    this is on a T-X so I would not go smaller than a 83 and would also try a 84 if you have one it will lose the great hole shot with a smaller ring

    also if you bought the Rive nozzle be prepaired to drill and tap the nozzle to fit the T-X 300 bucks and you have to drill and tap it ot make it work

    riva nozzle

    so your saying i half to drill the nozzle to start with to get this nozzle even on the boat. i dont have a 84mm ring yet but i could get one it seems like they sell plenty of diff sizes. they say to shoot for 8000rpms when the rev limter is 8200. know with set up right know i have it seems faster then stock an revs are any where from 8080-8160 with the great hole shot

    yep if you got it in the last year Riva stopped making the one just for the RXT`s you will also have to remove the OPAS if you have not already because the nozzle does not have the hole for the fitting that operates the OPAS
