Switch off the Engine
Very often, we couldn't switch off our Volvo TMD22 with the key. The change of the solenoid brought help for a couple of days. A definitive resolution of the problem was in fact very easy: There is a gum on the solenoid which expands when the fuel gets hot. This is especially the case, when the engine runs a lot in idle mode (for ex. approaching a marina and manoeuvring the boat in a berth). The expanded gum doesn't fit any more into the fuel pipe and can't stop the flow. The conclusion for us was to take out the solenoid, carefully sand the gum a little bit to reduce its diameter. Since we've done this, no problems at all. Black exhaust-smoke on the side of the hull To get rid of almost all black material on our hull, we've installed an Algae-x (http://algae-x.net/), a fuel conditioner, in our system. Since 500 generator and engine hours we haven't change any diesel fuel filters – because there are still clean and proper (even the Racor pre-filter) – and we had no reason to clean the hull on the exhaust side of the boat :-)). There are other advantages, for example no need for cleaning the tank any more, etc. This great unit is a real pleasure … Hanspeter & Nathalie Wehrli SM #158 on the way to Ecuador
