    Volvo Penta DSP Prop Change

    With a peace of wood I was able to snug inner nut more which corrected the problem. Thanks so much for the replies.

    Volvo Penta DSP Prop Change

    Have purchased F3 props as we boat at 6000+ foot elevation and the F5's that were on it struggled to get boat on plane. Was able to get F5's off without any issue. I got the F3 rear on and have it tight (says to torque to 45 ft lbs but don't have a way to really get that exact with current prop tool) but when I put on the front F3 prop it hits the rear prop before I can get bolt tight. That makes it so the props can't spin. I have verified the part numbers on the props are 180 degrees apart, the rear nut is tight and nothing works unless I have front nut loose. I will order new nuts but wanted to know if there was a trick or something I am missing to get rear prop back farther or if that is even my issue? Thanks so much.
