Best bang for your buck on your 3.0l is a stainless 5 blade prop. Wakes the boat right up
My dad has one of those on hi 18ft open bow with a little 4.3 v-6, and it has no problems towing my fat ass out of the water on one ski with a couple big guys in the boat. I believe its called a Mercruiser High-Five prop.
