Installed my Merc Hi-5 19 pitch prop about a month ago, and WOW. Its like having a brand new boat. I have a 2007 Maxum 1800 SR3, and with this prop it is an unbelievable difference. Planes in seconds, tons of torque, Can ride at a much slower speed so the wake is much nicer. Cut a mph or 2 off the top speed, but I never haul ass anyway. With my sacs...I wouldn't change a thing.
Anyone else tried this?
