Hi. I have searched all over the internet and . Can't find the right prop for my outboard. I can't even find the model number or serial number listed on any evinrude model guides. It is an evinrude 8hp Australian marine corporation. Model number AE8BACCS. As far as I can tell this number means it is an Australian evinrude 8hp rope start 1988 salt water. The serial number is A11600207. It is a prop with shear pin at the front and pin drive. All the props I've looked at on the site say pin drive but the picture shows it has a cog type drive? I would like to purchase the right prop if anyone can please tell me which is the exact one? Thanks.
