Performance: 23 with a 250
 

Anyone have any real world numbers for cruise speed, top end, and type of prop. Thanks

Mike

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.

Running a 250hp with a S/S 17" Viper Prop without a bracket on my 23'. I have a T-Top, 135 gal fuel and 15 gal water and equipment:

According too GPS and system matched gauges,
CRUISE at 4200-4300 rpm = 29 mph to 30 mph
WOT at 5800 rpm trimed = 45 mph

Hope this helps [img]images/icons/cool.gif[/img]
