    Why no 3 bearing mod with riva-skat 3 blade 15/19

    Ive read through a couple threads about the 3 blade props and some have made a big deal about not running it without the 3 bearing mod, why is that considering Riva isn't offering it up front with their new setup, secondly I noticed a couple people who have had trouble with the triple bearing so why the big deal with it and is it necessary once you put on the 3 blade impeller

    I would advise adding the triple bearing pump,SS wear ring and the front motor mount to this package. Would be money well spent.

    I have installed quite a few of these Skat tripple bearing mod pumps and even run one myself. The quality is first rate and Glenn over at Skat is great to deal with.

    The original 3 blades had balancing issues. From what i understand this new Riva/Skat 3 blade is lighter and doesnt have the harmonics we saw with the old 3 blades.

    I recently serviced the skat modded pump, and everything looked good, I polished out the some minor scratches that surprisingly rust very easy...

    keep the pumps lubed (spray lube into the prop area) with bomb spray when the ski sits on the trailer!

    Jer: you know I`m running the 16\21 3 blader, I can`t say that I feel harmonics or vibrations, that weren`t there before with the stocker...PR...

    Is the 16\21 an old design?...

    Jerry what do you think my best option is with the b kit the already existing 15/20 or wait forever for the skat 15/19

    Run the 15/20 for now and then when the 3 blade 15/19 hits try that. Thats what im going to do.

    Thumbs up

    You boys with ss rings are limitting yourselves in my opinion,,,,,,,,but hey,,,I`m drinking now! My Berkley still has a ring in it. Everyone I know with a jet still runs one. Thats from 70`s technology. The pump is howveer very thick aluminum yet someone on www.hotboat.com just blew a hole through the pump! He`s running unlimited hydro against v-drives,,,,and kickin` asss I might say. Keep squirtin`.
