Re: Volvo D2-75 Repower

Ian and Judy,

Volvo is right, the engine does not need isolation. BUT, the engine ground system is not isolated to protect the engine.

The C-drive needs to be connected to the Amel bonding system for corrosion control.  Unless extra ordinary measures are taken, the engine chassis is going to be electrically connected to the C-drive.  Having a full time negative ground on the engine chassis results in full time connection of the 12-Volt Negative connected to the bonding system. Having these two system interconnected  is not the way the Amel corrosion control system is designed.

The problem here is if ANY other part of the bonding system has an inadvertent connection to the 12-Volt positive, very severe, and rapid, corrosion can occur. This will not show up on the ground fault lights because those only test for a faults in the 24-Volt system.

Does yours look like this

My cover and it’s spare are now cracked so I have also been hunting for the spare and struggling. I have emailed Aquafax in the uk as they apparently supply BEP marine parts but I’m not actually 100% it’s the same piece as the specs are not clear on the BEP website. 
Looks like the vital parts covers are well worth a go!

Hi Paul,

I have had the D2-75 for 4 years. 850 hours. All good. More torque than the TMD22. so not sensitive to fouling on the prop Noticeably lighter Stern rides higher. Happy with it. After a year the turbo was replaced under warranty, no problems since. Amel advised not to go for the 110hp as the C drive in 299 was not built to take that power. The C drive was upgraded in the models that had the 110 fitted. In retrospect I would consider an overhaul of the TMD 22 instead at a much lower cost, not because of any issues with the new motor.

Thanks Bill.  Having a strong Physics/Calculus background plus being a pilot and then a process control designer when I was still young and smart made it easy for me to understand these things. I did spend quite a bit of time with Kent's (rather excellent IMHO) B&G/Simrad system and know what you mean about their manuals.  I think a lot of these manufacturers are in a tough spot... if they open up the control settings too much there are those of us who will fiddle with them and drive up their support costs when the boat is acting wildly but then if they dumb them down too much, they don't perform as they should.

Re: NMEA 2000 to NMEA 0183

Hi Paul.  I had a look at the manual of the ACU 400 and you are right in that they have dumbed down the controls a bit to make it easier for the end user.  The Response level seems straightforward enough... performance would be when you want it to be highly responsive (i.e. acting faster) while Leisure would be when you don't need it to react that fast (so like what I had said above (higher Response = Performance, lower = Leisure).  I guess they felt that three levels was probably enough, I like to fidget a bit more than that but for the average person, I'm sure it's fine.  They still sort of have Rudder Gain and Counter Rudder but they've integrated it into the Boat Type, Rudder Limit and Hard Over Time/Drive Check functions.  If you have a rudder sensor, they can figure some of that out automagically it looks like (the Rudder Limits and Hard Over Time specifically).  Basically what they are doing is calculating the required gain settings from the responsiveness of the rudder and an approximation of the boat speed (sailboat or sailboat (slow turn) and rudder response times).  I would check to make sure that your boat is set properly for SAILBOAT or SAILBOAT (SLOW TURN) and that the Rudder Drive/Hard Over Times are set properly (HOT is only used if you don't have a rudder angle transducer as it can figure it out if you have one).  If you still find it is acting a bit slow, try changing the boat type up to Catamaran or slow powerboat as that's bumping the gain function.     I'm surprised that they don't have a Wind Trim function for the Evo units but I guess that they were having trouble with people not understanding how it overrides the gain/response of the regular settings.  You can have similar function but you'll need to boost the Response during changing conditions.  You'd think with all the electronics in these things that they'd give you MORE choices (even if they put it behind an "advanced settings" menu) rather than less.  Good luck!

Hi Paul,

 We have about 30 hours on our D2-75. Its a good fit. The guy who installed it originally worked with the Brit who designed the TMD22 so he knows both engines well. The TMD was designed for road use and then marinised whereas the D2-75 was designed as a marine engine. Neater and more accessible. No lack of power compared to the TMD22. It is marginally noisier as it is not belt driven. Wonderfully clean exhaust. I expect fuel consumption to be the same.
The secret switch used to interrupt the power to the switch board but now interrupts the power to the starter. Volvo insist  that this engine does  not need galvanic isolation  but I like the belt and braces approach of the original so will resolve that--pending that, I have fitted the Autoprop with the  zinc cap that Autoprop supply.

Early days, but we are very pleased.

Re: Eumania dishwasher water inlet solenoid

My dishwasher also has a continuous dribble from the inlet valve, presumably due to a defective solenoid valve.  We have to turn the water valve on to wash and turn it off at the end of the cycle to keep the washer from accumulating water.

So that's great news you found a possible replacement.  Please let us know if it fits.

Re: NMEA 2000 to NMEA 0183

Brent Cameron
 

Paul, it sounds like your autopilot gain and response settings are off.  I’m not familiar with your exact unit but most autopilots have settings for Wind Trim, Rudder Gain, Counter Rudder and Response.  They are basically just little programable logic controllers (PLC’s) that act to minimimize the difference between the input value (course, heading, wind angle, etc) and the set point. To do this, they NEED small pertubutions and then based on the size of the deviation, they apply a correction. For us, those perturbations are usually waves!  

Anyway, that correction takes three main forms. The most oblivious is the Rudder Gain. I’m really going to dumb it down (there are text books written on control algorithms) but you can think of gain like boosting the effect of the correction (i.e. how much rudder to use to get it back on course after the pertubution). Too little and it won’t work. Too much and you over correct and that can set up a nasty cycle of the boat wandering all over the place and never getting back on course. This isn’t exactly right but for your purposes, the analogy works. The second main variable is the Counter Rudder which you can think of as how big an opposite movement of the helm is required to stop the turning motion.  Too big, and the boat overshoots and wanders all over the place.  The balance between the Rudder Gain and Counter Rudder is crucial to goood course keeping. The two settings should be pretty close to each other and certainly no more than two settings apart.  If you were helming the boat, you wouldn’t wind the wheel from crank to crank to adjust for small deviations... you’d use the smallest adjustment you could, so again, the goal is to find the minimum setting that will get the boat back on course.  But it is also tied into the Response. 

