Location: New Brighton, MN | I'm putting a new prop on an old boat. I've never changed propellers, but it looks pretty simple. It looks like there's a cotter pin holding it together. Is there much more to it? Do I simply pull the pin and remove the propeller, replace and put back pin? It can't be that easy.....! Please advise. |

| i usually put extra grease on the shaft that the prop fits over too. |

Location: New Brighton, MN | Yes. I'm switching from a 15 to a 17 pitch. Hopefully I can get a few more Mph's out of it. |

| Hi Willis
Going from a 15 pitch to a 17 pitch is going to drop the rpm's. Always increase pitch lower rpms.

| dont forget to take that spacer thing out of your prop that was on the boat. it's round, like a washer, but much thicker and it has groves on it to fit securely on the shaft. one you remove the old prop, it simply comes out the round middle section of the prop. it should just fall out if you turn it upside down or use your finger/screw drive to pop it out. you have to put that spacer thing back in your new prop before you install it, or it wont fit right, you'll have problems.
