2010 Tracker 175 TXW with Mercury Optimax 90 currently running a QA2040X 3 blade 12 3/4" 21p prop. With 3 people all over 200 lbs, 1/2 tank of fuel and loaded with tackle trimmed out at max rpm I'm getting 40 mph. Holeshot is good but I want some more top speed what would be a good prop to get? I need to replace anyway because I hit something and tore a chunk out of it.
