Engine faults are in most cases caused by improper operation or
insufficient In case of a fault always check first that the operation and main
tenance instructions have been followed
In the following tables information is given about the possible
causes of faults and suggested remedies Please note that these
tables can never be complete
If you are unable to identify the cause of the fault or to rectify it
yourself then contact the nearest service Warning
Before starting make sure that nobody is in the immediate vincin

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
