What color is the excessive smoke? White or black?
If it's white you are either too cold or have water getting into the cylinders or exaust. If it's black the you are probably dumping too much fuel or not enoug air in on start-up. Or worse, you have oil gettting into the cylinders when they sit.
White smoke is pretty much normal for a cold diesel start-up and usually goes away after a few minutes of warm-up. Black smoke otfen inbicates worn injectors or gasket leaks, restricted air flow or internal issues.
If you have long crank times at only 55 degrees then I'd think fuel delivery issues or air fuel mixture issues. Maybe fuel pump pressur, bad air intake or worn out injectors.
At any rate, I wouldn't mess with this too much longer.
Call Mann and find a good mechanic to get this checked out right away!
The small fix is likely a lot less cost than the big fix.
I just plugged in the block heaters today. i going to try start her up tomorrow and let you guys know how it goes
If you think you need a good MAN mechanic the guys at Bayside in Mystic, CT are very honest good people to work with. Also, I have heard good thinks about Scott Marine they serve both NYC and Florida. Good luck.
well guys, i went back to the boat this evening and the heaters had her nice and hot..and they started right up with no problem. Thanks a lot guys for the help
So are these engines designed to need a block heater for routine starting or is using the block heater compensation for some problem that's not being addressed?
If they started with the heaters on they you likely have fuel pump pressure or clogged injector issues.
There is a product out there called Diesel Kleen (Silver bottle) that's bvoth a cetane boost and an injector cleaner and fuel lubricant. Go get you some and add to your fuel per instructions on the bottle. Run them with this and run them hard a few times with it in the fuel.
Also, try a different source for your fuel.
Then try cranking again with new untreated fuel at low temps. If you have some luck this will clean you out and you will see a diference in cranking after the treated fuel has been run through.
My diesel truck runs this stuff all the time after I figured it was sensitive to fuel bought from some stations. My experience is that the quality of the new low sulphur diesel varies a lot and can make make a significance in diesel performance. Diesel Kleen has largely solved this issue for me.
Don't mean to try and sell this product here, only relating my experioences. There are other brands of fuel treatments that do basically the same thing. However, this product is pretty much available everywhere, including at almost auto parts stores and Walmart.
I still think you need to talk with Mann and inquire about you situation, partucularly in regards to any effects you might experience with the new low sulphur fuels. There were some highly suspected issues with certain high pressure fuel injector pumps and certain types of injectors wearing because the initial low sulphur fuels didn't have the same lubricating properties as the olde fuel.
Still think you need at least to talk with Man. But am not familiar specifically with their specs or any issues.
The long crank times at really not low of ambient temps and smoking after start is still a concern and leads me to believe you might have fuel pump pressure issues or injector issues where you arent getting the fuel mixed right in the cylinders.
That can have a long term effect, particularly in regard to engine and crankcase deposits that need to be reasonable to insure you get the full longevity out of your engines.
If you have such issues you often will get unburned fuel in your crankcase oil, which can be a serious issue for lubrication of thye crank bearings and cylinder walls. Effectivelythis dilutes your engine crancase oil and makes it "thinner" than it should be, thus not protecting the engine parts with adewuate lubrication. There are lubricatiing oil testing services that can test your crankcase oil for fuel dilution and other possible issues that you bprobably need to be doing. The outfit I use is Blackstone Labs, but I be willing to bet that Mann offers this service... know that Cat does.
For what you have invested and the cost of major rebuilds or replacements, I'd be more concerned than you appear to be.

Guys, turning on the block heaters solved the problem...she starts right up now..theres no fuel or injector problem.
Let me say it again:
So are these engines designed to need a block heater for routine starting or is using the block heater compensation for some problem that's not being addressed?

in speaking with the former captain..he informed me that anything 50 degrees and below, the engines will not start unless they have the heaters plugged in and its been that way since they first put the new motors in 270 hours ago

I could understand if it was ten degrees, but fifty? Suppose the boat was on a mooring? You could only start it in the summer.
Ron...same thinking...my boat sits on the mooring 200 feet off my dock instead of on my dock if I have full fuel as draft can get iffy...spring and fall, the engines do get below 50 degrees...if i had those engines, I would be screwed...something has to be up....

If the company's engines needed electrical block heaters to be started below 50 degrees, they would have been out of business long ago. Even if the engines have been this way since they were installed, there is something wrong and something that can and should be corrected.
