I damaged my prop today, I have a spare from another boat that I used to own, but it's a three blade instead of the four blade that is on the boat now. My boat is a Centurion Carbon Pro with the 5.7 PCM engine. I have to find a prop puller before I can take the old one off, all I know is it's 13" diameter (measured), four blade, left rotating. The spare I have is an Acme 13" x 12, three blade, left turning. Any issues with swapping that out that anyone knows of? I'm guessing it would take a week or more to get the original fixed, so the swap would be temporary. Also, just ahead of the prop is what appears to be a 1" spacer that is broken, it goes about 2/3 of the way around the shaft, the other 1/3 is broken off. I have no idea if that happened today or if it was already like that, nor do I know what it is for and if it's critical. I'm trying to get back on the water without having to wait until next week when the marine shops are open. Any help is appreciated.
