Hello, I finally got my Impulse 31. I have begun to modify it. I am adding the dual rudder kit. My question is I need to drill the hull in 2 locations since I will be adding a separate cooling line for my Seaking 180 esc. What should I use to drill the fiberglass for the tube entry in the rear of the boat and for the bulkhead fitting for the cooling system exit on the side? I have never drilled a fiberglass hull before and I don't want to crack the hull.
Thanks
Thanks
