The boating industry overall has this attitude, if it's a part for a boat the price is double, you should see what airplanes are like!  Even worse.
I now have everything prepped onboard to install the new turbo and elbow, swapped out my air cooler with my spare, it was oil and soot contaminated and needs another good cleaning even though I only just installed it last year.  I keep spare coolers for everything then rebuild them at my leisure and box them up and into my shed.  I swap them out every two years weather they need it or not, same with my raw seawater pump. 
I'm held up waiting for the main turbo to exhaust manifold gasket and replacement nuts bolts and studs, some copper crush washers for the oil feed and return lines, I really hoped they would be here today but no luck, looks like next Tuesday will be my next best chance.  My mail lady pulled up and stopped in front of my house and brought out several small packages as I watched her she looked up and said sorry nothing for you today.  Darn it! I was all excited.

All these parts are made by the same companies.  I tried to use the Toyota PN to order my timing set.  They emailed me back asking for the VIN on the vehicle this was to be used on.  I responded that it doesn't matter what a I do with it.  They emailed me back sayiing my order has been cancelled.  I was stuck and had to order the Yanmar Parts, which arrived and all packaged in Toyota labeled plastic packs.
So yes absolutely they get you coming and going.

That is so rude. If you have the part numbers, maybe see if partsouq.com has what you need - I buy a lot of parts from there and they're cents on the dollar compared to buying from the local dealerships, even with shipping from Dubai.

Shipping from Dubai might make it cost prohibitive. But I'll take a look at them anyway.  I have had instances where I ordered something from Europe with shipping and still less than I would have paid from Yanmar.

I ran a pair of diesel Volvo's in an old Blackfin years ago, it seems Toyota has been to  the Swedish school of parts pricing.  Two groups of people became very important to me.  The "real" auto parts pros, people that have been at the counter for years, not the pimply faced kids selling air fresheners at the chain stores.  Brought in my pricy Volvo air filter, he disappeared with it and returned a few minutes later with a Fram, wrong color scheme, but a fraction of the cost, oil and fuel filters too.  The independent diesel auto mechanic, back then my guy was primarily a Peugeot guru.  Today maybe a Benz or VW specialist.  They know the little independent shops two states over that do injector rebuilds or square away sick turbo's, and maybe have an old housing you need in the stockroom pile.  It doesn't hurt to show up at ten to five with a cold twelve pack.  The injector guy loaned me a home made tool to remove the injectors, Volvo thought the same tool albeit a little prettier was worth a grand.  I gratefully returned it, with the injectors to be rebuilt, in a box including a few etchings of dead Presidents.  One last thing, a pre go Checklist.  Compared to the old diesels my new one running the etec's is pretty short, fuel, oil in tank, engines down, go.  Good Luck!

this single engine is all I can keep up with and ive not been doing a great job of that it appears.  I can only imagine having to do everything twice, especially paying for everything twice, Ive read stories on boatdiesel.com guys with dual engines, same model as mine and same exact problem. 7K to replace turbos, plus mixing elbows and all the little things that go along with it. I have concentrated on the raw water cooling system, keeping it pristine I even installed the new mixing elbow just 4 years ago expecting it to last for ten years trouble free and I ignored the turbo, even when I noticed excessive rust starting to build on it, I thought well it is 14 years old but the elbow is new so cant be a problem there.  when I noticed my RPMs were not where they should be I thought it was a prop issue and repropped the drive dropping 2" in pitch to get them back up.  Glad I kept my old set of props now, I may be putting them back on.  a major misdiagnosis and completely missed the real problem.  If I had installed a pyrometer and a boost gauge I would have seen the problem when early on and likely would have saved the turbo. I still haven't found a good place to mount a gauge for them but I am looking at reconfiguring my console to make room.  its a tight area with a lot of things cluttering it up.  Its a painful process especially to the wallet but I am consoled by the fact that I did discover it on dry land, in front of my house and not 50-100 miles offshore I am safe and nobody was injured or lost at sea. I can fix it at my leisure and not once have I felt the despair of wondering if or when help might arrive.

..."not the pimply faced kids selling air fresheners at the chain stores". HA! I love those kids, but only for the entertainment value. "Sir, my computer isn't telling me which part it is..." Here we have Napa Auto Parts guys that are moderately good, but the writing's on the wall as there are 2 new chain stores right next to each other! What kinda business model is that?

David,

You can get remote sensors that are bluetooth and monitor them with a pda or phone. What you mentioned will work too.

maybe it is time to yank out that yanmar and put in one of these fine tuned workhorses

doesn't look real comfortable for nasty weather but sure would save money on parts. probably swap out the entire engine for the cost of one turbocharger.

If you are gonna go this route, get the real thing:   http://longtailboatkkk.com/

If you have a neglected lawnmower lying around, you can just buy the kit without a motor.

Be prepared to lose you hearing.

that is a cool little setup, I do not think I want to go 50 miles offshore in it but backwoods swamp donkey hunting looks fantastic.  not to many swamps out where I live though.

 I have the new turbo mounted and primed with fresh oil, the new wet elbow is installed, the fresh air cooler is on, the intake air box cleaned serviced and new filter element.  fresh oil and filter, fresh coolant, all hoses and lines in place.  I am ready for start up.  Im concerned about the levels of soot I found in the throat of my intake manifold and the soot I cannot see that is in the combustion chambers and exhaust manifold.  Soot that I cannot easily do anything about.  I tried to consult with a yanmar specialist but I have been unable to speak with anyone knowledgeable as of yet.  From everything I have read about this very same kind of failure and refit I think I have done everything reasonable and prudent.  Many people just swap out the turbo and elbow and call it good. swapping out the soot contaminated air cooler and cleaning and servicing the air intake box and pipes were an easy extra for me.  I have a full set of coolers for my engine and I service and clean and test them myself then box them up and store them.  Every two years I swap them out and repeat the process. It takes me all of about 20 minutes to remove and replace the air cooler. 
I am going to proceed with firing the engine up later today. and see how that goes. 
I might just be a nervous Nellie about the soot but I don't want anything to break in my engine, that is one thing on the boat I cannot afford to lose.

She's up and running, engine sounds really strong.  First launch next Saturday.  Work is still getting in the way of my fishing.

Coooooool! I wanna be on a boat way off-shore with a details oriented, workin it close to perfection-captain like yourself. You never know, on a commercial boat once, the steering broke 10 minutes after launch and we never made it outta San Diego harbor(good thing I guess) till the next day.
