How do you pick Prop Pitch?

[adam24601]

Hi,<br /><br />I have a 22 foot Sunrunner with a 5.7litre V8 Mercruiser motor with Alpha one outdrive. I would like to order a new prop and use the current one as a spare. I do not know what is on there now as far as pitch. Is there a way to determine what pitch I need for that motor?<br /><br />Thanks,<br /><br />Adam

On iboats' dedicated prop site props.net we have quite a bit of info on helping you to determine the right prop for your boat. Click here to check out the info. It is still a part of iboats.

The only way to get the same diameter and pitch prop, is to get the dimensions or part number off of it.<br /><br />Before you spend your money, are you sure you have the correct prop on the boat now?<br /><br />You should be reaching 4400-4800 rpm at full throttle, if you have the right prop.<br /><br /> Click - Why rpm are important <br /><br /> Click - Prop Basics <br /><br /> Click - RPM Test <br /><br />If you click the links on the left of the pages, you will have mofe fun reading about props.<br /><br />Edit: See what happens when you open too many windows at once, someone else answers the post before you get to. Drats.<br /><br />.<br />.

Adam, Go to mercurymarine.com then to props. They have a very good guide for selecting a prop. Fill in all the fields you can and they will list at least 2 or 3 props for your application.

adam - Take your current prop to any prop shop & tell them the rpm at WOT. They can tell you what you have and recommend a new one to fit your needs.
