Was the 320 efi not even an option in 88'? Where do you think the 88' 272 sr-1 with 320 efi would end up on the spec sheet?

I got the sheet I was looking for from formula on friday via email, it was an option and they said they tested it and it did 65. with the 320 efi/bravos

Let us know how it goes, when do you plan on running it?

had it out this weekend, full tank<133 gals> 4 adults 60 degees. 67 on speedo and 62.8. gps, 4800 rpms could not trim out enough on stb drive, need to replace weak trim motor.

Awesome, sounds like it is running great. That much fuel with 4 people is a pretty good load. 1 person and half that fuel would probably get you 64-65. Although Formula said 60 with 270hp mags, 58 or so was more realistic with people I've talked to that had them.

well the boat performed very well ran cool oil pressure same exact on both motors, idles mint. hammer down goes on plan much faster than my 242 ss with a 4 blade. I will be replacing the stbd trim motor so I can trim it under full load. it sounds real scratchy....at 62.8 gps and all that weight and basically no stbd drive trim, I should see 65 gps anyway and over 70 on the stock speedo. I like that the stock speedo reads a little high.
