Bondo (or anyone else im my situation),<br /><br />My shift prop is great when it works perfectly, but lately I have been fighting with it quite a bit. <br />As I mentioned in my earlier threads, I have to basically cavitate the boat in order to up-shift (due to lack of adequate power/weight ratio), but it rarely goes all the way back down to the lower pitch when stopping. Also, most recently I have been noticing a heavy vibration from inconsistent shifting between the blades! I put my aluminum prop on to verify, and it is definately the prop.<br /><br />What CAMS are you using on your shift-prop with your 4.3? I am currently running the ZZ CAMS (mildest ones) with the weakest springs (suggested by L&S) since the boat is 2400# dry, and the 4.3 is 175 HP. <br /><br />Maybe the steeper CAMS or springs would provide more positive results?? I think once I upgrade the engine to Vortec 4-bbl, I'll be able to use other CAM/Spring combinations...<br /><br />Thanks!
