In the same hrs approx 600 over 6 seasons with MAN s I have only had one sensor let go , which was not a show stopper .

Porto - You seem like a nice guy, but take the blinkers off - all engines/boats have issues, some more than others, compromises are everywhere. Its about the right set of compromises for you.

This is your post below about the exhaust on your man - it all looks pretty rusty to me , and how long did they last from new if you needed them repairing in 2014 as part of the negotiations to buy the boat.

Ref Pershing 37 above, it's a nice boat but...

a) the accommodation is even tighter than our T34
b) the shafts will burn way more diesel
c) you'll be struggling to find people to repair it
d) everyone in the UK will wonder why you didn't but a British boat

That'll be another 'No' then'. So to summarise....

You don't have any proof that heat is a contributing factor to ECU failure. And you don't have any proof that KAD ECU's fail any more frequently than those of other brands.

Yes my Fr engineer , did you miss that ^^^ .
I nearly bought a boat with 74 p s in .At the time at Cannes the Villanova bro’s ( based in P Grimaud/ St Trop ) we’re the importers .I knew one from Ferrari club activities going back a long time .
He took me over at his stand @ Cannes put his arm round my shoulder and whispered “ buy a CAT “ “ not Volvos “ or words to that effect .
A chuffing boat dealer flagging em Pete .

Later on indeed a VP powered version rocked up a few places down from us in La Nap .It’s engine hatch was always open and the pontoon littered with pretty blue boxes every season .


@ Julian’s re bulkhead mounted ECUs ……..wonder if thats only a windy thing .They uphold an enviable rep ??
You know Windy asking VP to do it differently so it’s fits there brief ?

Apparently there is strict divide in the industry of where the responsibility from the engine manufacturer ends and the builder starts .In terms of exhausts it the flange , the turbo flange .

Elbows and pipage , etc are the builders responsibility , so I was told .
2003 fitted new , pick up at my inspection, then rectified but only welded up so on thin time line .Anyhow they did another 5 years or so .
Anyhow I had them as the post infers completely re done in S Steel + heat blankets added .Ok long overdue hands up .
The heat blankets work very well btw glad I opted for that .
Also a lot of ancillary pipes and clips + miscellaneous replaced , but as said all this stuff is technically outside the engines manufacturers remit .Anyhow just general keep on top of stuff .
Like I had the sea cocks replaced in2015 , nothing wrong just fancied trouble free boating again certainly no reason for me to knocking on MANs door , although I think we can all agree they are not the manufacturers problem / responsibility ?

Sorry Pete no stats or evidence, just take my word the manufacturers responsibility ends at the turbo exhaust flange .


Obviously with OD and IPS I would think VP are responsible for the whole lot as a unit inc associated exhaust pipe age running through.Let’s not drift into apples / pears . ;)

Your boats not in the U.K. it’s in the Med Pete .

d ) Did your dad buy BL cars in the 70 s ? Further More did you follow his footsteps in the 80 s ? :D .Sorry I ll get my coat .
No need to answer .

Just debunking the go to VP for a 30-40 ftr .
Then you have a Fr merry Fisher stuff as well sans VP .

That'll be a 'no' then. I do recall someone saying that the ECU is attached to the fuel filter to get some cooling from the fuel. I'm not sure if it's true or not.

It’ is true that’s why it’s there .
Kad 44 and 300 do have a rocker gasket it’s just not available any more

Gotta love this thread:

Q - What's best - Volvo vs Yanmar?
A - MAN

On the basis that the question refers to VP and Yanmar, that would imply that the interest level is with boats in the 30ft to 40ft range. I'm pretty sure that zero MANSs were fitted to boats in that range and therefore a somewhat 'left field' answer!

However, I do also believe that large CC, unstressed engines are the way to go, it's just this wasn't (and therefore isn't) an option on a lot of boats.

You're doing this all wrong, here, let me help.

I hope your dad didnt buy lancia in the 70s as fiat destroyed that brand. There were ALOT of crap cars in the 70s. 60s meanwhile Lancia were great and BL produced the iconic mini.
 
