Re: Engine diagnosis Yanmar 7.5 hp...
the reason they say that is so your not running water through the engine for minutes at a time where its possible to get water in...
having said that max cranking times should never exceed 30 seconds...as it will damage the starter motor and overheat the wires on most any engine, especially diesels with their high comps to turn over
regarding the old fuel use a manual or electric pump and pump it out of he tank
rinse with fresh fuel a galon or so, pump out again...
dump a can of seafoam in tank then fill her up...this is good enough for most any tank that isnt completely trashed and old.
yes any crack anywhere in the fuel system is enough to hiccup a diesel, when there are more than one crack or a really bad fitting or loose banjo bolt etc the diesel will simply stall out and not start again.
sometimes you get lucky with a seal on the bottom of the racor fuel filter if you have one or something like that
but a new to you engine with unknown maintenance best just bite the bullet and get a good fuel filter(water separator if you have the change) new hoses and clamps, as well as new crush washers for all banjo fittings...
Islander 36 no longer for sale...its MINE!
