Fouling in the Med

[tcm]

Re: Props calcs?

true, cept the barnacles round out way seem totally uninhibited and love all surfaces. Or, the paint used on our boat is "foul" rather than "anti-foul"

Pleased to see that you mega yachties have the same probs as we lower forms of boating life.

Re: Targa 48 fan club

Trim tabs, and there are actually two, over there>>> go on>>> the other side of the bathing ladder. Is that the cut out you meant?

Re: Targa 48 fan club

Actually it was not at 32 knots then (if you take a close look at the revs you will see) but I was out on my own and took photo from table.

Carbon fibre is the grey stuff. There are plenty of firms do the wood or CF.

Every T48 I looked at with the wood had a problem. I changed the wheel to one from a Targa 52 cause I thought it matched the Carbon Fibre better, so if ever you need a new wooden wheel, I have one in my garden shed.

Re: Targa 48 fan club

1. Delete both spaces, one before the http and one after the jpg

2. Put a forward slash before the second image ie [/image]

Should work then

Re: Targa 48 fan club

Yes that was the space i meant. Very imppressed that the trim tabs are flush under the hull and not sticking out the rear of the transom like a sore thumb!!!!

Can i join the Targa 48 fan club,, I don't own one but i drooll every time i see one.

Can i play on your boat mister/forums/images/icons/cool.gif/forums/images/icons/wink.gif.

Re: Targa 48 fan club

Um, yes you're right. RPM seems to indicate a more stately 6 knots. Nice job with the carbon fibre but why didnt you change the rest of the dash?
I'll remember your wheel if I ever need to convert my boat to dual control

Re: Targa 48 fan club

I did'nt actually change any of it, it came like that out of the box, honest guv.

I suppose it would be good if the large grey area was also carbon fibre but I am not that bothered and hey, if it aint broke don't fix it.

Current jobs include repainting engine bearers and generally polishing engine room stuff.

Re: Targa 48 fan club

Had loadsaproblems recently. Port engine stopped at sea, problem traced to fuel pump after 5 days of engineer time, exhaust leaking again, passarelle now operating intermittently (any idea how you get to it?), domestic batteries knackered and it goes on

Re: Targa 48 fan club

Had to replace all batteries on mine. about 70 quid each if you go direct to what was lucas Automotive.

ENGINE PROBLEMS:

Following routine 100 hour service port engine failed to give more than 1650 rpm
Went on boatdiesel.com and found that engine management has a sensor which detects turbo boost pressure and allows engine management to fuel accordingly.
This sensor pipe becomes filled with condensation and eventually f***s the sensor.
Therefore no more fuel, therefore no more revs above 1650.

This sounded right so checked pipe and it had water, but also checked wastegate on turbo because diagnostics had reported overboost which would suggest that wasted gate was not opening as it should.

Wastegate was full of coolant (it should not be) and Turbo had traces. Changed Turbo and wastegate suspecting Turbo housing was cracked.

Put it back together but still nothing over 1650 so it looks like sensor on engine management had become faulty, Turbo had overheated due to overboost pressure. So now we still had to replace sensor on Engine management. Except you cannot. You have to buy the complete engine management system. swopped engine management over between engines and fault transferred with ems.

Bought new engine management system which now comes with replaceable sensor!!! and made my thoughts know to Volvo at Sibs. They will look at it and watch this space.

Took Turbo to excellent firm Turbo Dynamics in Christchurch to pressure test and they confirmed Turbo casing cracked

Back on water and WOT starboard engine down 150 rpm. Check wastegate on this engine and it has been set to boost too high. Take it to turbo specialist who confirms it has been set too high manually. I asked why and was told it may have been done to improve performance. As the engine management reduces the fuel it allows if it detects overboost this was a serious waste of time by someone. Anyway service waste gate from my old turbo and fit it.

The trip round to Swanage was the culmination of the last months efforts hence the euphoria.

It does go well now, reaching 32 knots with full fuel half water and 210 kg rib in garage but I will make a seperate post at sometime in the future regarding this experience and warning owners of Volvo 74p's to check for condensation in sensor pipe and to check operation of wastegate at 100 hour intervals which is apparently a Volvo requirement now.

Re: Targa 48 fan club

Wow and I thought I had problems. I was going to say it was the right decision to favour Volvos over Cats but I guess you're not so sure now

Re: Targa 48 fan club

Now about that membership!!!!!!!!!!!!! EEEHHH Forgert it!!!

Seriously Though, if you had the choice again, would you still go for the same brand of engine or something like the Cats instead?

Re: Targa 48 fan club

Nah, the Volvos are fine, I considered 10 grands worth of engine work when I made my offer to buy the boat and 130 hours later I may not be dissapointed.

If you get the Diagnostics reporting fine and you service with TLC they are great.

I like Cats but the bottom line for me is crossing the 30 knot barrier and with the largest Volvo's ie 74p's the brochure speed was 35 knots. As previously stated I think clean with half fuel I would still get that. Mike will say what the Cats will do but I think it is around 28-29 knots WOT.

I dont really have any issues with Volvo on any of this except that the sensor to the EMS has a design fault and I am confident they will stand by this because they have already made the sensor a seperate part to the management system, and they did'nt do that because it was working fine with no problems. I have around 20 Volvo engines in service on various bits of plant and equipment and we get relatively very few problems, with excellent backup.

Volvo parts can be expensive but things like Turbos and wastegates are actually made by third party suppliers so there is always an alternative.

I think marine service in the Med for new boat owners can be poor and many owners arrive at their boat generaly expecting it to work. They are not hands on like the Deleted User's of this world. They use it and then leave it. They think because they are paying someone to look after the boat the serviceing will be top notch and they dont really know when its not. I bet 99% of 100 hour serviceing does not include a wastegate check but Volvo insist that it has informed dealers, but how many of those notifications are sitting in the in tray on the service managers desk accumulating dust?

That is why I replied to the guy bringing the S37 back from the Med to get the Volvo diagnostics done, far better than oil sampling imho.
If you pick up an overboost from the diags then the wastegate is the first thing to be checked.

Re: fast targa 48

hm. can't agree with this c-j.

When ours was 5 years old, and with lovely med servicing on 2 x 426 hp Caterpilars, we had mometary 38 knots with the bimini up, and not too hard to crack 33knots or more with clean bum, light. The boat scoffs fuel at this speed tho and a good thrashing is not rec'd with any t48's i hear.

I think you may be right that some balearix boats skimp a bit. But not right to intimate that the servicing is generally rubbish in the med: there are few places in UK that can match southern french maintenence outlets - lots of mechanics with actual engineering shops rather than UK "little men" and the odd franchisee here and there. There are far more big boats there and a fifty footer is below average size, not one of the biggest as in the uk.

imho

Re: fast targa 48

I was going to suggest that 38 knots with 426hp was with the help of the tide!!
I would be interested to know what Mike gets?

Did not mean to intimate that all Med servicing is bad indeed SOF I hear can be very good, but what I was trying to imply is that you do not have the owner likely to appear at the end of the pontoon asking awkward questions about whether the wastegates have been checked or not! The engineers do their servicing job and the management team tick the box that says the work has been done but generally there is no one checking the little things. Maybe its just me but I feel that some owners idea of ownership of a boat in a different country is different to my idea of looking after a boat.

all imho as well
