how much gap

[brian6989]

can someone tell me how much gap should be between white washer and the collet that holds the prop

[bbosncali]

About 1/8-1/4 between the stuffing tube and strut which is what I think your talking about

[brian6989]

ok thanks

[CHIEFY_44]

if u mean between the white washer and the drive dog its around 1mm

[bbosncali]

That's what proboat reccomends but its not enough for the flex shaft to flex. Should be the size of the flex shaft for space.

[brian6989]

yes the white washer and the drive dog 1mm and 1/8 is quite a difference is this something everyone runs different

hold the motor collet still with a wrench, turn the prop a little and you will see it compress, make sure your gap is enough to handle that compression. I'd go closer to an 8th inch.
