar.  Likewise King Propulsion, prop shop extrodinaire in Norfolk area said my fixed prop was over pitched.  Since the prop blades spun freely, I ignored advice on this forum to service it...bad move...

Here are a couple other things to look at:

Look at the exhaust elbow to make sure it isn't clogged with carbon.  If that's ok, service the AutoProp...even if the blades turn freely.

Have you looked at fuel lines and changed fuel filters? A kink, blockage, or stopped up filter could be your problem.

I'm betting it will be solved by servicing the AutoProp if you don't find an exhaust or fuel restriction.  Contact Rod at King Propulsion if you need help.  Great guy, very knowledgeable.

We did the white silicone on Aletes as well. Due to silicone’s shrinkage, we found it necessary to overfill with a good crown to the surface of the silicone. Then, after curing, slice it off flush with a razor.

Re: Jib car track plugs -- how many?

A second vote for silicone.  We ordered the polyethylene plugs from Amel early on in our ownership.  They only good thing about them is that they were cheap.  They lasted less than a year in the tropics before crumbling to uselessness. A very poor solution.  We filled them with gray GE SCS2002 silicone 5 years ago.  They are still 100% perfect.  This is a neutral cure silicone, and totally compatible with the aluminum track.

If we ever NEED to pull out these bolts, removing the silicone plugs would be a time consuming chore, but certainly not impossible.  In the meantime, the silicone plugs are a very satisfactory esthetic AND functional solution.

Re: Cooling Super Maramu Refrigeration Units

Bill Kinney
 

Paul,

I think you are worried about differences that, while theoretically true, matter little in the real world.  In my experience, the temperature of the air under the settee is trivially different than the air in the cabin.  The amount of air moved by the fan is also so slightly different in the two directions that it doesn't really matter.

Far more important is to keep the condenser clean and free of dust and dirt.  Even a light coating of dirt will have a far bigger impact on heat transfer.

Cooling Super Maramu Refrigeration Units

Paul Stascavage
 

I thought I would throw this out to the group and see what those more knowledgeable than myself had to say.

I recently had to replace a bad fan on the aft salon refrigeration chest.  The fan I was replacing was installed to draw air from the salon, over the condenser, and into the compartment where the compressor and electronics are housed (sucking cooler air over the condenser).

When I looked at the forward unit in the salon, the fan was mounted the opposite way. That unit draws air from the compartment where the unit is installed, and blows it over the condenser and out into the salon (blowing warmer air over the condenser).  Additionally, this fan was the same brand and model sold by Coastal Climate Control (a US Frigoboat Distributor) which made me wonder if this was the original fan with the original Amel installation (blowing air out).

The Frigoboat installation  instructions seem to imply that the original set up is to blow air from the installed compartment and out (to the salon in our case):

“These units are designed to be mounted with compressor right way up on a horizontal surface in areas where they will not be susceptible to physical or water damage, but accessible for service. They require good ventilation, preferably expelling the heated air to another location by attaching a flexible duct of not more than 6' in length to the duct ring on the unit. A duct kit is available for Capri 35 and Capri 50 models. Do not add any filter type material anywhere in the air flow.

If air is required to be drawn into the unit from another area, the fan may be reversed by removing the housing and re-mounting the fan in the opposite orientation. Reversing the fan leads does not make the fan run in reverse, and the incorrect polarity will result in the fan not operating.

There should be adequate ventilation to allow cool air to enter the condenser, and precautions made to prevent the heated expelled air from being drawn back in. The temperature of the air entering the condenser determines the efficiency of the system. Re-circulating the heated air back into the condenser in a sealed or poorly ventilated cabinet will result in poor system performance. Poor system performance will also result from air being drawn in from a heated space, i.e. an engine room.”

Google searches seem to imply that these fans do a better job blowing than they do sucking, so the question is, what is better?  Blowing a lot of warmer air over the condenser and out into the salon or sucking less’ but cooler air over the condenser and into the installation compartment where all the heat is generated?

