well I found some info in the Sonic owners forum about the boat with blackhawk drives, looks like it was the only one built, might be one to stay away from!

I saw that boat on traderonline looks nice
but if those blackhawks arent mounted at the right
height it wont run very well, your should take it out
for a trial run to see how it handles.
I like the boat too, but if its rigged wrong skip it

Hey thanks for the tip there, that 95 sonic with the blackhawks is the one on traderonline, its also listed with bullock marine in seabrock tx. {about an hour drive for me} the price is right if the boat checks out. I just thought it was strange seeing those drives on that hull!:confused:
