Actually, prop testing is alot of work. I tested 6 props, which meant running back and forth from the trunk of the car to the boat with a prop, taking one off and putting another one on. Then trying to analyse what is happening in terms of whether or not it is a good prop, take readings, and watching out for the water patrol. The best part of the day was the boat ride after the testing, with Gregg and Don around the lake.
