TROUBLE SHOOTING
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 ENGINE DOES NOT START BUT STARTER MOTOR TURNS OVER OK
Possible Cause Solution
No fuel Turn fuel cock on and fill tank
Air in fuel system Vent air see initial in fuel Change fuel filter and bleed fuel pipe
Clean out and bleed system
Fuel filter clogged Change filter and bleed system
Fuel lift pump blocked Remove and injector Remove and clean
Fuel return not fed back to the tank Reroute fuel return pipe
Heater plugs not working Check wiring to the plugs and replace plugs if they are burnt out
Stop solenoid stuck in off position Check solenoid is free to return to run STARTER MOTOR WILL NOT TURN OR TURNS OVER VERY Cause
discharged Charge battery or replace Check alternator belt motor flooded with sea water Remove and
clean or disconnected or loose Check circuit for loose in cylinders Incorrect installation This is serious
check engine oil for signs of water
oil Ring your harness fuse blown Replace fuse located by starter motor or above flywheel housing and check for
wiring faults
FUSE
Note For convenience some engines are supplied with a spare
fuse and holder attached onto the main engine fuse holder
PROBLEM ERRATIC Cause Solution
Air in fuel supply Check supply system for leaks and fix
Fuel lift pump faulty fuel filter return not fed back to the fuel Reroute pipe or clean
tank or blocked pipe
Air filter blocked or blocked injector Service rpm in gear is too low this Increase engine tick over speed
must be 850 min
Faulty stop solenoid Disconnect wiring to solenoid If running improves check for a wiring fuel injection pump spring WHITE
OR BLUE EXHAUST GAS
Possible Cause oil level too high Reduce the injector Service ring and bore worn
giving a Get compression checked by your dealer or Kubota service agent He will
low compression advise action to be taken
Check that the breather pipe is clear Remove and clean out
and not BLACK EXHAUST GAS
Possible Cause air filter element Inspect and replace
Over pitched propeller engine will Check that the engine will reach full rpm in neutral if it does get the propeller
not reach its full rpm checked repitched if debris on hull Inspect and clean if LOW POWER Cause
is too big Change or gearbox reduction ratio relative Change
to propeller size
PROBLEM LOW POWER Cause fuel filter air filter Replace
Air in fuel system Check spring incorrectly mounted Dealer to lever control not operating Disconnect speed
control cable and move the lever by hand Adjust electrical load is too large on start Disconnect or reduce the HIGH OIL Cause
Solution
Oil leaks Check for rings worn Overhaul stem and guide worn Overhaul
rings gap facing the same Shift ring gap WATER IN LUBRICATING OIL Heat exchanger Cause Solution
Oil goes milky due to sea water Check installation has antisiphon valve been fitted Change engine oil and run
entering exhaust manifold and then engine for 10 minutes each time to eliminate any water Get fuel injection pump

RESPECT TO THE RECREATIONAL CRAFT DIRECTIVE 9425EC AND ANNEX 1 B3
The engine must be installed maintained and operated within the parameters detailed in the
Operators 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 Operators 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 Performance of the engine depends upon the use of correct fuels lubricants and
inhibitors
These are fully detailed in the Operators 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
Operators Maintenance Manual Wet water injected exhaust systems must be at least the
bore mentioned in the Operators 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 to ensure that the engine
continues to function properly and any malfunction must be immediately investigated The
Trouble Shooting section as detailed in the Operators 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 62

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 L-36.com 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.
