18 inch diameter by 20° pitch but if you look at the 98 through 2000 they change the pitch to 21 I have a 97 and I am changing my pitch to a 21 I feel it will give me a little better cruise speed and fuel economy please try and also post this in our Express cruiser/ amberjack thread

Re: 330 1997 express cruiser propping
Wow thats a lot of prop for that boat compared to my 1998 330 sundancer. Mine are 16 dia 15.5 pitch. I have high revving engines and need a lesser pitch than the original 16 pitch but 20 pitch?
What ratio is the transmission? Mine is 1.5:1
Safe to assume you guys have 1.75:1?
