    You have to take the bolt out to install those. The wave eater ones have tabs that grab the bolt to keep it from backing out. The $99 kit comes with couplers and clips.

    Is there a problem with removing the bolt? Is it just 3 extra bolts that have to be removed or is there more to it?

    Not a problem removing the bolts just make sure to loctite them as they have been know to back out. Wave eater brand has tabs that grab the head to prevent this.

    Are those other pieces necessary? The 2 couplers with the wave eater clip brand? Again , Im not very familiar with what either of these pieces really do.

    The couplers are the pieces that connect one power valve shafts to the next. When I turned the wheel on mine by hand the #1 shaft moved about 1/4 of the way. The waveeater couplers have no slack on mine now. It makes sure you have no loss of performance due to power valves not opening all the way.

    As told to me by Lowell Horning, the slack that is found with the factory couplers also allows the valve to bounce around a little bit due to vibration. This causes the shaft to eventually break. Zero lash couplers eliminate this. There are a few positive zero lash coupler techniques. The wave eater coupler is one type but can still develop some slop over time but is much better than stock. The stock plastic pieces on the factory couplers can also still be used but should be secured positively with pinch ring (Oetiker) clamps. This maintains zero lash. On my boat I use RPM couplers that I modified...I don't think they're made anymore.
