Hi Jim,

the tohatsu and yamaha 10 spline propellers are the same so it should go on no bother. If the mariner is a yamaha model it will have the same splines too.

Thanks,
Seumas

Hi rolfhat was the Ron hill chop on a standard tohatsu 30?
Do you know if they are the same hub length/spline as the 6e9 mariner/Yamaha 30? Jim
