I fished this weekend with a friend who's got an 08 21 I-Class with a 250 HPDI. Compared to my boat, 05 zx225, it is sluggish getting out of the hole almost to were you wonder if its going to get on plane. He's not looking for speed so does anyone have a recommendation for a good 4 blade prop? His current prop is a T1 25 pitch.
