Re: Performance: 23 with a 250
Zup, I have a new (to me) 78 with a 250 EFI on a bracket. Haven't really had time to wring it out yet due to the weather - being from VA too you know what I mean. It has the original stainless prop (let you know exactly what as soon as I can decipher it). So far, I've found about 30 knots easily at about 4400 rpm and 16-18 gph depending upon seas. Brent Pell, on this site, had some ideas about what kind of prop is should have. You may want to send him a note.
