Aluminum might be a good idea. Galvanized pipe will build up scale and mineral deposits that could really screw up the engine.
Jegs has 1/2 inch aluminum for $25 for 25 feet.

Taylorman Where did you get the motor plate?

I had them customize it to my dimensions and put 3/8 NPT holes for the water inlets. I then cut it to fit my boat and cut around the fuel pump.

I build aircraft part-time, and we use stainless hard lines for everything from hydraulics to fuel systems, brake lines and more. Alot of the tubing and tools like cutters and flaring tools can be purchased here: http://www.aircraftspruce.com/

Taylorman,
Are you getting sufficient water flow through the -8, 0.035 wall tubing?

Kmenard, you'd probably get more response if we knew where you are located. If you happen to be in SoCal, McFadden-Dale, Corona carries ss tubing. It's reasonable as I did my entire Daytona in 1/2, 3/8. I'm thinking of doing my airlines in the garage with the same 1/2 ss. Bonaco's in Upland also carries tubing but they are more expensive. If you're in Edmonton, Alberta you'd have to ask Tom,Kim, or an Eskomo.
