Marc,
I used the original screws and just lined them up. The screw really doesn't need to go that far into the sea swirl box as far as I could tell (unless there was something else inside for it to screw into, but I wasn't cracking it open to find out

) but it looked to me like it just screwed into the thin plastic encasing the motor. Anyway, the screws went in nice and tight. I only used 2 screws as the bend in the plexi didn't allow me to use the other two holes in the sea swirl box. The two screws were secure enough for me. Unless my regal tang gets up there and gives it the fin slapping of a lifetime I don't think its going anywhere
