hard start

[Shellback]

i am looking at a 2009 Ranger 25. It takes three tries to start the QSD 2.0 engine After running a minute it starts normally. Any advice...

Does it smoke after starting? Is it turning over slowly like a weak battery? Does it have good fuel and fuel filter?

No smoke. Battery's full charge. Fuel and filter good. Filter changed last fall at decomishining.

Glow plugs ?

Try using the parallel switch to combine both house and starter banks. If it starts in that configuration then the starter battery isn't supplying enough amps. The engine has to turn at least 170 rpm or the ECM will not initiate fuel injection. When we bought our boat we had starting problems. After much hullabaloo the problem went away when we simply increased the CCA rating of the starting battery well above the recommended size. I don't recall what the manufacturer called for but we ended up with 1300CCA and never had another problem for ten seasons and over 2000 engine hours.

Bob daily- I looked up in parts diagram and did'nt see any glow plugs.
Northern Focus- It starts after three tries. It sounds like it is cranking O.K. I'll try the parallel and see what happens. I'm going for survey and sea trial on Monday. I'll post again.
Thanks all.

You stated that after starting and running it will start as normal, since the boat is a 2009 (17 years old) I would check the glow plugs, I’m not saying that’s the problem but it’s easy to check and eliminate as a source!

 

[Shellback]

I will definitely check it out. I didn't see them in a parts diagram on Boats.com. Do you know where I might get a part #.

 

[Shellback]

I meant Boats.net Cummins QSD 2.0 serial# - 88220584.

There's no glow plugs. 2700 hours of operation and owner maintenance. And a career as a machinery engineer. But I could have missed something that AI knows better.

Search the forum for Cummins starting problems. There's a whole history on this topic. May or may not have anything to do with that particular boat.

Thank you for verifying it
I will check forums.

I stand corrected!

Yeah no heating grid either. Let's ask it again and see what it says this time.

does the cmd 2.0 engine use glow plugs to start

No, the Cummins MerCruiser Diesel (CMD) QSD 2.0-liter engine does not use glow plugs to start.

Starting Mechanism

• • Direct Injection: The CMD 2.0L relies on high-pressure direct fuel injection and compression ignition rather than preheating the combustion chambers with glow plugs. [1, 2]
  • Service Design: Service documentation for the engine notes that the cylinder head has threaded screw plugs fitted into the ports where glow plugs would traditionally go on related non-QSD variants, which are only removed to relieve compression when manually turning the crankshaft.

You put ten years and 2000 hours on ONE battery? What brand please? Any special care or handling? Thanks.

This engine does not have pre-heat. It does need a strong start battery. I had the same issue until I put the better battery in. Advancing the throttle steadily while it is cranking almost always gets a cold start on the first try, even after not being started for a couple of weeks. (What you have confirmed is the ability of AI to find an answer any where it can, correct or not. Dan probably knows whatever you need to know about that engine.)
If you put a voltmeter on the start battery and read it while cranking that will tell the story about the battery size and condition. The voltage should not drop significantly while cranking if the battery is big enough. You might also check the prime by bleeding the secondary filter with the hand prime pump to be sure there is no air left in the filters. If the filters were just pre-filled and it was not pumped, there may still be air in one or both of the filters. Another basic item; are the battery connections clean and tight?

If you go to my first post you will see that I'm looking at this boat. I have'ntt bought it yet. tomorrow is the survey and sea trial. The boat was unused for a while when the broker started it up for me. This is when we found we had to give it three tries. The battery charger was plugged in and it seemed to turn over well. I know this doesnt mean a lot about the condition of the batteries. The service records I received look good but of course don't mention anything about the batteries. Thanks again guys you have given me a lot to go by.

Not what I meant. But re-reading I can see how it could look that way. We increased battery capacity to 1300CCA and never had another problem with starting. Batteries were replace every 3 years on general principles.
