I changed out the old plastic Thru Hull's with some brass/stainless ones more boat "Bling" 
 
 
 
took a little work with the rotto file and a carbide burr bit it ate through the fiberglass wtih ease and left a nice smooth hole didn't chip the jellcoat at all
 
 
 
I got the pre bent hose at a ford dealership parts department the were off of a 1990 302 block had to change mine years ago and I rembered that hose was just what I needed for this job
 
 
 
now waiting for the bimni top to get here so I can get the side walls made up and get it in the water soon for the first voyage hopefully not the O'L "two hour tour"