I tested the forward fridge unit with the fan installed both ways and the unit ran for basically the same amount of time regardless of fan direction, although the cabin temperature was only 74 degrees Fahrenheit.  I imagine things might be different at higher temperatures (which I plan to check).

My feeling is that the better mode of operation is to introduce cooler air over the condenser and into the installation area.  I believe this would be the more effective way to both cool the condenser efficiently and cool the area where the heat is being generated (compressor definitely felt cooler to the touch drawing air in rather that blowing it out).  Additionally, having the fan blow from the installation compartment and into the salon means that the dust is going to collect on the compartment face of the condenser.  To me, that translates to a situation whereby the condenser is rarely getting cleaned as you would have to gain access the area, remove the fan, and get the vacuum at it (another project for the list).

With the fan drawing air into the condenser, you can easily inspect the condenser from the salon and give it a cleaning whenever the vacuum is out to clean the floor.

As I said, I plan to do some more testing when we get to warmer climates, but I am curios to find out how others currently have their fans installed and any thoughts on which way is indeed best for our installations?

Incidentally, our galley fridge is also set up to draw air from the galley, over the condenser, and then towards the compressor.

Thank you in advance for any and all replies.

All the best,

Volvo RPM issue

Doug Smith
 

Question for the group.

I have seen many messages from a few of you with the Volvo D3-110, where you have worked on or around the turbo. I have read through most that I could find and spoken to a couple of you to try to figure out our issue.

I have a Volvo D3-110-I C, and it has around 2000 hours on it.  I purchased it 24 months ago, and on survey it would run up to 3000 RPM’s. After running it on a longer passage, of 5 days, at 1500 RPM, I haven’t been able to get up to 3000 RPM’s again. When moving the throttle forward, the engine will climb to about 1500-1600 and slowly over the course of 2-3 seconds continue climbing up to 2070.  No more. At the dock and in neutral, it will easily climb to 3000, without hesitancy and the engine is responsive to the throttle appropriately.  I lubricated the external turbo actuator, but it didn’t change the hesitancy or the top RPM and it moves freely.

Next, I did the seasonal haulout, and the bottom was cleaned and the prop was shiny again. All blades of the autoprop were free to rotate.

The first day back in the water, I could get to 3000, and I figured my problem was solved.  But literally the next week, I was unable to get back to 3000.  Same exact sense at the throttle, and same top RPM of 2070.

So I had the turbo rebuilt.  In speaking with Mark McGovern, he was confident that a good cleaning would likely be needed after the prolonged running at 1500.  Rebuilding a turbo, seemed too precise a job, so I had it professionally done, and the guy who did it felt there was some carbon build up, and after replacing the internal bearings, assured me this one would run like new. After reinstalling it, no change. At all. 2070.  Same hesitancy at the throttle.

So then I came across those threads speaking of the Turbo boost pressure sensor, Bosch 31355463.  Certainly, that must be it.  No change after installing it.

The engine starts easily, runs at a good temperature, and seems to perform well at the lower RPM’s. 1500 is the sweet spot. Runs fine up to 1800-1900. The transmission has a new filter and new fluid.  The C-drive Wear bushing, seals and fluid have all been recently changed. I double checked the tightness of the exhaust manifold, and the mixing elbow is clear.
Air filter intake is clean and the filter is new. And no error codes on the dash display.
Running out of ideas here, and hoping someone out there has some experience with this type of problem. I would happily bring a Volvo mechanic on board, to solve this, but have heard so many experiences from the group that suggests this might not be easily fixed by them.

 

Thank you for any of your thoughts on this.

Maud got back to me and said that these sensors are no longer available.  She suggested another sensor made by a US company - SICK (not a typo).

She indicated that these new sensors would have to be mounted a little differently.  I imagine their size is a bit different.  I am still waiting for a quote and estimated shipping time.

I will update the post when I get to the root of the problem and provide some more information regarding the sensors when they arrive.
