1974 IMP Ford V8 188hp,Pre-Alpha out drive: I had the new lower shift cable perfectly adjusted when running on the muffs without the prop (easy, smooth shift, quiet with just a little chirp) Tonight, when I installed the stainless steel prop that came with the boat(for the first time) the shifting was a lot louder into forward, and would barely get/stay in reverse. Does the extra weight of the prop affect it that much? Would an aluminum prop be better for this drive? Or,is this not unusual and I should adjust it again with the load? Will it change again on the lake?<br /><br />Sorry for all the questions, I'm a little confused about this.
