To Hooter,bworner,Flyswatter and Bama96 thanks heaps for all your comments , i too have heard the yamie 150 punches above its weight at max rpm and with a full tank of gas, live wells full and 2 on board i can put up with waiting a few seconds to get her moving , if i can it to run 65 mph i will be very happy ( we run our boats in saltwater a lot and i think 65mph is on the cards) I currently have a yamaha four stroke that runs a max rpm most of the time……240 hours and i have only had to change oil and 2 impellers , it never lets me down even though i run it at full noise most of the time.Really good to hear an evinrude owner giving the yamaha the thumbs up too ! I am only a skinny bloke (so is my regular fishing buddy) so i think the 23″ prop should work well.Guys i really appreciate your comments , cheers
