Gentlemen,

here it goes, i have a 28ft center console, 1991 yammi 250 salt. Boat is very heavy with very sharp entry points, its no speed demon by any means. I have been trying to tune for maximum perf/fuel consumption and have been left dumbfounded.

first setup is the original
ss factory yam prop 15x17

cruise @ 4200 25.5 26 knots wide open @ 5000 35.5 normal chop 37.5 on the glass

second setup solas 14.4x19

total crap ...... completely useless

third setup

turning point 15x15

cruise @ 4200 18 knots wot @ 5400 23.5 knots

fourth setup

solas 16x13 cruise @ 4200 22.5 knots wot @ 5100 26 knots


is there any more performance i can widdle out other than using a factory ss prop or just give up and live with it ?

thanks
