Mike, just curious - did you know those figures off the top of your head?

You're talking to a guy who can't even get the gd prop off! Having had a new shaft installed this summer, I figured it would be a simple thing. But I tried this weekend, and tried again, and tried some more... I removed the nuts on the shaft, then tried hitting it with a rubber mallet, rotating, whacking it, rotating, whacking it.. I tired putting a block of wood against the prop by the shaft and whacking that, ad nauseam. I ended by spraying the thing down with WD40. I hope that's not bad.

Got any tricks? A quick web search tells me I could use a "prop puller", whatever that is.

I'm trying to remove it so I can take it a boatyard and have it looked at.
