Hello again, After switching from force to Johnson I must be a little paranoid. I'm running a 17 foot Fabuglas open bow and the Johnson I put on had a 22 pitch stainless prop, I could only gain about 4800 rpm at wot with it, so I went down to a 19 pitch alum. prop and with little gas got 5200 rpm out of it, put 25 gallons of gas in today and 5000 rpm up river and the 5200 again going back down speed is between 45 and 50 not on GPS. I been in the prop section and walley seems to think there's a problem so I'm over hear now seeing what you all think. I mentioned to walley that when I put in, it vibrates a little in the no wake zone but holds a even 700 rpm. You click it one more time and start going it smooths right out. I hope I'm just being paranoid here, The motor does not miss a beat on the river and the boat probably weighs at least 3000 pounds maybe less with normal load and full gas. What do you all think??????????. Thanks in advance, Chris
