Mercury 40hp to 60hp conversion

[sebslegend]

i have a mercury 2018 40hp 4 stroke outboard and i want to know if i can convert it to 60hp and what parts i need

Why would you want to do that.? Sell the 40hp. And buy a 60hp. Besides nothing will fit properly and the gear ratio will be wrong. You'll blow the 60hp up. Not worth it.
