    Glad you've got the fan guard done.



    Next thing is to sort out the tip clearance of your blades. The gap between the end of the blade and duct is mahoosive. If you get the gap down to 5-10mm then it will be more efficient and quiter.



    Keep going friend and hope to get to Greece for a cruise sometime!

    I see rubber mounts at top of engine frame to duct...

    If you make tip clearence lower, I think is better to remove the mounts at the top... or else you will crack the impeller...

    The tip clearance is 7.5mm .This is the manufactures’ set ! The picture is from built period and the engine is not at the center (only 3 screws!!)

    All frames must have mounts ! I think is better to put mounts and in your hovercraft !

    mounts only work if what you are bolting them to is solid most GRP ducts flex so they are not realy working as well as they could
