Mark, yes I saw them, mine have arrived and will go out to the boat with me in a few weeks.
I do like the dash, it looks really good, nice job. I think I would miss the compass though, you have to teach those students to use one you know!
I remember when I did my DS in Gib, I was asked to take the boat over to Ceuta, I had checked the charts so knew if I followed the compass then the 5m contour it would take me nicely to the entrance. However, the instructor noticed that instead of doing what I said I was going to, I was actually following the chart plotter, he promptly switched it off! Canny lot these instructors....

Elessar, I like the panel mod but the gel coat doesn't look a great match. Is it the light or do you think it will be less obvious when the old gel coat is polished?
Looking forward to seeing the woodwork!

Sealine have a large woodworking shop, laminate comes in from Italy in sheet for either flat, or curved surfaces. They do all the wood forming, bonding and trim.

looking very good so far, just curious where is the extra 30Hp coming from? Is it just a good a service or some tweeking with boost pressures etc?

The Tamd 61a is 306 hp, the tamd62a which is what I have in my boat is 340hp, there are changes to the fuel system, turbo, sea water pump etc that contribute to the extra hp and ability to cool the engines extra kw generated at wot.
Quite how a tweak from col will up them another 30hp without compromising something else I'd be interested to hear as the single heat exchanger is on its limit.
I noticed on the pic thre are k and n air filters fitted, are they the correct size for the airflow into the engine, compare the size to the actual size of the the paper elements fitted to the standard air box .

Nice job on the dashboard Ellesar. Better than factory
Thing is, it wont fit on that ferry anymore. That will make it trickier to get it back to the med?

re air filters - sorry don't want to rain on your parade as its a cracking project so far but....
I am a bit concerned the K&N filters are a bit small and will bung up too quickly - could they then get sucked in??? The original filters have a very large surface area.

The compass will be refitted over to port. No longer in the ideal position but I rarely use it.
For course to steer exercises I get the students answer and dial it into the autopilot. Then they can't cheat. And for courses the lid is usually on the plotter.

I agree they look small. They said they were right but I will double check. There is the equivalent of about 10cm x 30cm do I guess the area is about the same.

The match is good. Take a look at the pictures of the transom repair and the polished bit is a completely different colour to the yellow, unpolished bits.

Maybe he said 30 total I don't know. Will ask next weekend when I see him.

Paul (VP):-
I think the formula for selecting the K&N's is CID x RPM / 20839. I used it to size my filters for my TAMD 63p's using the following data:
Cubic Inch Displacement (CID): 334
RPM: 2800
K&N advise the 20839
So
334x2800/20839 = 44.8 sq inches, I the selected the largest filter with a 70mm flange which was an RU-2940, which I believe gives you around 137 sq inches free area. So should be plenty big enough?

Mmmmmm mind you I note the ones Mark fitted are cone shape whereas the ones I have ar cylindrical...... Mark what filter did you buy?

Yes I agree they are big enough when 100% clean, but as soon as they start to block up there going to need cleaning, the surface area of the two paper element that are fitted as standard must be twice the size of the k and n filter, which leave room for error on the dirt size mid season, also the original filters are not a fortune, but hey who's counting, I bet hey sound nice when the boost kicks in!

cant count the area of both of them Paul, only 1. It passes through both, not the two side by side.
I had multiple reasons to change:
1 one of the bodies was cracked and needed replacing.
2 the volvo filters cost more for disposables than the one off K+N cost, on top of the cost of a new body.
3 I can now get behind the engines without taking the air filter off.
Taking the volvo one off is a pita, as the nuts aren't captive. The reason why it was cracked no doubt was someone squeezing by.
I am worried though about your noise comment. If they're noisy I'll swap back and weld on the nuts.

Not a weekend of great progress, the weather was getting me down.
I did wire in the bowthruster, and start fitting stuff to the dash. Working out the cable run forward took a while, and of course is a worthwhile time investment.
Also started re assembling the aft cabin.
Other than that it was just nice to sit on the boat and chill a bit.
Windows due back this week, once the injectors are back we can launch. That will give me new enthusiasm.

Paul, They are three times the minimum required for the swept volume and the path of resistance is also less. Given that the air load is very light it will be a long time before they become challenged and the frequency with which diesel engines are serviced, I am not expecting any problems. As far as attenuation is concerned, the material itself will absorb noise, compared with the breakout noise from the steel box that the Volvo filter sit- in I can't see that being that much of a problem too. Will let you know! I'll take some sound power readings before and after in the saloon.
If it is more noisy, it will only be an issue on a long run or in bad weather, in that case we will likely be throttled back anyway. Otherwise, we tend to spend most of our time under way on the FB!
It may remind me of my twin 48DCOE's, aaaaaah those were the days!.
