    never heard anthing bad about them......I think Sonic just decided it was better to offer the 26 and the 31. not much of a step up from the 26 to the 28 so whats the point? Dano would be the guy to ask....
    If your boat has a sail do you ride a horse to the ramp?

    The only bad I hear is with twins it,s tight between the engines and that they are heavy, It just seems to be a few really good buys out there, and before I go chase one I want to make sure that it,s not some Ill Handleing tank, Do like the room it has

    Sonic 28SS


    I purchased a 2003 28SS Sonic that had 2 Mercruiser 396's (6.2L Engines with bravo 1 with 24 pitch bravo 1 props) in December 2007. I got the boat with 295 hours on it for $ 46,000 but did have to fix some owner neglect. Boat was in the saltwater for 6 months! Now in dry storage at marina. Had to replace cracked left engine gimball that was a pretty penny and upgraded the props to 26 pitch bravo 1's and had my service manager at the marina make the rotation go inward on both to get the max speed (63 mph at 4650 RPM's.

    The 28 SS comes in different engine configurations, depending on what original owner ordered at time of purchase. This particular owner wanted fuel efficiency, hence the 396's so their is a loss of top end speed.

    I do love the solidness of the boat and my boat handles real well in rough seas at a nice cruising speed of 30 mph in 3-5 ft chop and has plenty of speed for me at 63 mph in flat conditions.

    Depends what is important for you: Speed or comfort.

    I highly recommend the twin engine configuration.

    Let me know if you want me to e-mail you photos.

    If you do a 28 get one with twin small blocks, thats the way to go with them.

    Through a couple of transmissions in that 30' with a couple of big blocks and it's still a tight squeeze.

    with a single 502 worked with a 250 blower done by MRD. Boat moved and ran threw anything.
