Just a guess on the 140s, 280 horse power with two drives will be significantly slower than my single, but faster than a 25 Bertram with twin 130s( a much bigger, heavier boat). 18 knots most efficient cruise on the Bertram, 23-25 knots on my Seafari, guesstimate on the 140s in a Seafari 25: 23 knots medium load, 21 knots heavy, lots and lots of wonderful torque. Prop selection will be critical.
