Hi All,
Does anyone know what size the prop should be on the Cobra 750 fitted with a Bukh 10 engine ?. ie Diameter / Pitch & how many blades ( 2 or 3 ).
Cheers.

Thanks for the prop calculater could be helpfull. I would like to know what prop Cobra fitted to the boat as I feel the prop thats fitted to mine could be the wrong one.

Cheers.

Hi Bill,
I stumbled across this thread. I have a Cobra 750 with a 10hp engine similar to yours. She has a two-bladed prop, but I'm not sure of the dimensions. I have no complaints with her going ahead, (but the prop walk in reverse is a pain).
I need to beach her soon for a quick check-over underneath. If you are still seeking info then I would be happy to run a tape measure over Kabisa's current prop and let you have the dimensions.
Kind regards,
Paul.
