i am replacing my impellor on
i am replacing my impellor on a johnson 1980 70hp 3 cylinder and have a question!
the new impellor has come with 2 wedge shaped keys to fit it with!
My original has a single slot that a half moon shaped key fits into to hold it in place.
do i need to put the orginal key in aswell as the wedge shaped bits? if i only put the half moon key it takes the slack up and holds in position however i am unsure as to weather it will stand up to the forces of the motor turning it! if i turn the shaft in a counter clockwise direction i can feel that the shaft moves free of its holding position.
any help will be greatly appreciated
