i have a 1995 lund tyee 1950 magnum GS with a 200hp evinrude vindicator with a 14 1/2x19 steel prop. with a full fuel tank (60 gallons) and complete fishing setup, W.O.T. rpm is 6500, i am in south dakota (if it makes any difference). i was told the target range is 5500-6000. there are not any loaner props available in my area that i have been able to find to try before forking the cash out to buy the "correct" prop. i am curious if a 14.2x21 wont get me low enough, or if a 14.2x23 will be too low? just looking for good input before i finally make my own bad decision.
