Flex shaft to motor Coupler Question

I am setting up my 1/4 inch flex shaft to my motor coupler and just like to know how much of the flex shaft do i need to have inserted into the motor coupler. The coupler is a vice type that clamps down on the flex to hold it secure.

I try to fit my flex's so that it will end up with the desired clearance from prop dog to the stinger/strut and the other end of the cable inserted in the coupler until it's bottomed out against the motor shaft.

I second that Bill.

I notice that you are close to where I live.
We have a club at the Boondall Entertainment Center where we run every Saturday (today included) if you want to come along for a chat. Who knows, you might even join the club. Not only fast electric but Sail, Steam, Submarines, & Scale boats too.


All the best.

Thanks for the replys, I am at the stage of mounting the motor mounts to the hull so was curious as to how much flex to insert into the coupler. Just getting everything lined up and market out before epoxing it all down.
