Engine has to be removed.

Yeah that's what I thought, manual isn't to clear on that, thanks picklenjim.

I have 2 brand new mechanical shift conversions if anyone is interested, 2 brand new gimble rings that were mercurys last design with the u-bolt, big and small block drive plates, lower drive case and a box of pilot bushing that goes in the crank for the output shaft support of the merc trans, these are a must when using a merc trans. The bushing need to be turned down on a lathe for proper fitment. Also a couple of transmission that will need to be rebuilt before installation.

I need the pilot bushing for the crank shaft, are these still available?

I've got them in stock. P/N: 23-71647. Offshore Performance Specialties Don Carter 239-489-0884
