Going to the boat this weekend with my shiny new prop to try. What tools will I need to take off my ally prop off and put the SS one on. It may seem like a daft question but I haven't changed a prop before and the boat and manual are 110 miles away, thats a long way back for tools. The engine is an 18 month old 60hp Yamaha 4 stroke.
Ideally you need a prop wrench: http://www.steeldevelopments.com/erol.html and click on 'Accessories'. Alternatively a big spanner! You'll need to measure what size. You might also need a split pin, although you may be able to reuse the existing one. All the other parts (thrust washer, castellated nut, etc) should be reuseable. HTH
Socket or spanner.. Depends on the prop.. Removed mine recently to check the size, and used mole grips tied to my wrist.. That way I wasn't going to lose the nut as the rib was moored in the marina at the time..
