  1. I have no knowledge of the Kromhaut, was it a 2stroke & if it was did it have a total loss oiling system, the reason I bring this up is that the 'Seffle' I had in 'Lily' was total loss lube system, it had a tap on the crankcase + a pipe to a catch tank The engine was normally run with the tap open, if the tap was closed & oil was allowed to collect in the crankcase after an hour or so of running the amount of fumes etc in the engine 'ole' was increased by a large amount as the crankcase induction contained an amount of lube oil rather than being more or less oil free .If this motor was similar possibly the oil in the crankcase was at a high level Although I would not think it would amount to illness or death, unless as stated it ran full time on Petrol/ Paraffin

    The Kromhout I had was a total loss oil system (M1) The engine room always smelt of diesel/fumes. Going through a tunnel near Kings Norton ? it was particularly heavy on the lungs.

  2. Are you sure a hose would survive an exhaust fire?

     

    I remember being rather alarmed the first time it happened - the cast iron exhaust pipe glowed and the stainless steel chimney had turned rainbow coloured when the fire died down.

     

    Imagine a 4" diameter blow torch with a foot of flame shooting out the end and you get the picture.

    Yes I have heard of this happening. I`m not sure the rubber would survive and it could be a fire risk in the engine room. My expansion box had an inspection hatch in the bottom and I fitted a drain tap to get rid of the oily tar that built up. This wouldn't help with sooty solids though.

    Thanks, this seems a Good Idea.

     

    Replacing the metal tall pipe on Reg with a length of plastic dain pipe causes a norticeable reduction in noise, surprisingly. I think this is due to the slight 'give' in the nature of the material. A length of rubber will probably be even more effective. Where did you find rubber tube that big?!

     

    Another idea, as a couple of people have suggested to me that increasing the length of the exhaust tube is the answer, is to insert a couple of metres of stainless steel flexible flue liner in a coil into the exhaust outlet from the expansion box.

     

    I got the rubber from a place in Cradley Heath West Midlands but I will have to search for the name. It was something like suction hose used on pumps and resisted the heat well.

  4. Week beginning 24th May is national boat safety week for the Fire service.

    On the 25th I will be in the area of Gas Street Basin , Birmingham offering free safety advice for things like cooking and escape plans for boat owners, including fitting free smoke alarms.

    If anyone would like us to come to your boat or you are passing through the area and would like this free service please let me know.

     

    Regards , Kevin.

  5. I did a patch repair on the Kromhout eXhaust, Firefly was for sale at the time. She sold not long after and last I heard the engine was coming out

    It was Florence you did the repair on.The engine did come out shortly afrer.New owner.

  6. Well that's rather delicious isn't it?!

     

    Any idea what engine? WFB are being terribly coy about it. Posssibly the reason it is so cheap.

    Edit to add, on the WFB front page it says it's a Kromhaut! Time to start looking for cash down the back of the sofa... biggrin.png

     

    I've been on this boat, its fit out is basic but fantastic. Its a well engineered boat built by a knowledgeable owner. The engine is almost a sister to mine, brought into the UK by the same person.

  7. Its quite complicated but simple to rev it out of gear ,if that makes any sense !

    When in neutral you cannot rev the engine as a cam reduces the revs to tickover.You can set the lever half in gear and the gearbox "paddles" the shaft, this allows you to reach a point where the revs go from tickover to full within a couple of MM adjustment.

    Ive cleaned the injector, numerous times, refurbished the one way valves in the supply line and cleaned the pump.

    The only thing I havnt altered is the spring tension on the govenor.I think Ive nothing to loose so that is next.

  8. Right,

    I’m still having a few teething problems with the Kromhout. I’ve cleared the injector and I think that’s ok now. It starts easily and runs at tick over well. I can’t get it to rev up though.

    I think it may be the governor which is centrifugal and on the back of the flywheel. It moves a collar with a cam on, back and forward. When its static the collar moves to full cam by spring tension. Adjusting the throttle lever up and down raises and lowers the fuel pump so fully lowered the fuel pump hits the cam on lts longest stroke giving a big squirt of fuel.

    When its running the collar doesn’t seem to move far enough for the full cam to line up with the bottom of the fuel pump. I think it’s held back by a lack of spring tension to overcome centrifugal force.

    It has run in forward and the collar pushed (manually) to full cam and it easily turns the prop, so it’s not so overproped to stop it spinning up.

    So if I adjust the tension on the weights it should resist centrifugal force pushing it off cam?

    Any ideas.
