    Props

    I have a 6.7 mtr aluminium boat (Barcrusher) fitted with a DF175APX. The motor came fitted with a 3X16X18.5R prop and I have a spare prop which is a 3X15X21R. Can someone explain what the effect of changing props would have on performance or fuel economy etc.and which would be best fitted to my boat which is only used for fishing off shore

    Suzuki motors/lower units/gear ratios prefer large diameter, large pitch propellers. You want to run upper rpms at top speed. Your boat decides what kind of propeller will lift best. You might try a Solas Scorpion with a hub kit to fit your motor. They are 15+ in diameter and offered in tall pitchs.
