Outside of that your are using a hammer and block of wood which it a fast way to bend one of your blades out of pitch if you miss the wood. Most of all the autoparts stores around me will rent or loan gear pullers. Start with the autoparts and if you can not find anything head to the Marine Repair but like anything if a boat it will be more expensive there.

Either way it will take some whacking. Take a couple whacks and then tighten the trust bolt. Repeat till it pops off. Edited by Jeff on 10/05/07 - 12:04 PM 1993 23' Walkaround Whaler Drive

If you can take your time you can try PB Blaster and a puller over a period of days or at least a week (or more). Tilt the motor up. spray the PB blaster around the shaft and the prop. Tap the shaft with a mallet (tapping helps the liquid penetrate). then try the puller. If it doesn't come out. Spray then tap. Let it sit then try the next day. Repeat every day until it finally comes out.
