Are you suggesting this is a success story!

I am.

LP were indeed in dire straights as were Deutz in the mid 90's. Lister had the x series (which are the D2008/9/10) but could not afford to put it into production. Deutz needed those modern engines to replace their older models. Deutz bought the X series, the money paid to LP left them with no debts and allowed them to get a fresh start. Both companies did well out of the deal it was a good deal.

I have no idea how LP will end up. Deutz are currently doing well and they are very good engines. I have never suggested that anyone should buy LP engines. I did mention that Deutz mid range engines are listers. If I ever have to replace my HRW6M It would probably be with a Deutz.

But in answer to your first post.

Deutz have never purchased engines or technology from lister, why should they.

I was just pointing out that not only did they purchase Lister engines they bought the whole R&D set up for quite a large sum of money.

Why not look at the problem this way?

You have a boat, possibly with a knackered engine.

Ask yourself the following questions?

What space do I have to fit a new/different engine?

What engines are available to fit my requirements?

Do I need to buy old or new technology?

Can I fit any "new" engine into the available space?

When you've answered these questions ~ You'll have your answer!

Hello Refueler,
"are they all Cr*p"? - Yes!
However, if you make thousands of cr*p engines you are sure to get a few good ones.
A three bearing crank was a very bad design idea, which is why they break so frequently, plus the heads that crack regularly. I suspect that many 4.99s, 4107s and 4108s that are supposedly running "sweetly" have cracked heads that their owners don't know about!

Please note this is not conjecture, I am speaking from bitter experience!!!

It is not all Perkins that are bad, only all the 4.xxx range.
Everyhing else is first class!

I would rather have a knackered Yanmar than any Volvo!
Not including commercial Volvos which are a totally different animal to the small boat screamers!

Rant over, I'll go and lie down now!

Well we must have another of the good one's as ours chuggs away sweetly, even pushed our 18 tons most of the way across the north sea once and never missed a beat !

 

[Refueler]

Well I'm a long way from a Perkins Dealer ... there's a service agent who charges mortgage figures for anything .. but he's not true Perkins guy ... but still I'm happy to chug away with my 4-107 ...

When it dies - I'll see if I can find PCUK contact in the ancient archives to let him know !!

Be wary of Petters which had the combination of raw water cooling and aluminium cylinder heads, award winning designs when new but all old enough to suffer corrosion by now

If you buy a new engine you will get better efficiency, better power to weight ratio and better spares availability. You will have less nostalgia, less smoke and less downtime. In summary, you are likely to have fewer problems with a new engine.

As for the power you need, and the specific engine, I would first talk to the Owners' Association and take advice from others. However, if weight isn't a big issue for you then consider a more powerful engine. 100hp is not unreasonable for a 15m cruising yacht. I have 110hp in a 12.75m yacht (NOT a motor sailor).
