If these engines were in a lorry...I wonder?

Have a friend in the port with big engine problems (twin diesels). Both engines start losing large amounts of fresh water per trip (30-40nm)

Investigation reveals stb head gasket gone. Also find that the stb turbo is shot bearing etc requiring overhaul.

Then find port engine head gasket gone.......Now big coincidence methinks, that both engines have head gasket failure at same hrs about 500 plus.

Good gawd now discover the port turbo has gone same way as stb. Now that is a second HUGE coincidence dont you think? I strong letter to the manufacturers is called for.

An anyone think of why the two coincidences? is it just cos they are in a bloomin boat and not in a lorry?
 
Are they consecutive engine numbers?
If so they just wore out together.
Same happend to me with Perkins 4107s (the second worst engine ever built).
Engine 1. cylinder liners perforated.
Few days later engine 2. cylinder liners perforated.
Couple of months later,
Engine 1. head cracked.
Few days later engine 2. head cracked.
Month later engine 1. crank broke.
2 days later engine 2. crank broke.

Six months later, sold boat.
New owner forgot to turn intake cocks on, cooked both engines.
Full rebuild on both.
Where is Blue Maroy now?
 
Sounds a bit like a V.... and 42 series... if so, not too uncommon... Have seen a few of these gone ... cylinder 6 seems to be a weak spot... last one I saw had 600 hrs on the clock... and similar issues...
 
The turbos in my old S37 (Mercruisers) both went at about 500hrs. Fortunately they were fixed under warranty as I had only just bought the boat but the guys that fixed it didn't seem to think that it was unusual.
 
It's wierd, because the smaller KAD32's are running a higher bhp/litre, yet seem to have a better reputation for not blowing head gaskets and turbos. I had thought the KAD43's were pretty much "fixed", but it looks as if there's some sort of curse with the 42's and 43's...

Last truck I had, did 250,000 miles, without a spanner on the engine. Then I sold it.

Yes but, yes but, that's the difference between a good old Gardner (or even a DD), and modern Drof (and now subsidiary companies) products (I was going to say crap, but then there's no real need for that)

LOL
 
No, its because no truck owner in their right mind would buy a truck with a highly tuned supercharged and turbocharged engine like the KAD42 and expect it to last 200k miles plus
We boat owners are to blame for this situation. We expect our boats to do 30knots even if they're loaded up with useless equipment and badly fouled. Then we only use them 100hrs per year and we only care that the engines last until we chop the boat in for a new one in 2 or 3 yrs time. So, its not really a big surprise that engine manufacturers squeeze ever more power from engines and, as a result, they need a rebuild after a few hundred hours
 
I know what you mean. However...many truck motors do, in fact, find there way into boats (Ford 6 banger for example) and they do not fair well overall. Not as well as on the road anyway. reason?? Coz they are marinised and sea water and salt air just kills every bloomin' thing it comes into contact with.

The running characteristics are also vastly different. A truck motor works its plums off for hours every day, while the same motor in a boat just sits idle for weeks on end in all that damp nasty salty air in a damp bilge.

I'd still ahve a bloody good go at the manufacturer though. /forums/images/graemlins/mad.gif

not so in this case, well cant confirm the first 300 hrs before ths guy bought the boat but she has done 200 plus hrs in last 11 months mainly via us, so serviced regularly.

I was'nt gonna say but as there is speculation they are KAMD43's
These are the same as on my boat and it took 2500hrs befre one went on mine (head gasket that is)
