    Mine with a 2 stroke normal load every day number is 84mph, light solo I see 90-92 depending on prop. It's been 94 when I had a p4. Mines for sale I just bought a sst try somthing new debating on trading for one of the new 300s

    They are the same hull and will be within 1-2 mph of each other.

    Very small changes to the hull but they share the same pad. From what has been guessed the speed difference is from having a bigger open area on the sst causing mroe wind drag at top speed.

    Is the console moved to the front more in the sst?

    I like my SST. Very well but still miss the performance of my old 20xd.
