I'm currently stationed in Africa and I just ordered a 175. I ordered it with the 50 yamaha and I am very excited about going home to SEE MY BOAT and my wife (JK). I had a questioned about getting it to 40mph. I didnt really have the money to buy a bigger motor but I was wondering if it was possible to get the boat running around 40 without losing my hole shot time and not putting added stress on the engine. This is my first boat and this site plus the article in Field and Stream really sold me.
