Re: Help With rebuilt boat!

You need to look at the prop on your boat. It will be marked with a part number that will either cross reference to a pitch or include the pitch within the part number. Get the information and post it here and there are several people that will be able to assist you. Nobody can really offer up a pitch suggestion without knowing your current pitch. I will say that you have a rather large boat for the size engine so I'm sure you'll end up with a rather low pitch such as in the 13-15 inch range, but don't go out and buy a prop based on that.

I use to have a 27' Bayliner with the same outdrive & engine as you. I had a 16 x 16 and worked mint. The year before mine came with a 15.5 x 15.5. but they changed them to the 16x16.
