They are corroded. But believe it or not they spun freely and had very little shaft play. But they still donít look very healthy. I might ask them to hook up a boost gauge if the injectors donít solve the problem.

Smoke no go...

What color smoke after reaching operating temps? Old fuel can certainly degrade in the tanks, freshened injectors are nice... A compression and leak down test on the cylinders is easy and tells a lot, a good diesel tech can also check boost output of your prospective turbos as well. The IP can be a source of power loss, hard starting and smoke too... Agree with you, let em keep changing nice bits that you would be on the hook for.
Speaking of on the hook, the "Fish House" restaurant at mile marker 102.4 has always been a favorite of mine!

Buen provecho

Unless the props are damaged, they're the props that have been used and not likely the issue. It's more likely an engine issue of some sort. It may be minor and it may be major.

They tried to make rated RPMs and did not achieve that. And in conjunction with attempting to make rated RPM, there was a lot of smoke. If that smoke was black, then the engine is overfueling(overloaded)...which is likely caused by props that have too much pitch. This boat with these engines is not likely operated at a point where the engine would be overfueling. They probably operate the boat somewhere in the 1800-2000RPM range and at trawler speeds....which would not likely cause the symptoms mentioned. And I was not refering to damaged props. But to props that have too much pitch. And like FF stated, these particular props and engines may be perfectly fine at those RPMs. And like the OP stated, black smoke could be caused be a lack of boost from the turbos...but admitted they spun freely and firmly.

Poor Injectors would cause white smoke and likely be present at lower RPMs as well.

Black smoke generally is a sign that the engine is overloaded....or is not getting enough air(clogged intake or poor/no boost).

We will see. Answer would be easy if we knew what RPM he was achieving before.

It would also help if we knew for sure what color smoke. It was never mentioned but I made the assumption.

Many unknowns with this boat. I can walk at any time, so Iím not on the hook for anything. Iíll get more information next week when they sea trial it again. This time the broker will go with them.

I donít know if thatís true. I keep hearing the 185 have aftercoolers. I also have to wonder about just bypassing the intercooler if it goes bad. Itís more complicated than itís just now a lower hp engine.

I got that info from Bob Smith who was VP with Lekman and started American Diesel during a class on the Lehmans. He was the ultimate guru on them.

Yes, if it is on the internet it must be true... Bob told me the one thing on my engines that was not available was the intercooler. He said that if they go bad I could just run a hose to bypass it and then I would have a 185 instead of 225.

Yeah I believe you. I just donít know why I keep reading otherwise. I keep finding they say they are aftercooled. I believe aftercooler and intercooler are the same thing.

Aftercooler and intercooler are interchangeable terms in most peoples minds. There may be some technical difference but if there is I donít know what the difference is.

My wife and I live on a 45' Sea Ranger Trawler. Everyone thinks its 50' plus but its not. 15.5' beam. 2 Cabins and an office. Plenty of room but if I had the chance when we bought her, I would have gone bigger now that I am on the Crazy Monkey2. Next boat will be 55' but for now, this is perfect.
