Glencove Marine (Lake of Ozarks) has a 1995 303 with 502EFI's and blackhawk drives. Was this original equipt.? If so, how did they perform? Seems like an odd combo?

Never saw Blackhawks on a Formula before. I would have one concern - I don't think parts are available for them anymore. Might want get the hull I.D. number and give Formula TAG a call ... they can tell you if it went out of the factory with Blackhawks or not. 260-724-1412

weren't they more popular with small blocks?

Only one was built as I recall. It idled at about 10mph. My Formula rep,Jon Earl, sold it at the Miami show but had to deliver it down the Intercoastal. He kept getting pulled over in the no wake zones cause he was going so fast. He finally convinced the cops he was idling(he was) and they cleared him the rest of the way. It was a pretty cool boat,I thought it had been converted to Bravos,guess I was wrong. There are parts out there,just have to look hard. The Donzi owners website is a good source.