2x 140hp, 2x 250hp, 2x350hp yanmars over 20 years virtually no issues, 1 sheared bolt holding an alternator on a 140hp in about 1993 from memory and a start up smoke issue on the 350's all sorted.
Tamd 75's for past 9 years ,ECU issue and a couple of broken brackets, not a lot to choose between them but Yanmar are pretty good and would definitely have them again, very good support from Barrus in my experience.

PeteM will be along soon saying you are imagining the ECU issues , demanding evidence etc :D Proof you had a recent sanity test .:D.

As said thrashed the 5hit out of Yan 1 GM and my current Yan in the geny just won’t bust .
Ok only 10;Hp and iirc 6 Hp respectively but no £/€ on repairs ever .

Read somewhere the smaller Yans were designed for paddy pumps .Millions made .The thing is the three rings around the piston(s) .Apparently there are rings and rings in terms of metals and shape .Also the bore material is as such they last for ever with 5hit oil , in 5hit conditions- read never changed , continuously running .
Something along those lines .Basically you can’t wear them out .

If some fool changes the oil annually then that” fool “ is stuck for life with the Yan .

Wether that philosophy has migrated up the cubic capacity range - longevity in harsh unloved conditions like damp fields remains to be seen . Suspect so .Anyhow bodes well .
 
Yanmars are good motors but, as already mentioned, pricing for parts is absolutely eye watering - we have them in a couple of boats at work and we have spent a huge amount sorting problems on one of them. Some engines are the same as used in the Toyota Landcruiser so if you can identify what you need there may be cheaper options. They are also finely engineered so no scope for anything like a re-bore should a re-build be required. A boat local to us had the misfortune of both engines going pop and whilst re-builds were achieved it took a lot of effort and the use of parts from Toyota to avoid the exercise being cost prohibitive. Mind you, we also have friends who had a problem with a VP D6 and sorting that was also eye watering, not least because the engine block is one unit and there was no option to go looking elsewhere for parts.

I am genuinely interested but I thought that it would be a fun debate to instigate too. That size of boat is where I'm at. I know from the industrial angle that MAN make great engines so I left them out. Similarly Cummins make great commercial engines, equally Iveco. I also didn't mention Ford, Perkins..... as they are on the whole older. That said, modern Perkins diesels are excellent.
We see it in Agriculture all the time where they are tweeking 4 pot engines up to ever higher horsepowers, but a good 6 pot with a tonne or torque will always outlast and out perform the smaller engine.

a) the accommodation is even tighter than our T34 - TRUE although outside she is much better. Cabin version is not that bad.
b) the shafts will burn way more diesel - yes but a lot less headaches if any, cutlass bearing every 10 years, drip-seals same, rudder servicing less to 5k every ten years
c) you'll be struggling to find people to repair it - don't know I sold an Intermare with Yanmar in December in delivery I had a raw water pump go, no struggle at all to find people in nowhere land in West Sicil, six hours I was on the go. Also true though that Yanmar parts take longer to have then most Volvo parts
d) everyone in the UK will wonder why you didn't but a British boat - she is a Pershing (equivalent to a Porsche of the Sea), definitely not a boat for Britain and its nice cloudy weather, but so is a Targa. I never had a problem in selling P37, but I am based med in a British dominated by the large brands (Cranchi-Fairline-Princess-Sunseeker-Azimut/Atlantis). It also true that British is very closed minded boating wise, possibly even worse then Malta.

Wandered into the club house got involved in a discussion on engines.
Was told in no uncertain terms that Volvo, Cummins, Caterpillar and Yanmar were absolute rubbish, but the folks who actually had those engines in their boats declared them to be paragons of long term reliability.
Me I like Perkins but will put up with something painted any colour under the rainbow if it gets me a bigger newer faster boat :).
Still looking for new boat, BA. in the UK.
Do like the Azimut 42 its just the 20% B***** import tax thats screwing any purchase and it got stairs.
UK boats were so far behind the curve on designing boats into the 19th century let alone the 20th ?
