Dave,The 175HPDI has surprised and impressed way beyond my expectations but the key to why this boat has performed better then my previous Sabre is what BassCat did to the hull. I know they would not share their design secrets but this hull is different. My previous Sabre was already impressive but the current Sabres Hull has evolved into something even better. It drives better and is faster from my experience after having both. I bet it gets better gas mileage too. Ill soon find out because Ill be adding HBs NMEA2000 bridge to display engine data like MPG.Now I cant wait to to get my boat back after the 10 hour break in service. Im having my Kenwood 700U iPod Juke box installed and will be rocking it hard on the water.I dont care what 175 motor you put on this boat you will do 70 plus easily once dialed in.
