Re: [Amel Yacht Owners] Water ingress

 

Paul, 

Two things:
  1. If you look closely under the shower pan in the forward head, you will see places where water can go when the boat is heeling...it will get trapped there until your next rough passage.
  2. Water passing by the Thruster Tube seal will run downhill to the area outside the head. It's path will dry quickly.

Expected RPM at WOT

Porter McRoberts
 

Thank you everyone for your thoughts re our engine woes they are quite appreciated. 

May I ask thoughts re expected rpm during WOT with the supplied fixed prop on the Amel 54?


Has anyone with the fixed prop determined an observed RPM with WOT?  Volvo is telling me that they think 2200 is due to too large a prop. Now I know the H6 is a slight over propping, reducing the expected 3100-3200 Volvo D3-110 to your observed 2900ish range. 

But 2200 (our WOT RPM with the fixed prop in calm seas) is much lower than 2900, and I have a hard time thinking such a great drop is due to the lack of prop arm adjustment for appropriate bite as seen with the autoprop. 

Any data would be very appreciated. 

Many thanks

So the fixed blade prop stops it right. Therefore there is nothing wrong with the engine itself.

Thus it must be something to do with the Bruntons Autoprop, which is a variable pitch prop.

The pitch varies automatically in order to maximise efficiency. "The Autoprop blades, unlike those of conventional propellers, maximise the thrust delivered whatever rpm the yachts engine is running at “

So if the thrust  is maximised at all times then load on the engine must vary a bit. Just like say the big alternator kicking in when one runs a heavy load off it, say a toaster for example. So I would expect a slight variability in the rpm as the load on the engine varies but not like in your video.

Agreed there is something wrong with the prop. You could strip it down yourself, it is pretty easy, before returning for service.

I checked my WOT this morning in flat water/no wind and it was stable at 2920rpm.  

I also took a short video of the wandering I was referring to, its in the" ZF25 Transmission" folder in the files section.  It shows a variation from 1170 to 1210, difficult to hear the engine note on the video, but 40rpm variation is just enough to make the ears prick up!.

Be careful, Onan offered two different remote switches and changed the switches over time. What one boat has may not be what another has.

Re: D3-110I-C Wandering RPM and Disk break

Rudolf Waldispuehl
 

Hi Dean

Nice to her that your gearbox installation went well. 

I never had any wandering RPM since owning WASABI (last 5 month of cruising).
But my shaft break gave up holding the disk above 6 knots of sailing speed. I turned the fastening screw on the cylinder both way. But tightening the brake pads to stop turning was not possible. 
If I’m correct I did the fastening according the instructions in the owners manual but no result. The Breck-Pads still have 4-5 mm on. 

Probably it’s the "pressure-cylinder mounting" who is weak. I doubt the mounting system is a very long lasting engineering solution? So I did an interims solution with some Tools on board and it works for the time being. @Dean, I’m curious how is your disk break system is installed. If possible I will have a look in Preveza. 

Best regards and cheers

Betreff: [Amel Yacht Owners] D3-110I-C Wandering RPM

 

Hi Gang,
I’ve been wondering for most of this summer about the wandering rpm in my D3-110-C motor. I’ve noticed that occasionally the rpm will wander around by 20-40rpm over a period of a second or so. It is obvious to the ear, as well as being shown in the instrument readout, and seems to be particularly prevalent when mooching around in the 1000-1500 rpm range. Haven’t noticed it so much at higher rpm.

I also don’t recall hearing it last year, but we were pretty overloaded with new stuff last year, it’s possible I just didn’t notice it.

Since I’ve now installed a new gearbox, I’ve kind of eliminated any issues on that front (ie pressure drops/shaft brake application)

This year I changed from the original fixed prop to an Autoprop, which is also a new piece of kit to me. Could this be related to the autoprop blades doing something erratic and momentarily loading up the motor?

Do others observe this behaviour? I guess with the trials and tribulations that Porter has gone through this year with his D3-110 we are all paying a bit more attention to this troublesome power plant.

Many thanks

Re: [Amel Yacht Owners] D3-110I-C Wandering RPM

Hi porter;

We hauled out in July this year in Malta. I had noticed the same issue with the prop of one blade not being as smooth as others during the previous haul out in December 2016 and observed the same this year.

After discussing the issue and the number of hours on our engine (About 1800) Brunton’s stated that they recommend a rebuild of the prop at around our engine hours. We had the complete rebuild kit on board so we replaced all replaceable parts (mostly bearings and seals).

Before the rebuild our WOT was 2780 RPM and 8.6 knots SOG. After the rebuild WOT 2930 and SOG 9.4 knots.

Sand and 3 new coats of Micron 350 and new prop speed applied to the prop. So I’m sure the anti fouling and the clean prop added to the differences seen and not sure how much of it was due to the prop rebuild.

Our speeds have dramatically increased at all RPMs (about 0.5 to 0.8 knots) both under power and sail. So it is unclear how much of it is due to the prop rebuild but it was time in any case, according to the manufacturer.

Sorry to hear about your issues and glad you are sticking with it. Hopefully it will soon smooth out and you can start working on “normal” cruising repairs. Lol.

Respectfully;

Could play increase in the c-drive with warm oil and cause the slight wandering?  Why after an hour did that present.

Hello Dean, and hive of cognoscenti.


