it all started after I had the engine service and shaft replacements to my water pumps
Prior to this work the last time I had been out on the boat I sailed from Chichester to lymington at 3600 rpm both engines went like a dream
Next time out port engine was only pulling at 3400 rpm
So call to dave crawford engineer yanmar main dealer he sarted saying there was a plastic bag around props or some thing tangled says this could have happened in the marina as last time we went out it was fine(chichester trip) so I looked underneath with underwater camera nothing there not a dickie bird tiny little bit of weed under boat.
next thing he tried was taking off the fuel filters and found a load of sludge in filter says theres bug in the tank filter was duly cleaned and bug cleaner put in tank still low revs
Next trick was to sea trial boat and clean all fuel lines out remove and blast out fuel pipes still low revs
next trick was to run boat from a 5litre jerry can to chack there was enough fuel getting through still low revs
He says the next step is to service all the injectors big cost no boat for 2 weeks
Engines are yanmar 250s on shafts
What does the panel think is this the next step ? /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif
