Dan, you dont necessarily need the plugs to try out your new Fury prop. It may be fine as is. Plugs can be used to fine tune the initial on pad hole shot. Just ease into the throttle the first time and feel / listen for prop cavitation or blowout. Imagine this, your Fury has plugs in every hole, you nail the throttle, boat is laboring to get on the pad. To gain a better / faster hole shot, youll need to start removing plugs to create air bubbles so the prop can in turn spin more free / easier. You keep removing plugs until you are happy. Put plugs in for the reverse.You do not need the blowout ring on the Fury. Jack plate height needs to be from 3/8 to 5/8 above flush. Remember, no two rigs are alike. Glynn
