Can I replace the prop hub on my 1984 mercury 90hp inline 6 outboard myself? Are any special tools needed? Will I be able to get the hub out myself or will I need a press? I have a prop with a spun hub. I found the kits online that just come with the rubber hub and the kits that come with the nut, lock washer, etc. Do I just need just the hub or do I need the whole kit?
