Cutting the Cowl
I wish you did not have to do it, but you have to so I need some advice. I need some ideas on how you mark the cowl so you know were to cut. A guy at my field told me how, but I just wanted to see all the different ways people did it.
Thanks for the help

RE: Cutting the Cowl
I use the method Ken described and it works extremely well. You want to make your holes slightly smaller than your outlines, then SLOWLY and CAREFULLY enlarge them until they fit the way you want. Plan on having the cowl on and off about 12 times before you get them right where you want.
I also suggest getting a couple of different grit TAPERED stones for your dremel and use the stones for the "fine tuning" of the holes. A big plus to the stones is that the finer grits will not chip the gel coat on fiberglass cowls. I normally use a dremel cutter for hogging the hole out to about 1/16" - 1/8" from drawn on opening. Then I switch over to the stones.
If the cowl is pre painted, consider putting masking tape over the areas you want to cut and draw your openings directly on the tape. Any residue left by the tape is easily removed with some alcohol.
