Just got off the phone with my dealer about the prop issues i have been having with my 11' LSV. Talked with the service dept. and they are going to have a Acme 1433 AND a Acme 1161 for me to pick the one i want! So any one running a 1161?? I do mainly knee-boarding, wake boarding, surfing and an occasional slalom run. i am leaning towards the 1433. So how much speed am i going to lose top end and will the fuel burn be greater with the 1433?
