The 303 was the only Formula that the Hawks worked on. They tried it on several other models but they were slower and did not perform as expected. Everyone that drove the boat I sold twice, fell in love with it and it ,made finding the buyer that would pay the money the boat was worth much harder! Most were scared to own something that different. But try and get that boat from the present owner, Good Luck, and bring lots of money!

So true

How about a pair of BH drives on a 31 Sonic SS. There is one here in TX I am about to go look at.

I think Wellcraft used them on the 29 Scarab (some kind of special edition I think)for a couple of years and the worked pretty well, a friend of mine had one and I don't ever recall him having any issues.
