30 ss on Ebay

Andy congrats you beat me by 400$ stinks to be me. I talked to the guy who had it he said that he ran it with 21's and he thought that the 23's would be best. That is the guy you bought it from not the previous owner.

yeah it came down to the last minute I've been looking for a Sonic for almost a year and that was the best deal I've seen so far, now I just have to make the 15hr drive to get it this weekend

I used to have a 1988 Sonic 30ss with with 350's.
The motors were the 320efi's with alpha ss drives spinning 21 mirage props. The drives were non counter rotating and with the 3 blade props and the higher X dimension I had some trouble getting on plane. Engine and drive package for that year ran extremely well. If you have the same drives I would look into getting the counter rotating gear set for the starboard drive.
Enjoy your boat, I had fun with mine for 9 years.
