| Prop question... Dear all, We have just finished testing of our 32 feet mahogany boat. Lwl=7.7 m Bwl=2.5 m D=4.4 t Engines&propulsion: 2 x yanmar 6byz 260hp@4000 rpm bravo one diesel X. ratio 1.5 prop: mirage plus 14 3/4" X 21 " Top speed is 42 kn at 4080 rpm with three persons on board. I think props might have slightly higher pitch. So we can match 4000 rpm. What do you think about 4 or 5 blade props maybe? thanks  |
