Engine: Yanmar 6LPA-STP2
Hours: 800-850
Age:
I'm contemplating tackling a couple of jobs and considering doing them myself.
Here are some of my thoughts on why I think I need to move in this direction. I bought the boat about 8 years ago. At the time I had the engine surveyed. Everything was great.
Exhaust Elbow
Cast iron elbow looks original. I'm just going with, I assume this is necessary preventative mainenance.
Heat Exchanger
When I first bought the PO had been using teflon tape on the threads of the zincs for several years. Also, I didn't realize I had been missing one of the two when I was changing them yearly.
As of right now, I keep filling my overflow reservoir and it keeps emptying. Very slowly, but it's happening. I suspect i'm leaking AF into the exhaust water discharge.
Clean Turbo
Fuel Injectors
Lately, I'm getting a decent puff of blue/grey smoke in my exhaust at start-up. The engine also seems to be putting out a lot of what looks like white steam when running, however it definitely has a string diesel exhaust smell.

No idea when the turbo was cleaned last. I'd guess never. The previous owner and I both run it at around 2400. 3200 is WOT. Turbo IS spinning, I can hear the whine.
I'm guessing the exhaust issue is likely either Turbo or injector related.
Questions:
1) Are these doable as DIY for someone who is reasonably able to do mechanical things (Hip bone connected to the leg bone, and I can read absorb manuals). I work in a highly technical field.
2) Am I on the right track with my thinking regarding these issues?
I'll be happy to open a parallel thread to discuss the technical aspects of a specific item if we end up going in depth on any one of them.
