Re: Yanmar Diesel Won't Stay Running

Coming across the Atlantic we had the same problem. I decided it was a problem with something blocking the tank. I took off the

Hose leading to the tank and put it into the bell of the ships horn. When I heard bubbling I stopped.

When I got to the USA, I drained the tank. Behind the fuel valve Amel mounted a screen. On Kimberlite you need a very thin wrench to remove the valve, it used to be called a tappet wrench.

My tank inspection ports were sealed with blue silicone.

Pieces of the blue silicone were blocking fuel flow,  I flushed the tank and ran it through a filter to get out the blue stuff. Permatex recommends Moto Seal for replacing the tank gaskets. It is used on motorcycle gear boxes and is meant to be easily disassembled to change the gears om Motos for different tracks.

 

This is very unique and if all else fails possibly this is the problem, however I think it is something much simpler.

The mechanic at the marina asked the same question about the auto-shutdown feature, so he's investigating that. I am about to pump some fuel from the bottom of the tank to check for water. I will also check for a vacuum on the fuel line, that's a good idea. 

 

Thanks!

My first thought is also fuel supply.  One time we started our engine with the fuel shut off valve closed...she ran perfect then just quit.  I can see the engine pulling a vacuum on the fuel line stalling ...then as the vacuum leaks off being able to restart.  

 

Now my second thought is based on you saying it was a new engine.   Does the engine have any automatic shutdown features like the genset?  Recall the genset has a host of conditions that will cause the machine to shutdown.  Just owndering if the new engine presumably with a computer is doing something on it's own.

Mark,

 

Unfortunately not. But I think I can put a hose in the bottom of the tank and pump some out to see. At least that is the current plan as well as ensuring the filter is clean.

 

Thanks,

Mark,

 

You have a fuel problem. Do you have a filtration system that allows you to check for water?

 

 

With best regards,

It's been several months since my wife and I left our boat up in the Chesapeake and upon arrival today to have it hauled for a long over due cleaning. The Yanmar diesel fired right up, but then after a couple of minutes dies. Wait a couple of minutes and it fires right up again, runs for a couple of minutes and shuts off. It runs smoothly and fires up instantly so it doesn't sound like she's starving for fuel or air. The engine only has 30 hours and has be very reliable.

 

Any ideas?

 

Thanks,
