    Diesel additive

    So, because the boat in my details has petrol engines, I’m not allowed to own or care about other diesel engines ?

    Diesel additive

    OP isn’t a “member”, so someone posting a link to “member only” sections is probably less than helpful. All the advertising on my screen doesn’t pay csr enough? They need to gouge for access to the good sections?

    Vacuflush... Blocked or Pump Vacuum?

    The duckbills are one way valves, that are made of rubber and look a bit like duck bills.... they are what makes the system work - if your system builds and holds vacuum, they are most likely fine. Be very careful using plungers on vacuflush systems as the action of a plunger can invert a...

    Better replacement for this coolant into intake manifold line?

    To be honest, it looks just fine. Clean the threads with an old toothbrush, lube the threads and gently put it back together. They probably discontinued the part because they weren’t selling any.

    Film behind boat?

    Could be a failing fuel pump/injector causing gross over fueling. Could be a faulty seal on the trim system Could be a faulty seal on the outdrive. Could be a faulty oil cooler or power steering cooler. My money is on fuel pump.

    04 300DA aft accessory

    You need the owners manual for your boat - in there is a wiring diagram..... most likely the wire you need will be coming from the aft eim in the engine bay, it won’t be particularly long and most likely just buried in the loom. You’ll need to identify it by colour and wire number (from the...

In my 2006 300da, the vaccu-flush unit has 4 duckbills that are a larger size (possibly 2 inch?) on the vacuum generator, and 2 duckbills of a smaller size (possibly 1.5 inch) on the macerator/discharge pump. Somewhere on your unit should be...

    New batteries...old charger?

    Agm is a construction method. What sets voltage requirements is chemistry. (Not simply “lead acid”, but any other alloyed metals in the lead (antimony and calcium to name 2 common ones), any other additives in the electrolyte) Get the voltages wrong you ecectrolytically remove the water from...

    Coolmatic Freezer on 420da does not stay cold on 12v

    I have a portable fridge/freezer that used the bd50 compressor..... on mains power or on 24v, it’s an absolute champion and if you’re not careful it freezes the beer.... OTOH, on 12v it’s a tempremental little beyotch, takes ages to chill down, complains about voltage every time the compressor...

    Noflex Digestor for bilge cleaning?

    Ladies and gents, you are likely paying far too much for this stuff.... especially if you are paying 32 bucks for 16 oz... The active ingredient (80% by weight) is “disodium carbonate with hydrogen peroxide compound”..... there is another common chemical name for this - “sodium percarbonate”...
