On my recent trip to Kangaroo Island, I ran into a couple of friends who recently bought a delightful little 25 foot sailing boat. Not sure of the make, but very tidy and looks like it will be a joy to own.
It came fitted with a Bukh
10HP vertical shaft engine
with a sail drive, but I was surprised to see an outboard
on the back. It turns out they have been having some problems starting the diesel
. It has been to a couple of mechanics, and they get it going, but it stops not long afterwards. Of course they probably should be going back to the mechanics to ask for an explanation but they are not confident enough to do so, and it is made difficult because the mechanics are miles away on the mainland.
Now they are pretty much out of cash to spend on the engine
too. Their son has gone through all the motions, and I peered over his shoulder offering useless advice and I could see he has covered the basics.
Engine is cranking over pretty fast, (though compression
does not seem all that great, I am not sure what is normal for these engines.). Fuel
is getting to the injector body on the head
, cracking the line between the pump and the injector body produces pulses of fuel
as the engine turns over, not at great pressure but I assume this is ok because it is only fuel pump
pressure at that point, not injector pressure.
I could see no evidence of a glow plug
for the engine.
There is an electrical
device plugged in at the injector body that appears, from looking at online copies of the owners manual, to be a temperature sensor of some sort and therefore not essential to start the engine. I mention this because I checked to see if it was getting power and it was, but it was not passing any current
. I assume it is a switch that makes a circuit when it reaches a proscribed temperature.
Anyway, I know nothing about these engines so I thought I would ask for ideas here. I would particularly love to know if there are things that need to be done to start them, and also a description of the expected compression
would be interesting, I was just a little unsure that there was adequate compression.
Over to you for advice,
