I see this is an old post but the 320 EFI brought back some old memories.

In late '86 I bought one of the last Formula 272 LS boats built at the Miami plant. I was doing some work at the local Formula Dealer up the road and made a connection at the plant. I "custom" ordered my boat with twin 320 EFI's on Alpha SS drives. It was the only one I ever saw...though there might have been a few before mine. I have to say the boat would scream!!! In those days if you had a boat that ran over 65 you were way ahead of the crowd and mine would run 74 speedo with 23" SS props at 5500 RPM with thru-prop exhaust!!
I used to troll for whores over at Shooters and Bootleggers on the ICW in 'Lauderdale and I got to tell you that 272 was a real babe magnet.
I wish I had an updated version of those engines for my 255 Liberator.
Damn ...the '80's were great in South Florida

1991 Checkmate Exciter GT 320EFI
I had sold a couple of Checkmates back in the day, that had these motors w/Alpha SS drives. They ran real well....however, even at the time(early '90's), they had a reputation for electrical gremlins in the computer, and oil consumption. I remember that they were an adaptation of the short-lived Crossfire injection that was used on some Vettes around the same time. I recall a particular 21 Checkmate that would run 70+mph w/the 320/Apha SS pkg. if you had the stones to hold on.

I purchased a 1991 Checkmate Exciter GT from Columbia MO. The boat was a closed bulk head with the 320EFi / Alpha SS package. I contacted Checkmate and Mercury and they noted this is a rare combination. The motor runs outstanding and it was sold to Kunkle's Marine in Ohio. This Exciter GT was a Persuader GT with a raised exhaust system due to a back pressure issue they had in early 1991. It runs very hard with the 320EFI motor and just had the Alpha SS rebuilt last year.
