Lower legs should be streamlined but yours looks the opposite and that appears to be where the water is shooting up from. Perhaps you could take a pic with the engine raised while out of the water so we can see lower leg.
Wow - thank you for all the responses so far. Much appreciated!
The boat isn't stored at home, but I took a couple of photos of the outboard when I got it which I have just put up at https://picasaweb.google.com/1043743...42706542699698
Not a stupid question at all as it does look a bit weird, but I am pretty sure that the lump of metal is supposed to be there. Will have a look in the instruction manual tomorrow to make sure I haven't made a real schoolboy error.
I would tend to agree that it looks as though it is too low, but the cavitation plate is pretty much skimming the surface of the water once on the plane (which I thought was about right) and it definitely goes a lot better with the motor sitting straight on the transom and it cavitates (I think? - you can feel the power slipping but the revs surge) a LOT more when I lifted the motor. Any higher and I think it will lose all power and barely move.
If I did lift it to stop the spray problem, are there propellors which would cope better with being at the surface of the water? There is plenty of water coming out of the cooling system, so I think it can handle being higher, but the lack of power and constant cavitation was frustrating.
There is also the slight problem of the clamps being off the top of the transom if it goes much higher. I want to bolt the motor on, but only once I am confident that the height is right. When I use the decking plank, I was really worried about the clamps popping off as they were very high.
Any other theories?
Thanks again to everyone - I am really grateful.