Please have a look at this video if you’d be so kind:



I started noticing your description several months ago. Pre boost pressure sensor fault, pre long block failure. We hauled out in Martinique in April. Serviced c drive, autoprop etc. I noticed that 2 of the autoprop arms fell with gravity alone. The third needed coaxing from a finger. More grease and it was better but never equivalent to the other 2. Minimal vibration. Hard to know how much vibration is normal as only have had the boat 1.5 years. Never motored on another 54 or SM for that matter. 

So.... after finding sputtering oil from the dipstick confirming to Volvo the Long block was shot we had a new long block installed and engine back in the boat Friday with sea trial last Saturday. While out of the water I sanded and acid washed the prop. Still noted one arm stiffer than the other. But not worse that it had been. 

During the sea-trial we had  Lots of rpm variability such as dean described but even +/-50-100 rpm. But not close to what is seen in the video. Our WOT was held to 2360. CDM/Volvo with their vodia computers hooked to the engine blessed it and said it was good. Hands washed they said the variability had to come from the prop. (I had not disclosed my observations under the hull while out of the water). 

This Last Monday real world test: we set out southwest from Panama City to isla Contadora. RPM wandering was much higher- this is when Video was taken. Wasn’t the most relaxing of trips in addition to being late and arriving in the dark we had an explosion of late afternoon lightning storms with webs of red and blue current above us. 

So we’re at anchor south of Contadora, arrived safely and this am I dove and switched the autoprop to the fixed, spare prop. Thanks Bill Rouse and James Cromie!  

Sea-trial this afternoon. 

I’ll report findings. 

Thanks to everyone!!

Re: Installing diesel heating on a Super Maramu

Jeppe Jonsson
 

Hi fellow SM owners
I am also planning to install diesel heating, however my SM does not have the forced air option. In the cockpit locker I can find a large duct going down under the galley - ending there. Furthermore there is also a small duct leading to the front cabin. Both these are closed off. I will use these.

My question is where to find or where to install a duct to the aft cabin?

If you have heating to the aft cabin, how does it enter from the cockpit locker?

Kind regards

2000 rpm temp 81c and 70 kPa quiet

2200 rpm WOT 84c and 110/120 kPa quiet


Zero rpm wandering for first hour, slight wandering after an hour. 


I guess it was the prop!?!


I’ll send it back to be rebuilt. 


I’ll also be interested to see what a longer motor is like. 


Could play increase in the c-drive with warm oil and cause the slight wandering?  Why after an hour did that present. 


Also. Other question sent to Volvo: what’s up with the 2200 wot???  Ended up going 8.6 kts sog one direction and 9.2 kts sog in the other. Minimal chop.

Hello Dean, and hive of cognoscenti.


Please have a look at this video if you’d be so kind:



I started noticing your description several months ago. Pre boost pressure sensor fault, pre long block failure. We hauled out in Martinique in April. Serviced c drive, autoprop etc. I noticed that 2 of the autoprop arms fell with gravity alone. The third needed coaxing from a finger. More grease and it was better but never equivalent to the other 2. Minimal vibration. Hard to know how much vibration is normal as only have had the boat 1.5 years. Never motored on another 54 or SM for that matter. 

So.... after finding sputtering oil from the dipstick confirming to Volvo the Long block was shot we had a new long block installed and engine back in the boat Friday with sea trial last Saturday. While out of the water I sanded and acid washed the prop. Still noted one arm stiffer than the other. But not worse that it had been. 

During the sea-trial we had  Lots of rpm variability such as dean described but even +/-50-100 rpm. But not close to what is seen in the video. Our WOT was held to 2360. CDM/Volvo with their vodia computers hooked to the engine blessed it and said it was good. Hands washed they said the variability had to come from the prop. (I had not disclosed my observations under the hull while out of the water). 

This Last Monday real world test: we set out southwest from Panama City to isla Contadora. RPM wandering was much higher- this is when Video was taken. Wasn’t the most relaxing of trips in addition to being late and arriving in the dark we had an explosion of late afternoon lightning storms with webs of red and blue current above us. 

So we’re at anchor south of Contadora, arrived safely and this am I dove and switched the autoprop to the fixed, spare prop. Thanks Bill Rouse and James Cromie!  

Sea-trial this afternoon. 

I’ll report findings. 

Thanks to everyone!!

Hi Gang,
I’ve been wondering for most of this summer about the wandering rpm in my D3-110-C motor. I’ve noticed that occasionally the rpm will wander around by 20-40rpm over a period of a second or so. It is obvious to the ear, as well as being shown in the instrument readout, and seems to be particularly prevalent when mooching around in the 1000-1500 rpm range. Haven’t noticed it so much at higher rpm.

I also don’t recall hearing it last year, but we were pretty overloaded with new stuff last year, it’s possible I just didn’t notice it.

Since I’ve now installed a new gearbox, I’ve kind of eliminated any issues on that front (ie pressure drops/shaft brake application)

This year I changed from the original fixed prop to an Autoprop, which is also a new piece of kit to me. Could this be related to the autoprop blades doing something erratic and momentarily loading up the motor?

Do others observe this behaviour? I guess with the trials and tribulations that Porter has gone through this year with his D3-110 we are all paying a bit more attention to this troublesome power plant.

Many thanks
Dean

Good morning Alin

We thank you for your message but unfortunately stability data do not exist for the Super Maramu.

The only document we can propose is the “EC type examination certificate” (copy attached).

Sorry not to be helpful

Best regards

Hello. 

My name is Alin Misescu and I am a proud owner of a Super maramu  hull 283.

I wanna put her into charter in NZ and my surveyor asks for more stability details.  Can you please help me to get them? 

Best regards
