Sullivan21 just done a 23 repower with a 250 merc 250 efi about that same year, I have a 225 like that and have the same prop as Don on the race boat and it dose around 47mph top with the 17p and needs a 19p or maybe 21p prop. Cruses well at 30ish around 3800 if I remember right. I love the 3.0 mercury's great motors
