How does the Volvo Punta D3 rate as a boat engine . ?

Since starting another post here I have stumbled across some research on the Volvo Punta d3 diesel 190 HP ; . some have been very scathing in their appraisal of the engine . I have come across the comment '' an engine made to last 1500-3000 hours . a disposable engine ''
It has been suggested that Volvo knew that this particular was NOT a success and they paid off any complainant just to shut them up. Then there is the '' anything- but- a. -Volvo d 3 school '' these people are so vehemently anti D3 Volvos that when they go to ''power -up'' ( by which I take it to mean replacing the engine with a more powerful one ) that they will NEVER install a Volvo d3
With all this bad press raging on many forums I stumbled across I wondered how a company as reputable as Volvo could possibly have compromised their good name by producing a flawed engine .I am illiterate with regard to engines - and it is to my own embarrassment that having owned 6 different diesel powered boats , I know nothing of their workings . Equally guilty am I regarding cars - I must've owned a dozen different cars and never understood how they worked ,
But I digress . Does any one out there have evidence to refute the appalling reports I am getting re the d3 engine .
If it were true and these engines are unreliable ; constructed with inferior material ; unsuitable for boats ; have a life span of 1500 -3000 hours max - all of which arguments which have been very stridently articulated , I would have to consider replacing the d3 in my regal 2565 .
Knowing as little as I do about mechanic and given my age I need to have a craft whose engine is manageable and repairable by an average mechanic .
That is why I took issue. With the EVC v older engine construction debate . Are we any better off with smarter engines -? ; see the thread - some excellent contributions .
1
Is there evidence to suggest that Volvo installed inferior metal or inferior other fabricated parts just for economic / greater profit reasons ?
2
Is there evidence to suggest that d3 have a shorter shelf life than engines of their ''cohort'' group - a working life as short as 1500 hours ?
Is there any evidence that Volvo adopted a ''disposable engine '' attitude towards this engine .?
Some of the articles/posts written about the Volvo pent d3 are truly horrific .
These are either grouches, malcontents or slanderers .
I would. really appreciate any feedback from anyone with any positive or negative experience of the Volvo Punta d3 diesel 190 hp marine engine
I have sent my concerns along to Volvo pent just yesterday ,and I will report here any feed back .
But lets invite people to vote on an evaluation on the d3 - Is it even it the top ten engines of its class- ie engines for express cruisers , and where would it sit on a scale of 1-10 on reliability .; trouble free motoring , ;and engine durability (or half life ) ,; repairability
I must add here that I came across all this v worrying criticism of the d3 while NOT looking for. It , It is out there . It is all - stated in uncompromising unambiguous language and there was not nearly ( less than 20 %) who spoke favourably about the engine .
 
They seem to work alright in the V70/XC60/XC90 cars so the engine block and internal etc are ok. I think the bit that falls down is perhaps the marine electronics. All the issues I have heard were from a period 2006-2009 and to be honest very little since.

I know of several boats with D3 engines that are running fine.

As for being limited to 3000, there arent many pleasure sports cruisers that get any where near that. even 1500 hours in a light weight soap dish is probably 20 years + of boating based on average usage.
 
Virtually all engines let loose on the marine market tend to develop a reputation for having problems of a greater and lesser magnitude.
Volvo possibly gets a regular pasting possibly simply due to the sheer variety of engines they have produced over many years.
Doubt any manufacturer deliberately allows a less than reliable engine on the market.
Problems will always manifest themselves after some time in use,sometimes due to the use to which the engine has been put and sometimes due to less than perfect installation by boat builders.
My old VP 40A. apparently had a reputation for valve seats dropping out of the head. ?
After I had sold the boat with over 4000 hours on the clock and nary a problem, always enthralled by the number of people who told me that particular engine was a unreliable pile of ****.
There are probably tens of thousands of them soldiering away along with the old Perkins and a host of other unreliable old smokers.

It is interesting that Volvo Penta's own website states (regarding the current D3)

Volvo Penta’s new D3 has been developed using the latest available engine technology. It only has the name and number of cylinders in common with the first generation D3.

It does seem that they are keen to distance the current D3 from the original offering for some reason...

Are you having repeated issues with your D3? It does seem an extraordinary amount of trouble and expense to go to otherwise if your engine is performing satisfactorily.

Not sure I would agree with that, have a chum with a Volvo franchise, when mileages get over 60k reliability on these cars is frightful.
 
Not commenting on the engineering, but there was brief fad in the Uk that USA (sportsboats) boats really needed a small diesel. Never understood that as small sportboats are great with petrol engines. Anyway, I think a number of criticisms of the D3 in such boats really was that they were a lousy option for what is supposed to be a whizzy speedster; that might do 50 hours a year.
D3 190 in a 2565 seems miniscule unless on a river IMHO.

Does it?

Loads of similar sized boats running single KAD32 engines (170hp), Sealine S23/S25 for example, Sea Ray 240 Sundancers, etc etc.

Would seem an entirely appropriate engine to me.

suggest you wash your mouth out before referring to early D3 as being in the same ballpark as kad32
 
Ha! I'm talking in terms of performance only. If 170hp is plenty for a Sealine S25 I can't see how 190hp from a D3 is going to be only suitable for river use.
 
VP only marinise the engine, it's actually built by Volvo Cars. The original D3 was replaced by the new D3 as Volvo cars stopped producing the old version, by this time most of the early faults had been rectified.
 
OK, but if I bought an USA sports boat I would hardly be looking for sea line 23 25 performance. My response was a question as to whether fitting cheap...yes cheap d3 lead to disastisfaction as opposed to coughing up and getting d4 with some grunt.
But if someone is happy with a d3 performance in 26 ft boat, all fine with me.
 
The D3 is a light duty (car) engine. The vast majority of marine engines are heavy duty, some from trucks, some other HD applications. In a car the duty cycle is relatively low, with max torque normally less than 20% of the time, and for cars that spend their lives on motorways, even less than this. With a planing boat you spend much of the time at 50%+ torque, much higher duty cycles.
However there are some on here with good D3 experience like Bart.
 
I have a friend with a D3-160. On the data sticker with serial numbers etc it also has "useful life 10 years/1,000 hours" which is nice. Its a 2005 boat, when I saw it I thought it was a silly thing for Volvo to put on an engine, unless it's just so they can walk away from it completely after 1,000 hours.

It's inky done 250 ish hours
 
That refers to the D3 is expected to satisfy the existing pollution standards (when produced) for 10 years/1000 hours, not to break down after 1000 hours.

Thank you Skipper G perfect summary.

U.S. EPA certification notice on engines causes lots of silly confusion, simply means that after 10years/1000 hours engine HAS to meet all original certified emissions levels at the power/rated speed listed in the EPA docket # for that specific engine rating.

I was not going to bother getting involved in this one as people seem to have little comprehension regarding the difference between durability and reliability.

In this day and age an LDA (Light Duty Automotive) will give greater life to overhaul (true base engine wear out) than a pleasure boating application will ever reach in a useful life of say 20 years. After 20 years of marine age the marine hang on bits start start to question engine financial viability.

The comment 'disposable engine' comes from engines parent bore design. I have a real liking for 'parent bore' engine design pretty much all LDA engines as well as VP D4/6 and later Yanmar LYA engines have no service oversize enabling cylinder to be bored. Sadly piston pick up due to coolant circulation issues are not uncommon with marine marine engines. Pick up a piston on near new engine due to leaving sea-cock closed, another 'disposable engine'.

VG turbomachinery has no place on on steady state marine diesel engines, they are a built in 'unreliability' factor, do not blame electronics.
