I have a 2003 38 Open w/twin Cummin's 6CTA (450hp) diesel's. The original props are Federal 24x28 3 blade props w/#7 cup..... I also purchased, from Tiara, a spare pair that had the same spec's..That being Federal E/P 24x28 3 blade w/#7 cup .... I assume you have the same engines.... I cruise at 2100 RPM/23.5 knots..... Have had both sets on the boat over the past 10 years and performance has been the same.... Does this help??
