Brief Description: Throttle and Prop pitch firewall penetration insta
I had two steel eyeballs that needed to be installed. The firewall has 3 holes in it for the prop/mixture/throttle. I'm using EFII ignition, no mixture needed. I marked the hole. Drilled the 6 1/8inch holes around ther outside of the passthrough, then marked the inside. I used a large and small grinder to form the holes.
I also created a stiffener for the outboard ledge of the battery box lid.
