Re: need prop pitch formula

Howdy, <br /><br />The internet is a wonderful place!<br /><br />Here's what I found:<br /><br /> http://www.rbbi.com/folders/prop/propcalc.htm <br /><br /> http://www.csgnetwork.com/marinepropcalc.html <br /><br /> http://www.mercurymarine.com/chapter_4_-_propeller_technology <br /><br /> http://powerboat.about.com/od/propellers/ <br /><br /> http://powerboat.about.com/gi/dynam....michiganwheel.com/MIWheel/HowToTech/main.htm <br /><br /> http://www.castlemarine.co.uk/pitch...bb/ultimatebb.cgi?ubb=get_topic;f=24;t=015554 <br /><br /> http://www.bassresource.com/fishing/props.html <br /><br /> http://go-fast.com/Prop_Slip_Calculator.htm <br /><br />The next one is a file that you download, unzip and install. I don't know how good it works. (According to the readme.txt file, it's a Windows 3.1 file.....It probably won't work using the current version of the Windows virus.....I mean operating system!!)<br /><br /> http://www.kencook.net/props.zip <br /><br /><br />There's lots of info out there. I would estimate the best prop then I would try to find either someone that is willing to "loan" you a prop so you can try it or go to a dealer that sells props and after you determine the prop you want try to get them to let you use a "loaner" (if they have one) before you buy it. Also check EBAY for used props. There's a lot of new and used props there that are sometimes priced and close at much lower than new retail!

By the way, <br /><br />A lot of dealers have prop calculators too!<br /><br /><br />Cheers, <br /><br />Rick

There's usually several new and used Stainless Steel props on Ebay at any given time.<br /><br /><br />Sorry for the multiple posts.....I pressed " " instead of edit!<br /><br /><br />(I hate when I do that!)

Re: need prop pitch formula

thanks guys;what i was looking for was a formula that used a measured template of the angle of the prop blade face of an unknown pitch prop to determine the pitch. i found it nov 05 but it could have been a much earlyer post cause i was looking everywhere.wonse more, the member who posted (his pic was a very very short boat with a huge outboard motor)if that helps identity.thanks again for your replys--------------ed cooper.
