I've got a couple things for free and a couple things for cheap! (Feel free to reply with your own stuff to swap/sell.)
Cable, Whale tail & Mich Wheel prop are free. I'd like $25 for the Gil 'Six Gun' composite prop. I believe it fits a Mercury OB, and is a 17p.
Mich. Wheel came off of Goldie, and is rough...and is a 'get ya home' spare. I used it the first year I had the CVZ up and running, and seemed fine.
I have a 19p Gil Six Gun that I keep as a spare for my boat. Great hole shot, not so great top end. Best part is its compact storage, and individually replaceable blades.
