Here I am again with a newbie question, and I would like to mention all of you in our Spartan community that I sincerly appreciate all your advice,

I have heard a lot about opening up the intake port for where the water is picked up for the cooling lines, is there any video out there or does and donts for doing this, I was thinking a drill bit or a dremel tool and widening hole as wide and as far back as possible without going through to other side of rudder?
