riva pump wedge.
Does this stage 1 pump wedge really do anything. I know they say it allows the front of the to get up higher for more top speed but I can trim my front up so far that my top speed goes down.

Yes you can..You can over trim your ski....Youll have to go out on flat water by yourself with a GPS and watch your speed and RPMs as you trim..You will see you RPMs and speed start to drop once you pass the skis sweet spot..Then once you do find your sweet spot,note that..Most say to run your trim 2 clicks above nuetral but seeing you added a wedge you might have thrown that out..Did you add the VTS extention rod too??If so your adjustment will be close to the 2 clicks but youll still have to find your skis sweet spot.

So really the wedge doesn't add any top speed at all. It just changes the sweet spot. Is that correct?

VTS extension rod a must, should not even sell wedge without that in my opinion
You'll have to as Jammer 1 about 'sweet spots'

Another thing I will say is results will vary from ski to ski. Biggest factor is probably the pump shoe alignment as we saw with PBJ's ski and the pump extension.

it is my understanding that the wedge straightens the water comming out of the nozz.le ..making it more efficiant ..as well as lifting the front of the ski ..a ski without trim it helps more than a ski with
i second get a ride plate ...if you ride salt go with a heat exchanger...

A stock OEM VTS rod is non adjustable..When installing a pump wedge it is recommended to use the Riva VTS extenion rod:
The Riva VTS extention rod comes pre-set to the setting for the wedge BUT can be adjusted to fine tune your trim depending on the rider and his/her preferance..To adjust the Riva extention rod all you do is loosen up the jam nut and spin the hyme joint in/out to adjust to your likeing..Then once you reach your desired likeing just tighten the jam nut...
