I have a 150hp Yamaha v6 2stoke outboard. I'm looking at ordering a new prop for it but cant find any measurements on the prop itself, the only thing on there is 17M no diameter or pitch. My boat is a 7mtr Excalibur and with my current prop I'm getting 43kts with 220lt and two up. when fully loaded with 6pax I'm getting 40kts and 5500rpm. any recommendations on prop sizes? I'm finding it hard to get diameter/pitch sizes for "standard" props, thanks guys!
