I have a 2000 Ranger 518svx with a new 200SS and have had quite the time finding the right prop. Local dealer has propped and repropped with a 3 blade with a 19p down to a 16p. RPM's revving up to 6400 with top speed at 50mph. I just know that can't be right. The hole shot is awful and while I suspect the weight from the batteries, jackplate and power poles to be some of the challenge I would certainly think I would have a better hole shot and may top speed somewhere in mid 60's. Greatly appreciate any suggestions on what to go with.