For the Response, you can think of that as how many corrections per minute it uses to get the boat back on course. Think of it as if you were making a correction how often you’d want to wait to try the next one. The higher the Response the faster it will act but again it can be set too high so that the rudder is moving all the time which of course really runs down your battery but also causes the boat to hunt. If you watch a good pilot or helmsman, he/she won’t slavishly turn the wheel on every wave but rather averages out the boat’s course to minimize the steering but maintain heading. You want your autopilot to do that. In light conditions, you should knock the response way down to conserve power and reduce hunting but in frisky conditions and especially when steering on wind angle, you’ll need to run it up. A lot of people set it and leave it alone but unless your autopilot has auto response (I’ve seen that the B&G ones change the response based on boat speed which can be a crude approximation), you should adjust it for the conditions.  (The rudder gain and counter rudder are usually autoset during provisioning and then not played with much after that as they are really tied into how well the boat handles excepting if it changes as it gets more frisky). 

The wind trim function allows you to set the sensitivity when acting in wind mode. This is often over-looked but if you are struggling to keep your wind angle, try this rather than the response.  A high value results in the boat following every gust and shift which might be wanted during light conditions with flat water upwind or on downwind on spinnaker but you want a low value when the winds and waves come up on a reach. Most people just leave them at default but that doesn’t optimize your boat’s or your autopilot’s performance. 

Finally, a pet peeve of mine, is to really watch your boat’s Rudder Angle when on autopilot. These autopilots all have Rudder Angle displays but you can also see it by marking your wheel at top dead centre and noting when it is off. I used to be a commercial pilot and it drove me absolutely bonkers to watch other pilots flop on the autopilot and then sit there obliviously when the autopilot keeps adding trim as the plane changed speeds and conditions. It’s the same in our boats. When the wind changes, the sails become out of balance and if you’ve got much rudder on at all, it basically means you’re dragging a big brake in the water. It is literally screaming at you to adjust the sails!  A wee bit of rudder helps us keep the boat stable but that’s really a WEE bit. I hated flying with guys who gripped the wheel like a baseball bat because they couldn’t feel the airplane and they’d constantly overcontrol it and we’d be flinging ourselves across the skies. As a former instructor, I used to teach that you only needed to hold it by the tips of your fingers and feel the pressures. You can’t do that if the plane or boat is out of trim. Same for your autopilot. Get the boat in trim, and your rudder actions (and battery usage) will go WAY down. 

So, to net it out. Make a note of any settings before you change them so you can easily get back to them if needed. Next time there is no wind and you are motoring on a long passage with not much wind,  try playing with the Rudder Gain, Response and Counter Rudder settings (one at a time) while watching your wake. That will give you a really good idea of the effect of each. 

When setting Response, take it off autopilot and hand steer it. Note how often you are correcting it and then set the Response to match that (assuming that you aren’t one of those people who steers the boat from lock to lock on every wave). 

Finally, and most importantly, remember that the autopilot can only respond to HISTORY. It can’t predict what is going to happen, it just responds to what did happen. That’s YOUR job. Knowing how they work and when to mess with the settings is important to optimize your boat’s (and your autopilot’s) performance. 

Again, people that understand control theory are probably screaming under their breath about calculus and integrals but for the layperson, these analogies work.

Hello Derick,

the main cause (which I often see) for the macerator motor to get contaminated with water (and therefore create a contact between 24V and the ground) is that the white plastic casing is often mounted wrong, with drain holes on each side, instead of up and down.
With drain holes on each side, the water leaking from the bowl through the lip seal remains permanently in contact with the motor's casing and corrodes it, leading to a leak from 24V (+ or -) to the ground.
I will try to attach a picture of a wrong mounted macerator plastic casing.

Hello JP, 
I can'y say I'm very happy with my new ACU 400 unit, it works well going up wind but as soon the waves are behind of the beam, it over steer all the time, and I have sometimes to take over to hand steer, no not pleased at all. talked to a boat neighbor yesterday and he have similar problem. Therefor yesterday I installed my old unit, so now I can easily switch between the old and the new unit as well as between linear drive and rotary drive. be interested to see which one that perform the best. the only drawback with the old unit I do not get the wind info.

Hi Barry,
I just cut the sealant with a utility knife from the top and pried it out with a screwdriver, cutting remaining sealant from the bottom as it came up.

There’s a great product made by 3M called Adhesive Remover, Citrus Base that works great for getting the sealant remnants cleaned out before reglazing.


Another good product for this is Marine Formula by DeBond Corp

Re: Eumania dishwasher water inlet solenoid

Gary Wells
 

I just got a replacement 3 valve solenoid for our Eumania washing machine as well. 2 out of the three solenoids leaked, filling the tub with water .. Coincidentally, the manual shutoff valve had a small leak as well so we had to stay on top of it and always turn the fresh water pump off if we were leaving for any length if time (a habit we still like).

Anyway, the new valve has the same specs and fits perfectly; the only caveat was that it has the ''push-in-to-lock' type fittings rather than '''slip-on-and-hose-clamp' barbs. It requires an stiffer and slightly smaller hose so I'm going to have to MacGyver it a bit, methinks.  I'll be glad to have it solved.   Other than that, the 20 year old machine still works fine :)
