To avoid personal injury:
· Do not bleed a hot engine as this
    could cause fuel to spill onto a hot
    exhaust manifold creating a danger
    of fire.
· Do not mix gasoline or alcohol
    with diesel fuel. This mixture can                                                            Diagram 1b

· Do not get diesel on the flexible
    mounts ­ they will deteriorate
    rapidly if soaked in diesel.
· All fuel must be removed from skin
    to prevent infection.

Beta diesels are very reliable if installed and serviced correctly, but problems can occur and the following list gives the
most common ones and their solution.


Possible Cause                               Solution

No fuel:                                     Turn fuel cock on and fill tank.

Air in fuel system:                          Vent air (see initial start-up)

Water in fuel:                               Change fuel filter and bleed system.

Blocked fuel pipe:                           Clean out and bleed system.

Emission durability.
2003/44/EC ANNEX 1, B3.

      The engine must be installed, maintained and operated within the parameters detailed in the
      Operator's Maintenance Manual. Maintenance must use approved materials, parts and
      consumables. Should the engine lie unused for a period in excess of 6 months it must be
      inhibited otherwise it will deteriorate with resulting decrease in performance. See also the
      Winterising and Laying Up procedures in the Operator's Maintenance Manual.

      The fuel settings of the diesel injection system must not be tampered with otherwise the
      guarantee will be invalid and the performance may fall outside prescribed limit. Such
      adjustment cannot be allowed under the terms of the emission certification.

      Performance of the engine depends upon the use of correct fuels, lubricants and inhibitors.
      These are fully detailed in the Operator's Maintenance Manual.

      Particular attention must be paid to the installation with respect to the exhaust system. The
      system must be designed so that water cannot back feed into the engine. The run must be
      such that the back pressure at the engine manifold does not exceed the level detailed in the
      Operator's Maintenance Manual. Wet, water injected, exhaust systems must be at least the
      bore mentioned in the Operator's Maintenance Manual and should the run be excessive this
      bore must be increased accordingly. Back pressure is measured at the outlet of the engine
      manifold before the water injection bend or dry bellows.

      Our experience over 14 years has shown that properly installed and maintained engines hold
      their performance without major mishap even when running hours exceed those mentioned in
      the Recreational Craft Directive. It is the owners / users responsibility to ensure that the engine
      continues to function properly and any malfunction must be immediately investigated. The
      Trouble Shooting section as detailed in the Operator's Maintenance Manual is particularly
      helpful in this respect. Engine performance, especially with respect to erratic running, exhaust
      condition, low power output and high oil consumption are indications of engine conditions
      that may result in emissions outside the prescribed limits and must therefore be investigated
      and rectified immediately.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
