    21SST Speed Numbers

    Hey Bullet gents,
    What are some realistic top speed numbers with a 21SST w/ Mercury 250R 4S and 250 PXS 4S loaded to tournament fish?
    Thanks,
    Bigtione

    I'm running mid 80s with a 300 xs loaded to fish. I know it is not exactly what you ask for but just for info.

    In the right hands it would be a high 80's low 90's rig loaded to fish.

    Realistic (fishing) numbers imo: 250r mid 80s, Pro xs low 80s. I have no info on the pro xs other that the internet opinion that its not as strong as the r motor. My 21ss with 250 Opti fished at 81-82 with a gen 1 TM and 2 power poles. Again, that is fishing, loaded.
