    Question Vent holes

    I am currently over propped for my rig; I own a 94 175ZX Skeeter with a 2005 175Optimax and running a 26 pitch Tempest; maxing out around 5400-5500 rpms; all four vent holes are plugged at the moment; turning the 26" makes it a real dog outta the hole; especially when fully loaded with 2 guys and live-wells full. Will pulling some of the plugs help getting outta the hole;and what can I expect on the top end with the change. I had a prop guy just tell me the new 4 blade trophys would be the best bet for my rig but most guys seem to run 24 Tempest's; any suggestions much welcomed.

    I'm in the same boat and have been told to pull plugs one at a time . You can play around with different sized opening plugs too dial it in. Does not affect top end.

    The vents only affect hole shot.

    24 Tempest with one large plug at 3.75 for starters. After getting a good baseline for your prop guy he can then tweak it to perfection. Far better to start low on pitch and cup and go up than going down
