"Can any one tell me please, how much end float I should have when I pull the prop back and forwards? Put my project Donzi in the water for the first time today and she seems to run well, but I did notice a slight vibration. Not sure if this is normal as I have only had out boards before.It is no where near as bad vibes as a two stroke so I may be being to finicky but there is a bit of end float ?? Thanks to all that have helped me on this site in the past. Your knowledge is priceless

Thanks Marada. Thats roughly wat I have.How much vibration is acceptable. I realise this is a difficult thing to define. As it was my first run I only went to about 2500RPM. Does the engine smooth out above this or will it get worse?

"Is it engine vibration or something in the drive? Which drive do you have?
What condition is your prop in? Bent / broken blades will cause quite a bit of vibration. Was the vibration at all engine speeds?
If the engine is running rough could be plugs, plug wires, points if you have them, carburetor etc."
