I have a 1990 15 HP Johnson. My prop is pretty dinged up. I am looking to buy a new prop, but what is the right size and pitch. What is the difference in different pitches?
What size/type boat and material(Aluminum or glass)?? What is the size and pitch of the prop now? Figure each inch pitch you go down or up, will increase or decrease your RPM's by 200.. Might read this:<br /><br /> web page
