daves96xp 0 Report post Posted April 7, 2008 I traded out drives with a friend. I have a 99 220 explorer deck boat that has a 5.0 GL h.p. 220 engine. The outdrive was a 1.60. I now have a duoprop now with a 1.96. The props are F4's. I need some help with prop's?? I have no power out of the hole and the new out drive has gave me 10 mph more on the top in for a topend of 50 mph. Should I have them repitched or buy new one's. Please help.
