Mr Googler

i gave it one coat…..then put greasy hands over it.

Is all of this work necessary or are you just going to town as the engines are out of the boat. How did they run when you got the boat.

Ran ok but given the history and what I’ve found….I think it’s all been necessary ?

Totally agree. So much easier to do it all now than when engines back in.
piece of mind for sure

I would agree with that but most normal Mortals would not I think have the skill or bottle to do this type of work themselves so would be facing a massive bill

i have neither skill or bottle but google and the forum solve most issues ???

It is not as difficult as you may fear. A marine engine is essentially just a big diesel engine with some heat exchangers bolted on. Once you take the heat exchangers off they look a lot simpler. Many years ago our first boat had two Ford Mermaid Marine engines and they used to do a two day training course, which I went on and it all became much more understanderable. People are also a bit wary of the KAD series of engines because they have a supercharger as well as the turbo. But again, if you just ignore the supercharger and you are back again to a big dumb 6 cylinder turbo diesel. A good socket set, a torque wrench, the engine manual for settings and spanners and most jobs are straightforward as long as you take your time, stop if not sure and check and don't rush things.
The hard part is the engine is usually buried in a boat with poor access.
If you are ever tempted to have a go yourself, there is loads and loads of experience on here for advice and the best/easiest way to go about a job and where to get the bits at best prices. If you can change your own oil and change the fuel filters bleed the system etc, then I am pretty sure you could pull the turbos and heat exchagners off and do any valve adjustments too.
However outdrives are the work of the devil and specialist tools and real in depth knowledge is needed to get them right.

Absolutely spot on….unless I can’t put these back together……then you’re wrong ???

My problem is that I just haven't done enough 'wrenching' over the years.
So I'd end up rounding off bolts or snapping them, bending fuel pipes, breaking lugs off pins / connectors, etc. Not to mention lacking the basic skills to re-insert o rings gaskets, etc.
I'm goof on all the theory though and am happy to tell someone with the skills what to do.

Jumping up and down on a breaker bar gets most things out ??
Ive actually completed something! Descaled, rubbed down, rubber mounting rings cleaned of paint, sprayed, reassembled with new seals. The eagle eyed will spot my new turbo….s bottom of that picture. Love a new turbo ??
Just another 300 jobs to go….then think about the boat itself.
Found a peach of a fix on the hull. Transducer wasn’t working so previous owner asked for it to be removed and the hole filled in. From what I can gather….This was down with 2 thin fibreglass plates, EXPANDING FOAM and a bolt straight through the lot as a clamp. I can pick bits off from the outside!
All being cut out and done properly obviously now but it’s bloody scary. Stupid fixes like that could be a boat sinker.

Good job!
Like I said, best thing to happen to that boat. Pleased that it's in safe hands.

I trust you're going to paint the Turbo?
Mr Googler

Yes….I saved 1k on each as they weren’t painted Green on arrival ?

That green paint can be MIGHTY pricey……

you mean expanding foam is not a seaworthy/certified marine building material?
check carefully allround, bound to find more...
I hope you will remove the outdrives as well, you may find they're sealed with bathroom silicone!

Head skimmed!
Video below for those sad like me who like that sort of thing
Head Skim
Only a very light skim required. Just under 0.15mm taken off. The engineer said…
“Very light considering it’s size Average head skim for a 4 cylinder car engine is 0.004 - 0.008” / 0.10 - 0.20mm, for something nearly half the length of yours”
